The dc drive system is a simple and excellent transmission scheme – so we have a reason to innovate for it. This innovative basic reason is that in the comfort and reliability of operation, in the aspect of economy and job characteristics, in terms of efficiency and starting, dc drive system in its proper application, has the advantages of it. SIMOREG ® DC – MASTER will provide the best features and intelligent – with novel properties, give new vitality to DC transmission system.
Adapted to the various application system using SIMOREG DC – MASTER, its application without limitation, its function, wide output power and voltage range, and the operation control of the general principles for the wide application in the field of industrial provides the best solution. Whether the simoregdc-master is supplied to a dc motor or a special occasion, it can always provide optimal performance and high intelligence.
The motor, the drive system’s motor organs, the SIMOREG dc-master and our motor make up the ideal combination of the transmission system. The compact Siemens dc motor is used worldwide due to its reasonable price driving technology and maximum utilization. The transmission system is rugged, durable and has a wide range of power, from 0.7kW~ 1550kW. Since the cold or strong
Forced air cooling, with or without fan, protection grade IP23, IP54 or IP55: due to modular design, can achieve the above arbitrary combination. What’s more, our dc motor can be integrated into the automation environment through the motor interface. – continuous monitoring, accurate diagnosis, effective maintenance and service.
The SIMOREG dc-master product family provides the best products for high – level driving applications and standard solutions. The product has extremely fast control characteristics: its current and torque rise time is less than 10ms. The output power ranges from 6kW to 1900kW for single-quadrant or four-quadrant transmission for armature and magnetic field.
SIEMENS SIMOREG 6RA70 GENERAL INFORMATION
Series 6RA70 SIMOREG DC MASTER converters are characterized by their 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 option boards.
All SIMOREG DC MASTER units are equipped with a PMU simple operator panel mounted in the converter door. The panel consists of a five-digit, seven-segment display, three LED’s as status indicators and three parameterization keys. The PMU also features connector X300 with an 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 OP1 S optional converter operator panel can be mounted directly in the converter door or externally, e.g., in the cubicle door. When mounted remotely, the OP1 S can be connected to the converter with cables up to 5 meters (15 feet) length. Cable up to 200 meter (600 feet) in length can be used if a separate 5 VDC power supply is available. The OP1 S connects to the SIMOREG through connector X300 using the RS485 interface. The OP1 S can be installed as an economic alternative to conventional door mounted metering devices (Le., voltmeters, ammeters, and speed indicator).
The OP1 S features a liquid crystal display with 4 x 16 characters for displaying parameter names in plain text. English, German, French, Spanish and Italian can be selected as the display languages. In addition the OP1 S can store parameter sets for easy downloading to other drives.
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 through this interface for storage in flash memory.
On single-quadrant converters, a fully controlled three-phase bridge supplies the armature. On four-quadrant converters, two fully controlled three-phase bridges are connected in an inverse-parallel connection to allow both positive and negative armature current. For the field converter, a single-phase, half-controlled 2-pulse bridge supplies the motor shunt field.
The armature and field converters can operate with AC line frequencies from 45 to 65 Hz. If required for a specific application, the frequency of the armature and field AC supplies can be different. The armature converter 3 phase AC supply is phase insensitive however on base drives rated 1180 and 1660 amperes, the 3 phase cooling fan must be connected to get the proper direction of rotation. The power section cooling system is monitored by means of temperature sensors.
The power section for the armature and field converters is constructed of isolated thyristor modules for converters rated from 15A to 850A at 460V AG-line voltage. The heat sink in this case is electrically isolated and at ground potential. On converters rated 1180 and 1660 amperes at 460 VAC, the power section for the armature circuit is constructed using disk thyristors and the heat sinks are at line voltage potential. The housing and terminal covers on power connections provide protection against accidental contact for operators working in the vicinity. All connecting terminals are accessible from the front.
All open 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 that can be “wired up” and changed by parameters.
