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.
