(H) Protective function parameter Parameters
5 - 166
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.
Under PM motor control, the operation is not switched over to the commercial power supply
operation the output is shut off.
Retry operation during emergency drive (Pr. 515, Pr. 514)
●
Set the retry operation during emergency drive operation. Use Pr. 515 "Emergency drive dedicat-
ed retry count" to set the retry count, and use Pr. 514 "Emergency drive dedicated retry waiting
time" to set the retry waiting time.
●
The ALM signal output conditions depend on the Pr. 67 "Number of retries at fault occurrence"
setting. (Refer to page 5-159.)
●
For the protective functions (critical faults) for which a retry is performed during emergency drive
operation, refer to page 5-169.
Pr. 523 setting Emergency drive operation mode Description
1 Output shutoff mode Output shutoff at a critical fault occurrence.
2 Retry / output shutoff mode
Retry operation at a critical fault occurrence. (Output
shutoff at the occurrence of a fault for which retry is not
permitted.)
The output is shut off when a critical fault for which retry is
not permitted occurs, or the retry count is exceeded.
3
Retry / commercial mode
Retry operation at a critical fault occurrence. (Electronic
bypass at the occurrence of a fault for which retry is not
permitted.)
The operation is switched over to the commercial power
supply operation 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
count reaches 200.
4
Commercial mode
The operation is switched over to the commercial power
supply operation when a critical fault occurs.
00 Normal operation mode
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.
11
Fixed
frequency
mode
Forward rotation The operation is forcibly performed with the frequency
set in Pr. 524.
Even when the motor is stopped, the operation is started
by the emergency drive execution.
12 Reverse rotation
21
PID control
mode
Forward rotation The operation is performed under PID control using the
Pr. 524 setting as a set point. The measured values are
input in the method set in Pr. 128.
22 Reverse rotation
23
Forward rotation
(Second PID measured
value input)
The operation is performed under PID control using the
Pr. 524 setting as a set point. The measured values are
input in the method set in Pr. 753.
24
Reverse rotation
(Second PID measured
value input)
