Select motor 2 / motor 1 -- M2/M1
(Function code data = 12)
Turning this terminal command ON switches from the 1st motor to the 2nd one. Switching is
possible only when the inverter is stopped. Upon completion of switching, the digital
terminal output "Switched to motor 2" SWM2 (assigned to any of terminals [Y1] and
[30A/B/C]) turns ON.
If no M2/M1 terminal command is assigned, the 1st motor is selected by default.

Switching between the 1st and 2nd motors automatically switches applicable function codes
as listed below. The inverter runs the motor with those codes that should be properly
configured.
