[Recovering normal operation]
If the interference detection function is triggered and the servomotor has retreated in the direction
of no interference, normal operation will be possible after this signal turns OFF.
When in position control mode (pulse train operation) or speed control mode, however, the
operations indicated in the following table will be required to recover normal operation.

compatible function
This setting ensures compatibility with the SEMI F47 standard.
By setting this parameter to "1: Enable", the control power undervoltage alarm level and PA2_68 (Main
power shutoff detection time) will be automatically 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.
• Be sure to carry out a detailed check for the SEMI F47 standard on the actual customer's equipment.
