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.

512 Auxiliary motor 1 stopping frequency 0 to 120Hz 0.01Hz 0Hz

514 Auxiliary motor 3 stopping frequency 0 to 120Hz 0.01Hz 0Hz

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.

515 Auxiliary motor start delay time 0 to 3600s 0.1s 5s

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.

503 Start waiting time 0 to 100s 0.1s 1s

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.
