 Emergency drive operation selection (Pr.523, Pr.524)
• Use Pr.523 Emergency drive mode selection to select the emergency drive operation. Set a value in the
hundreds place to select the operation when a valid protective function is activated (critical fault) during
emergency drive. Set values in the ones and tens places to select the operation method.

*1 Under PM motor control, the operation is not switched over to the commercial power supply operation and the output is shut off.
NOTE
• The operation is automatically switched from the PU operation mode or External/PU combined operation mode to
the External operation mode when the emergency drive is activated in the fixed frequency mode or in the PID control
mode.
Output shutoff at a critical fault occurrence.
Retry operation at a critical fault occurrence. (Output
shutoff at the occurrence of a fault for which retry is not

The output is shut off when a critical fault for which retry
is not permitted occurs, or the retry count is exceeded.

While Pr.515 = "9999", the operation is switched over to
the commercial power supply operation when the retry

The operation is switched over to the commercial power
supply operation when a critical fault occurs.
The operation is performed with the same set frequency
and by the same starting command as those in the
normal operation.
Use this mode to avoid output shutoff due to a fault.
The operation is forcibly performed with the frequency
