This function is enabled when Drive Control Selection (3004Hex-2BHex/3009Hex-0FHex) = “0, 1, 3,
4.”
When the power supply frequency is 50 Hz, use “15: CS” and when the power supply frequency is 60
Hz, use “16: SW60.”

Switching between Inverter Operation and Commercial Power Sup-
ply Operation
• Follow the sequence diagram given below to switch among the terminals MC1 to MC3, FW and CS,
and switch from inverter operation to commercial power supply operation. When the CS terminal
turns ON, the inverter shuts of
f its output and the motor falls in a free-run state.
•
When the commercial switching signal “CS” or “SW60” is turned OFF, the operation switches to in-
verter operation from commercial power supply operation, and following the elapse of the Power In-
terruption Restart Wait Time (3008Hex-0EHex), the 50 Hz output starts when the signal during com-
mercial 50 Hz selection turns OFF, and the 60 Hz output starts when the signal during commercial
60 Hz selection turns OFF. (Start of pull-in operation)
• If the output frequency is deviating from the motor rotation speed, perform adjustment of the output
frequency during the pull-in operation based on the fall rate of restart after momentary power failure
(3008Hex-0FHex).
