8.22 2nd 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 second motor is set. The second motor operates
when a multi-function terminal input defined as a second motor function is turned on.

Define
Set one of the multi-function input terminals (P1 – P11 ) to “26 (2nd Motor)” to
display the M2 (2nd motor group) group. An input signal sent to a multi-
function terminal set as the second 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 second motor
parameter.
• You can set the 2nd motor control mode at M2-08 (M2-Ctrl Mode). V/F PG
and Vector control modes are not supported with the 2nd motor
operation.
• PRT-50 (Stall Prevent) must be set first, before M2-28 (M2-Stall Lev)
settings can be used.
• PRT-40 (ETH Trip Sel) must be set first, before M2-29 (M2-ETH 1 min) and
M2-30 (M2-ETH Cont) settings can be used.
