Fault tracing
Cause
Output current has exceeded
internal fault limit.
Excessive intermediate circuit
DC voltage.
Measured drive temperature
has exceeded internal fault limit.
Short-circuit in motor cable(s) or
motor.
Intermediate circuit DC voltage
is not sufficient due to missing
mains phase, blown fuse or
rectifier bridge internal fault.
Drive has detected load
unbalance typically due to earth
fault in motor or motor cable.
46.05
Fan is not able to rotate freely or
fan is disconnected. Fan
operation is monitored by
measuring fan current.
What to do
Check motor load.
Check acceleration time. See parameter
group 25 SPEED REF RAMP
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).
Check that overvoltage controller is on,
parameter 47.01 OVERVOLTAGE
Check mains for static or transient
overvoltage.
Check brake chopper and resistor (if used).
Check deceleration time.
Use coast-to-stop function (if applicable).
Retrofit frequency converter with brake
chopper and brake resistor.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against unit power.
Check motor and motor cable.
Check there are no power factor correction
capacitors or surge absorbers in motor cable.
Check mains supply and fuses.
Check there are no power factor correction
capacitors or surge absorbers in motor cable.
Check that there is no earth fault in motor or
motor cables:
- measure insulation resistances of motor and
motor cable.
If no earth fault can be detected, contact your
local ABB representative.
Check fan operation and connection.
