Diagnostics
Table of faults
Faults Cause / solution
DC link voltage too low, supply sys-
tem off detected
(motor stops, without fault code)
Check power cables and supply voltage for interruption. Motor restarts automatically as soon
as the supply voltage reaches normal values.
Fault code 01
Overcurrent of output stage
Short circuit of inverter output.
Check the connection between inverter output and motor for short circuit.
Reset the fault by switching off the 24 V
DC
supply voltage or use MOVILINK
®
.
Fault code 06
Phase fault
(The fault can only be recognized with
a load on the drive)
Check power cables for phase fault. Reset the fault by switching off the 24 V
DC
supply voltage
or use MOVILINK
®
.
Fault code 07
DC link voltage too high
A Ramp time too short → Increase ramp time.
B Faulty connection between brake coil and braking resistor.
→ Check the connection between braking resistor and brake coil. Correct, if necessary.
C Incorrect internal resistance of brake coil/braking resistor
→ Check the internal resistance of the brake coil/braking resistor
(see the section "Technical Data").
D Thermal overload in braking resistor → Wrong size of braking resistor selected.
Reset the fault by switching off the 24 V
DC
supply voltage or use MOVILINK
®
.
Fault code 08
Speed monitoring
Speed monitoring tripped, load of drive is too high → Reduce the load of the drive.
Reset the fault by switching off the 24 V
DC
supply voltage or use MOVILINK
®
.
Fault code 11
Thermal overload of the output
stage or internal unit fault
• Clean the heat sink
• Reduce the ambient temperature
• Prevent heat accumulation
• Reduce the load on the drive
Reset the fault by switching off the 24 V
DC
supply voltage or use MOVILINK
®
.
Fault code 17 to 24, 37
CPU fault
Reset the fault by switching off the 24 V
DC
supply voltage or use MOVILINK
®
.
Fault code 25, 94
EEPROM error
Reset the fault by switching off the 24 V
DC
supply voltage or use MOVILINK
®
.
Fault code 84
Thermal overload of motor
• With shouldered assembly of the MOVIMOT
®
inverter, set DIP switch S3/1 to "ON".
• For combinations of "MOVIMOT
®
and motor with one lower power increment," check the
position of DIP switch S3/2.
• Reduce the ambient temperature
• Prevent heat accumulation
• Reduce the load on the motor
• Increasing the speed
• Check the combination of the drive and MOVIMOT
®
frequency inverter if the fault is sig-
naled shortly after the first release.
Reset the fault by switching off the 24 V
DC
supply voltage or use MOVILINK
®
.
Fault code 89
Thermal overload of brake coil or
brake coil defective
• Extend the set ramp time
• Brake inspection (see the section "Inspection and Maintenance")
• Contact SEW service
• If the fault should occur shortly after the initial enable, check the combination of drive
(brake coil) and MOVIMOT
®
frequency inverter.
• For combinations of "MOVIMOT
®
and motor with one lower power increment," check the
position of DIP switch S3/2.
Reset the fault by switching off the 24 V
DC
supply voltage or use MOVILINK
