SIMOREG DC Master 6RA70 Series – SIEMENS 6RA70 Conrol Module

SIEMENS 6RA70

SIMOREG 6RA70 converters are fully digital, compact units for connection to a three-phase AC supply. They in turn supply the armature and field of variable-speed DC drives. The range of rated DC currents extends from 15 A to 3000 A, but can be expanded by connecting SIMOREG converters in parallel.

Converters for single-quadrant or four quadrant operation are available to suit individual applications. As the converters feature an integrated parameterization panel, they are autonomous and do not require any additional parameterization equipment. All open-loop and closed-loop control tasks as well as monitoring and auxiliary functions are performed by a microprocessor system. Setpoints and actual values can be applied in either analog or digital form.

SIMOREG 6RA70 converters are characterized by their compact, space-saving design. An electronics box containing the closed-loop control board is mounted in the converter door. This box also has space to hold additional boards for process-related expansion functions and serial interfaces. This design makes them especially easy to service since individual components are easily accessible.

External signals (binary inputs/output), analog inputs/outputs, pulse encoders, etc.) are connected by way of plug-in terminals. The converter software is stored in a flash EPROM. Software upgrades can easily be loaded via the serial interface of the basic unit.

SIMOREG DC-MASTER Control Module Description (6RA70)

Applications

The main application of the SIMOREG DC-MASTER Control Module (SIMOREG CM) is conversion and modernization of DC drives in existing installations. In DC technology, many installations exist that are older than 5 – 10 years and still use analog technology.

When these installations are converted or upgraded, the motor, mechanical and power sections are left in the installation and the trigger and control section replaced by a SIMOREG DC-MASTER Control Module. The result is a modern DC drive at an extremely low price, with the full functional scope of the tried and tested fully digital devices of the SIMOREG DC-MASTER 6RA70 range.

The configuration of the existing components is adapted by simple parameterization. The SIMOREG DC-MASTER Control Module contains a power section for the field supply with a rated current of up to 40A.

Design

The SIMOREG DC-MASTER Control Module is characterized by its compact, space-saving construction. Their compact design makes them particularly easy to service and maintain since individual components are readily accessible. The electronics box contains the basic electronic circuitry as well as any supplementary boards.

In order to make optimum use of the mounting possibilities of the installation, the SIMOREG DCMASTER Control Module can be divided along its depth. In addition, the PCBs for the firing pulse generation and distribution and for safety monitoring and voltage acquisition have been designed in such a way that they can be divided and either partially or completely mounted outside the converter directly on the power section and connected with the basic unit via cable.

All SIMOREG DC-MASTER Control Modules are equipped with a PMU simple operator panel mounted in the converter door. The panel consists of a five-digit, seven-segment display, three LEDs as status indicators and three parameterization keys. The PMU also features connector X300 with a USS interface in accordance with the RS232 or RS485 standard.

The panel provides all the facilities for making adjustments or settings and displaying measured values required to start up the converter.

The OP1S optional converter operator panel can be mounted either in the converter door or externally, e.g. in the cubicle door. For this purpose, it can be connected up by means of a 5 m long cable. Cables of up to 200 m in length can be used if a separate 5 V supply is available.

The OP1S is connected to the SIMOREG CM via connector X300.

The OP1S can be installed as an economic alternative to control cubicle measuring instruments which display physical measured quantities.

The OP1S features an LCD with 4 x 16 characters for displaying parameter names in plaintext. German, English, French, Spanish and Italian can be selected as the display languages.

The OP1S can store parameter sets for easy downloading to other devices.

The converter can also be parameterized on a standard PC with appropriate software connected to the serial interface on the basic unit. This PC interface is used during start-up, for maintenance during shutdown and for diagnosis in operation. Furthermore, converter software upgrades can be loaded via this interface for storage in a Flash memory.
The field is supplied by a B2HZ single-phase single pair controllable two-pulse bridge connection.
The power section for the field is constructed using isolated thyristor modules, the heat sink is therefore electrically isolated.

Mode of operation

All open-loop and closed-loop drive control and communication functions are performed by two powerful microprocessors. Drive control functions are implemented in the software as program modules which can be “wired up” by parameters.

Technical data

SIMOREG DC MASTER 6RA70 converter

The SIMOREG is a line-commutated converter which requires the line voltage to commutate the current, it is not possible to maintain the current flow on failure of the line voltage (e.g. on a short interruption).

If regenerative feedback is used with four-quadrant devices, failure of the supply voltage orSIEMENS 6RA70 a line undervoltage can cause a fuse to trip (commutation failure). This is a physical effect of the converter circuit that cannot be prevented by closed-loop control. Single-phase alternating current is fed to the field circuit and three-phase current to the armature circuit. It is not possible to operate the power section from a DC system.

The SIMOREG 6RA70 can briefly be overloaded 1.8 fold if the device had previously been operated with a base-load current which is lower than the device rated current. If the device has been operated at rated current over a longer time it cannot be operated at overload. To avoid this, the thermal condition of the thyristors is calculated in the device to ensure the protection of the power semiconductors. Once the thermal limits are reached at overload, the current is automatically reduced to the rated current of the device or the device is switched off with an error message. The overload is configured using Catalog DA21 or the instruction manual.

The 6RA70 SIMOREG DC MASTER products will be totally discontinued effective October 1, 2020. From this time onwards, the product will no longer be produced, but spare parts will be available through October, 2022 (contingent upon component availability).

As an alternative, 6RA80 SINAMICS DC MASTER devices are available as compatible and innovative replacement products.

Mode of operation Optimization run

6RA70 converters are supplied with parameters set to the factory settings. Automatic optimization runs can be selected by means of special key numbers to support setting of the controllers.

The following controller functions can be set in an automatic optimization run:

  • Current controller optimization run for setting current controllers and feedforward controls (armature and field circuit).
  • Speed controller optimization run for setting characteristic data for the speed controller.
  • Automatic recording of friction and moment of inertia compensation for feedforward control of speed controller.
  • Automatic recording of the field characteristic for an e.m.f.-dependent closed-loop field-weakening control and automatic optimization of the e.m.f. controller in field-weakening operation.

Furthermore, all parameters set automatically during optimization runs can be altered afterwards on the operator panel.

Monitoring and diagnosis Display of operational data

The operating status of the converter is displayed via parameter r000. Approximately 50 parameters are provided for displaying measured values. An additional 300 signals from the closed-loop control can be selected in the software (connectors) for output on the display unit. Examples of displayable measured values: Setpoints, actual values, status of binary inputs/outputs, line voltage, line frequency, firing angle, inputs/outputs of analog terminals, input/output of controllers, display of limitations.

Trace function

The trace function can be selected to store up to 8 measured quantities with 128 measuring points each. A measured quantity or the activation of a fault message can be parameterized as a trigger condition. It is possible to record the pre-event and post-event history by programming a trigger delay.

The sampling time for the measured value memory can be parameterized to between 3 and 300 ms.

Measured values can be output via the operator panels or serial interfaces.

Fault messages

A number is allocated to each fault message. The time at which the event occurred is also stored with the fault message. This allows the cause of the fault to be pinpointed promptly. The most recent eight fault messages are stored with fault number, fault value and hours count for diagnostic purposes.

When a fault occurs

  • The binary output function “Fault” is set to LOW (selectable function),
  • The drive is switched off (controller disable and current I = 0, pulse disable, relay “Line contactor CLOSED” drops out) and
  • An “F” with a fault number appears on the display, the “Fault” LED lights up.
  • Fault messages can be acknowledged on the operator panel, via a binary assignable-function terminal or a serial interface. When a fault has been acknowledged, the system switches to the “Starting lockout” status. “Starting lockout” is cancelled by OFF (L signal at terminal 37).

Automatic restart: The system can be restarted automatically within a parameterizable time period of 0 to 2s. If this time is set to zero, a fault message is activated immediately (on power failure) without a restart. Automatic restart can be parameterized in connection with the following fault messages: Phase failure (field or armature), undervoltage, overvoltage, failure of electronics power supply, undervoltage on parallel SIMOREG unit.

  • Fault/error messages are divided into the following categories:
  • Line fault: Phase failure, fault in field circuit, undervoltage, overvoltage, line frequency
  • < 45 or > 65 Hz
  • Interface fault: Basic unit interfaces to supplementary boards are malfunctioning
  • Drive fault: Monitor for speed controller, current controller, e.m.f. controller, field current controller has responded, drive blocked, no armature current
  • Electronic motor overload protection (I2t monitor for motor) has responded)
  • Tacho-generator monitor and overspeed signal
  • Start-up error
  • Fault on electronics board
  • Fault message from thyristor check: This fault message will only occur if the thyristor check is activated via the appropriate parameter. The check function ascertains whether the thyristors are capable of blocking and firing
  • Fault messages from motor sensors (with terminal expansion option): Monitoring of brush length, bearing condition, air flow, motor temperature has responded
  • External faults via binary assignable-function terminals.

Fault messages can be deactivated individually. The default setting for some fault messages is “deactivated” so they need to be activated in the appropriate parameter.

Alarms

Special states that do not lead to drive shutdown are indicated by alarms. Alarms do not need to be acknowledged, but are automatically reset when the cause of the problem has been eliminated.

When one or several alarms occur

  • The binary output function “Alarm” is set to LOW (selectable function) and
  • The alarm is indicated by a flashing “Fault” LED.
  • Alarms are divided into the following categories:
  • Motor overtemperature: The
  • calculated I2t value of the
  • motor has reached 100 %
  • Alarms from motor sensors (with terminal expansion option only): Monitoring of bearing condition, motor fan, motor temperature has responded
  • Drive alarms: Drive blocked, no armature current
  • External alarms via binary assignable-function terminals
  • Alarms from supplementary boards.
Safety shutdown (E-STOP)

The task of the E-STOP function is to open the relay contacts (terminals 109/110) for energizing the main contactor within about 15 ms, independently of semiconductor components and the functional status of the microprocessor board (basic electronics). If the basic electronics are operating correctly, the closed-loop control outputs an I = 0 command to de-energize the main contactor. When an E-STOP command is given, the drive coasts to a standstill.

The E-STOP function can be triggered by one of the following methods:

  • Switch operation: E-STOP is activated when the switch between terminals 105 and 106 opens.
  • Pushbutton operation: Opening an NC contact between terminals 106 and 107 triggers the E-STOP function and stores the shutdown operation. Closing an NO contact between terminals 106 and 108 resets the function.

When the E-STOP function is reset, the drive switches to the “Starting lockout” state. This status needs to be acknowledged through activation of the “Shutdown” function, e.g. by opening terminal 37.

Note: The E-STOP function is not an

EMERGENCY STOP function according to

EN 60204-1.
