If the interference detection function worked to make the motor retract in the direction of no
interference, operation in a regular manner is enabled after this signal is turned off.
In position control mode (pulse operation) and speed control mode, however, the operations in the
following table must be performed to return to the regular operation:

supply
This setting ensures compatibility with the SEMI F47 standard.
By setting this parameter to “1: Enable”, the control power undervoltage alarm level and main power
shutoff detection time will be changed, allowing operation stoppages due to alarms to be circumvented,
and operation to be continued.
• The main power supply is a three-phase power supply, and is compatible with no loads and light
loads. This parameter is not applicable for use with single-phase power supplies.
• When set to "1: Enable", the settings of PA2_68 (Main power shutoff detection time) are disabled.
• Be sure to carry out a detailed check for the SEMI F47 standard on the actual customer ’ s equipment.
