Fault protection action
selection 4
00000
BIT0:Too large speed feedback error
(
Err42)
0: Coast to stop
1: Stop according to the stop mode
2: Continue to run
BIT1:Motor overspeed (Err43)
BIT2
:
Initial position fault
(
Err51)
These function parameters set action mode of the AC drive at occurrence of fault.
0: Coast to stop
The AC drive displays Err** and directly stops.
1: Stop according to the stop mode
The AC drive displays A** and stops according to stop mode. After stop, the AC drive displays Err**.
2: Continue to run
The AC drive continues to run and displays A**. The running frequency is set in F9-54.
Function Code
Parameter Name
Default
F9-54
Frequency selection for continuing
to run upon fault
Setting Range
0
0: Current running frequency
1: Frequency reference
2: Frequency upper limit
3: Frequency lower limit
4: Backup frequency upon abnormality
F9-55
Backup frequency upon fault
100.0%
0.0% to 100.0%
(100.0% corresponds to F0-10.)
These function parameters define running frequency of the AC drive when “Continue to run” is
selected at occurrence of fault.
5.6.5 Motor Overheat Protection
Function Code
Parameter Name
Default
F9-56
Type of motor temperature sensor
Setting Range
0
0: No temperature sensor
1: PT100
2: PT1000
F9-57
Motor overheat protection
threshold
110°C
0°C to 200°C
F9-58
Motor overheat pre-warning
threshold
90°C
0°C to 200°C
A motor temperature sensor can be connected to
Keyboard potentiometer
and PGND on extension
I/O card. This input is used by the drive for motor overheat protection.
When input signal reaches the value set in F9-57, the AC drive detects Err25 and acts as selected
in thousands position in F9-48. When input signal reaches the value set in F9-58, digital output ter-
minal set for function 39 becomes on.
The drive supports both PT100 and PT1000. Make sure to set sensor type correctly. You can view
motor temperature in U0-34.
