2nd Motor Operation
2nd motor operation is used when a single inverter switches its output between two
motors. Parameters for the 2
nd motor are set in the M2 parameter group. 2nd motor
operation is enabled when a digital input terminal defined as “ 2nd motor ” function is
activated.

Define
Set one of the digital input terminals (P1~P5) to 26 (2nd Motor) to
display the M2 (2nd motor) group. When activated, the inverter will
monitor and control the 2 nd motor according to the settings listed
below. An external method of switching the inverter output between
the 2 motors is required.
NOTE: When the inverter is in operation, switching of the digital input
will not be acknowledged.
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.
