Chapter 5 Troubleshooting and maintenance
5.1. Error display and corrective action
5.1.1. Faults which can not be recovered manually
1. Faults which can not be recovered manually
Display Fault Cause Corrective action
Voltage too high
when stopped
Detection circuit malfunction Return the inverter
Voltage too low
when stopped
1. Power voltage too low
2. Pre-charge resistor or fuse
burnt out.
3. Detection circuit malfunction
1. Check if the power voltage is
correct
2. Replace the pre-charge resistor
or the fuse
3. Return the inverter
The inverter is
overheated
when stopped
1. Detection circuit malfunction
2. Ambient temperature too high
or bad ventilation
1. Return the inverter
2. Improve ventilation
conditions
Current Sensor
detection error
Current sensor error or circuit
malfunction
Return the inverter
EEPROM
problem
Faulty EEPROM Replace EEPROM
2. Faults which can be recovered manually and automatically
Display Fault Cause Corrective Action
Over current at
start
1. Short circuit between the
motor coil and the case
2. Short circuit between motor
coil and ground
3. the IGBT module damaged
1. Inspect the motor
2. Inspect the wiring
3. Replace the transistor module
Over-current at
deceleration
The preset deceleration time is
too short.
Set a longer deceleration time
Over-current at
acceleration
1. Acceleration time too short
2. The capacity of the
motor exceeds the capacity of
the inverter
3. Short circuit between
the motor coil and the case
4. Short circuit between
motor wiring and ground
5. the IGBT module damaged
1. Set a longer acceleration time
2. Replace inverter with one that
has the same rating as that of the
motor
3. Check the motor
4. Check the wiring
5. Replace the IGBT module
Over-current at
fixed speed
1. Transient load change
2. Transient power change
1.Increase the capacity of the
inverter
2.Repeat parameter auto tuning
(06-05= 1)
3.Reduce stator resistance
(06-06) if the above actions are
ineffective
Excessive
Voltage during
operation/
deceleration
1. Deceleration time setting too
short or excessive load inertia
2. Power voltage varies widel
y
(fluctuates)
1. Set a longer deceleration time
2. Add a brake resistor or brake
module
3. Add a reactor at the power input
side
4. Increase inverter capacity
Unacceptable
CPU interrupt
External noise interference
Return unit if this happens
regularly
