Operation of protective functions during emergency drive
●
Operation of protective functions during emergency drive is as follows.
While the switchover to the commercial power supply operation during emergency drive opera-
tion is enabled, when the same protective function is activated twice consecutively, the retry is
attempted up to twice.
●
The fault output during emergency drive operation is as follows.
Input signal operation
●
During emergency drive operation in the fixed frequency mode or in the PID control mode, input
signals unrelated to the emergency drive become invalid with some exceptions.
●
The table below shows functions of the signals that do not become invalid during emergency
drive operation in the fixed frequency mode or in the PID control mode.

Description
Positive logic Negative logic
ALM 99 199
Turns ON at the occurrence of a fault that causes the above-mentioned
"retry" or "output shutoff" during emergency drive operation.
ALM3 66 166
Output when a fault occurs during emergency drive operation.
During emergency drive operation, if a fault that does not activate any
protective function occurs, the signal turns ON for 3 s and then turns
OFF.
