Description
F9‑54
Frequency for
continuing to
run upon fault
0
0: Current running
frequency
1: Frequency
reference
2: Frequency upper
limit
3: Frequency lower
limit
4: Backup frequency
upon abnormality
This parameter is used to
select the frequency when the
AC drive is faulty. If a fault
occurs during the operation of
the AC drive and the fault
protection action is set to
"continue to run", the AC drive
displays A** and continues to
run at the frequency set
through F9‑54.
F9‑55
Backup
frequency
upon
abnormality
100.0% 0.0% to 100.0%
(maximum
frequency F0‑10)
This parameter is used to set
the backup frequency of the
AC drive upon fault. If a fault
occurs during the operation of
the AC drive and the fault
protection action is set to "run
at the backup frequency" (F9‑
54 is set to 4), the AC drive
displays A** and continues to
run at the backup frequency.

3.8 Monitoring
The monitoring function enables you to view the AC drive state in the LED display
area on the operating panel. You can monitor the AC drive state in the following two
ways:
1. In the stop or running state, multiple state parameters can be displayed by pressing
on the operating panel to switch over every byte of F7‑03, F7‑04 and F7‑05.
In the running state, 32 running state parameters are available. Select whether to
show a parameter corresponding to every bit according to binary F7‑03 (Running
display parameter 1) and F7‑04 (Running display parameter 2). In the stop sate, 13
stop state parameters are available. Select whether to show a parameter
