Chapter 7 Fault Detection and Diagnostics

7.1 Faults and Solutions

If a fault or alarm happened, keypad will display the fault or alarm at once. Fault displays "Er"+fault
code and the alarm displays "AL"+fault code. You can use the STOP/RST key or X terminal reset
function to reset the fault or alarm.
These parameters of A1.00～A1.35 are used to record the fault code and drive status of the recent
three faults of the drive.

Table 7- 1 LED Fault and display
Possible Causes
The acceleration time is too short.
The inertia of the load is too large.
The output circuit is short
circuited.
The input voltage is too high.
The deceleration time is too short.
The inertia of the load is too large.
The output circuit is short
circuited.
The input voltage is too high.
the regulator parameters are
improper In SVC control mode.
The motor parameters are
improper.
The load fluctuation is too big
The input voltage is too high.
The output circuit is short
circuited.
the regulator parameters are
improper In SVC control mode.
Motor to ground is short circuit.
The input voltage is too high.
Start again quickly when motor in
high speed rotating.
