Overview of MICROMASTER System Parameters

5.1.1
Default setup
The MM420 is supplied with a Status Display Panel (SDP). To change parameters it is
necessary to use a Basic Operator Panel (BOP), Advanced Operator Panel (AOP) or an
external serial interface. The MM420 is therefore delivered with the following default
settings:
Motor Parameters to suit a Siemens 4 pole motor to match the drive power and
voltage.
Setpoint control from the Analog input; 0 – 10V corresponding to 0 to 50 Hz or 0 to 60
Hz (North America).
Digital inputs:
DIN 1 Run right
DIN 2 Reverse
DIN 3 Fault Reset
DIP switch 2
Off position: European defaults (50Hz, kW etc.)
On position: North American Defaults (60Hz, hp etc.). Refer to P0100 for further
details.
DIP switch 1 is for factory use only. The switch must be in the OFF position to
operate the inverter.
Relay – Fault conditions.
Analogue Output – Output frequency

Press and hold the function button at any point in the cycle to display at any point in the
