Fault messages generated by the drive
Code Fault
(fieldbus code) Cause What to do
0001 OVERCURRENT
(0x2310) Output current has exceeded
internal fault limit. Check motor load.
Check acceleration time. See parameter
group
25 on page 159 .
Check motor and motor cable (including
phasing and delta/star connection).
Check that the start-up data in parameter
group
99 corresponds to the motor rating
plate.
Check that there are no power factor
correction capacitors or surge absorbers in
motor cable.
Check encoder cable (including phasing).
0002 DC OVERVOLTAGE
(0x3210) Excessive intermediate circuit
DC voltage. Check that overvoltage controller is on,
parameter
47.01 OVERVOLTAGE CTRL .
Check mains for static or transient
overvoltage.
Check braking chopper and resistor (if used).
Check deceleration time.
Use coast-to-stop function (if applicable).
Retrofit frequency converter with braking
chopper and braking resistor.
0003 DEVICE OVERTEMP
(0x4210) Measured drive temperature
has exceeded internal fault limit. Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against unit power.
0004 SHORT CIRCUIT
(0x2340) Short-circuit in motor cable(s) or
motor. Check motor and motor cable.
Check that there are no power factor
correction capacitors or surge absorbers in
motor cable.
Check the braking chopper cabling.
