 Parameter
This function is to preliminarily establish magnetic flux by applying an excitation current via the forcing
terminal [FOC] command.
This function operates if the input terminal function 066 [FOC] is assigned.
Precautions for Correct Use
• This function is effective when the IM sensorless vector control, IM zero-speed range sensor-
less vector control, or IM vector control with sensor is selected for the control mode [AA121].
• If [FOC] is assigned to the input terminal function, operation will not be accepted unless
[FOC] is turned on.
• If [FOC] is turned off during operation, the inverter will be operated according to [AA115] Stop
mode selection. If a free run occurs, restart will take place according to the setting for the
restart after free-run stop.
