Corrective Actions
1) Check cabling between drive and motor
2) Try again�
1) Check the wiring of the PID feedback�
2) Check the PID parameters settings�
n/a
1) Check the 4~20mA signal wiring (AI1 or AI2)�
2) Check if the analog signal is less than 4mA�
NOTE:
P4�63 or P4�64 must be set to 3 to enable the
Analog Loss Fault�
This fault can be temporarily bypassed by
switching Local/Remote Mode�
(The Fault is active only if the drive is actively
looking for the analog signal)�
1) Input EF (N�O�) on external terminal is closed
to GND� Output U, V, W will be turned off�
2) Press Reset after fault has been cleared�
1) When the multi-function input terminals DI1
to DI6 are set to emergency stop, the GS4
drive stops output U, V, W and the motor
coasts to stop�
2 Press RESET after fault has been cleared�
1) When the external input terminal (B.B) is
active, the GS4 drive output will be turned
off.
2) Deactivate the external input terminal
(B.B) to operate the GS4 drive again.
Keypad will be locked� Power cycle the drive
then re-enter the correct password� See P8�06
and P8�07�
The firmware version is corrupt�
Please re-download the firmware�
