Fault messages

In the event of a failure, the inverter switches off and a fault code appears on the
display.
NOTE
To reset the fault code, one of three methods listed below can be used:
1. Cycle the power to the drive.
2. Press the
3. Via Digital Input 3 (default setting)

Overvoltage
Ø Overvoltage can be caused either
by too high main supply voltage
or if motor is in regenerative
mode.
Ø Regenerative mode can be cause
by fast ramp downs or if the
motor is driven from an active
load.
Ø Main supply failed.

Diagnose & Remedy
Check the following:
1. Motor power (P0307) must correspond to
inverter power (P0206).
2. Cable length limits must not be exceeded.
3. Motor cable and motor must have no short-
circuits or earth faults
4. Motor parameters must match the motor in
use
5. Value of stator resistance (P0350) must be
correct
6. Motor must not be obstructed or overloaded
Ø Increase the ramp time
Ø Reduce the boost level
Check the following:
1. Supply voltage (P0210) must lie within limits
indicated on rating plate .
2. DC-link voltage controller must be enabled
(P1240) and parameterized properly.
3. Ramp-down time (P1121) must match inertia
of load.
4. Required braking power must lie within
specified limits.
Note
Higher inertia requires longer ramp times;
otherwise, apply braking resistor.
Check the following:
1. Supply voltage (P0210) must lie within limits
indicated on rating plate.
2. Supply must not be susceptible to temporary
failures or voltage reductions.
Check the following:
1. Fan must turn when inverter is running
2. Pulse frequency must be set to default value
3. Obstruction of air inlet and outlet points
Ambient temperature could be higher than
specified for the inverter.
Check the following:
1. Load duty cycle must lie within specified
limits.
2. Motor power (P0307) must match inverter
power (P0206)
1. Check motor data
2. Check loading on motor
3. Boost settings too high (P1310, P1311,
P1312)
4. Check parameter for motor thermal time
constant
5. Check parameter for motor I
