(1) Pr. 501 "motor switch-over selection" = "0" (Basic Method)
The inverter-driven motor is always fixed, and the MCs between power supply and motors are turned on/off
by the output frequency to increase/decrease the number of motors run by commercial power supply.
(2) Pr. 501 "motor switch-over selection" = "1" (Alternative Method)
During operation, as in the basic method (Pr. 501 = 0), the inverter-driven motor is fixed, and the number of
motors run by commercial power supply is controlled by the output frequency. When the output is stopped by
the sleep function, the MC between inverter and motor is switched over to change the inverter-driven motor.
Note: At this time, if the sequence of starting the motors was from M1 to M2 to M3 last time, it will be from
M2 to M3 to M1 this time.
