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

Define
Set one of the the multi-function input terminals (P1–P5) to 26 (2
nd
Motor) to
display M2 (2
nd
motor group) group. An input signal to a multi-function
terminal set to 2
nd
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 2
nd
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.
