SIEMENS MICROMASTER ,MICROMASTER 420/430/440 series

MICROMASTER 420/430/440

The MICROMASTER 420s are a range of frequency inverters for controlling the speed of
three phase AC motors. The various models available range from the 120 W single phase
input to the 11 kW three phase input.

The inverters are microprocessor-controlled and use state-of-the-art Insulated Gate
BipoIar Transistor (IGBT) technology. This makes them reliable and versatile. A special
pulse-width modulation method with selectable Pulse frequency permits quiet motor
operation. Comprehensive protective functions provide excellent inverter and motor
protection.

The MICROMASTER 420 with its default factory settings, is ideal for a large range of
simple motor control applications. The MICROMASTER 420 can also be used for more
advanced motor control applications via its comprehensive parameter lists.
The MICROMASTER 420 can be used in both ‘stand-alone’ applications as well as being
integrated into ‘Automation Systems’.

Ambient operating conditions
Temperature
Min. operating = -10°C
Max. operating = 50°C
Humidity Range
95% Non-condensing

Altitude
If the inverter is to be installed at an altitude > 1000m, derating will be required.
(Refer to MM420 Reference Manual)

Shock
Do not drop the inverter or expose to sudden shock.

Vibration
Do not install the inverter in an area where it is likely to be exposed to constant vibration.

Electromagnetic Radiation
Do not install the inverter near sources of electromagnetic radiation.

Atmospheric Pollution
Do not install the inverter in an environment, which contains atmospheric pollutants such as dust, corrosive gases, etc.

Water
Take care to site the inverter away from potential water hazards, e.g. do not install the inverter beneath pipes that are subject to condensation. Avoid installing the inverter where excessive humidity and condensation may occur. IP54 and IP56 units offer additional protection.

Overheating
Mount the inverter vertically to ensure optimum cooling. Additional ventilation may be required for horizontal mounting.
Ensure that the inverter’s air vents are not obstructed. Allow 100 mm clearance above and below the inverter.

Mechanical Installation

THIS EQUIPMENT MUST BE GROUNDED.
♦ To ensure the safe operation of the equipment, it must be installed and
commissioned by qualified personnel in full compliance with the warnings laid down
in these operating instructions.
♦ Take particular note of the general and regional installation and safety regulations
regarding work on dangerous voltage installations (e.g. EN 50178), as well as the
relevant regulations regarding the correct use of tools and personal protective gear.
♦ The mains input, DC and motor terminals, can carry dangerous voltages even if the
inverter is inoperative; wait 5 minutes to allow the unit to discharge after switching
off before carrying out any installation work.

! Warning
♦ To ensure the safe operation of the equipment, it must be installed and
commissioned by qualified personnel in full compliance with the warnings laid down
in these operating instructions.
♦ Take particular note of the general and regional installation and safety regulations
regarding work on dangerous voltage installations (e.g. EN 50178), as well as the
relevant regulations regarding the correct use of tools and personal protective gear.
♦ The mains input, DC and motor terminals, can carry dangerous voltages even if the
inverter is inoperative; wait 5 minutes to allow the unit to discharge after switching
off before carrying out any installation work.
♦ The inverters can be installed in a side-by-side configuration, but a distance of 100
mm (3.94 inches) must be maintained if the inverters are installed on top of each
other.

General
! Warning
The inverter must always be grounded. If the inverter is not grounded correctly,
extremely dangerous conditions may arise within the inverter which could prove
potentially fatal.
Operation with ungrounded (IT) supplies
The MICROMASTER will operate from ungrounded supplies and will continue to operate
if an input phase is shorted to ground. If an output phase is shorted to ground, the
MICROMASTER will trip and indicate F0001.
On ungrounded supplies, it will be necessary to remove the ‘Y’ capacitor from the inside
of the unit and fit an output choke. The procedure for removing this capacitor is described
in Appendices E
and F.
Operation with Residual Current Device
If an RCD (also referred to as ELCB or RCCB) is fitted, the MICROMASTER inverters will
operate without nuisance tripping, provided that:
A type B RCD is used.
The trip limit of the RCD is 300mA.
The neutral of the supply is grounded.
Only one inverter is supplied from each RCD.
The output cables are less than 50m (screened) or 100m (unscreened).

Front Panels for the MICROMASTER 420

Front panels
The front panels shown below are available for use with the MICROMASTER 420
Inverters. The panel on the left is supplied with the inverter as standard and is referred to
as the Status Display Panel (SDP). The Basic Operator Panel (BOP) and Advanced
Operator Panel (AOP) are available as options.

Changing the front panel
The procedure for removing the SDP and fitting the BOP or AOP, which are available as
options, is described in Appendix A.

Commissioning with the Status Display Panel (SDP)
The SDP is supplied with your MICROMASTER 420 Inverter as
standard. This panel has two LEDs on the front, which indicate
the operational status of the inverter.
With the SDP the inverter can be used with its default settings,
for many applications. The default settings are shown in Table
3.1
The terminal layout is shown in the photograph of the Control
Terminal Connections on the inside of the back cover of this
manual.
Table 3-1 Default settings for operation using the Status Display Panel
Terminals Parameter Default Operating
Digital Input 1 5 P0701 = ‘1’ ON right
Digital Input 2 6 P0702 = ‘12’ Reverse
Digital Input 3 7 P0703 = ‘9’ Fault Reset
Output Relay 10/11 P0731 = ’52.3’ Fault Identification
