Motor Operation
The 2nd motor operation is used when a single inverter switch operates two motors.
Using the 2nd motor operation, a parameter for the 2nd motor is set. The 2nd motor is
operated when a multi-function terminal input defined as a 2nd motor function is
turned on.

Define
Set one of the multi-function input terminals to 26 (2nd Motor) to
display M2 (2nd motor group) group. An input signal to a multi-function
terminal set to 2nd motor will operate the motor according to the code
settings listed below. However, if the inverter is in operation, input
signals to the multi-function terminals will not read as a 2nd motor
parameter.
Pr.50 (Stall Prevent) must be set first, before M2.28 (M2-Stall Lev)
settings can be used. Also, Pr.40 (ETH Trip Sel) must be set first,
before M2.29 (M2-ETH 1min) and M2.30 (M2.ETH Cont) settings.
