You can set the output frequency of the inverter-operated motor at which the commercial power supply
operation motors start. When the output frequency higher than the preset value continues for longer than
the time set in Pr. 515, the commercial power supply motors start. In this case, the starting sequence
depends on the pattern in Pr. 501. Here, the Pr. 509 value means the set value at which the commercial
power supply motors start when the number of commercial power supply motors running is 0.

You can set the output frequency of the inverter-operated motor at which the commercial power supply
operation motors stop. When the output frequency lower than the preset value continues for longer than the
time set in Pr. 516, the commercial power supply motors stop. In this case, the stopping sequence depends
on the pattern in Pr. 501. Here, the Pr. 512 value means the set value at which the commercial power
supply motors stop when the number of commercial power supply motors running is 1.

You can set the delay time until the auxiliary motor is started. The auxiliary motor starts actually when the
time set in Pr. 515 elapses after the output frequency of the inverter operation motor has risen to or above
the value set in any of Pr. 509 to Pr. 511.

You can set the delay time until the auxiliary motor is stopped. The auxiliary motor stops actually when the
time set in Pr. 516 elapses after the output frequency of the inverter operation motor has dropped to or
below the value set in any of Pr. 512 to Pr. 514.

You can set the MC switching interlock time (e.g. time from when RI01 turns off until R01 turns on) when
Pr. 501 = 2.

502 MC switching interlock time 0 to 100s 0.1s 1s
#
You can set the time from MC switch-over to a start (time from when RI01 turns off and RI02 turns on until
inverter output starts) when Pr. 501 = 2. Set this time a little longer than the MC switching time.

You can set the deceleration time until the output frequency varies by the decrement = Pr. 509 to Pr. 512
(for M2) if a motor connection occurs under advanced PID control. When the setting is 9999, the output
frequency is not forcibly changed.
