For performing the contactor operation, set the [AF120] contactor control selection to 01.
The 039[CON] contactor control signal for the output terminal function and the 107[COK] contactor
check signal for the input terminal function are available.
For the contactor control, a trip occurs in the following cases.
• When the contactor check signal 107[COK] is used, [COK] is not turned on within the contactor
check time at start-up.
• When the contactor check signal 107[COK] is used, [COK] is not turned off within the contactor
check time at stop.
• When the contactor check signal 107[COK] is used, [COK] is turned off while the contactor control
signal 039[CON] is on
Precautions for Correct Use
• The contactor control requires this function because operating a contactor during the inverter
output generates a surge causing damage to the inverter.
• When an error occurs in the contactor sequence, the inverter trips at [E110].
