Description
Suggested Remedy
00
No Fault
Not required
01
Brake channel over current
Check external brake resistor condition and connection wiring
02
Brake resistor overload
The drive has tripped to prevent damage to the brake resistor
03
Output Over Current
Instantaneous Over current on the drive output. Excess load or shock load on the motor.
Note: Following a trip, the drive cannot be immediately reset. A delay time is inbuilt, which allows the
power components of the drive time to recover to avoid damage.
04
Motor Thermal Overload (I2t)
The drive has tripped after delivering >100% of value in P-08 for a period of time to prevent damage to
the motor.
05
Power stage trip
Check for short circuits on the motor and connection cable
06
Over voltage on DC bus
Check the supply voltage is within the allowed tolerance for the drive. If the fault occurs on deceleration
or stopping, increase the deceleration time in P-04 or install a suitable brake resistor and activate the
dynamic braking function with P-34
07
Under voltage on DC bus
The incoming supply voltage is too low. This trip occurs routinely when power is removed from the drive.
If it occurs during running, check the incoming power supply voltage and all components in the power
feed line to the drive.
08
Heatsink over temperature
The drive is too hot. Check the ambient temperature around the drive is within the drive specification.
Ensure sufficient cooling air is free to circulate around the drive.
Increase the panel ventilation if required. Ensure sufficient cooling air can enter the drive, and that the
bottom entry and top exit vents are not blocked or obstructed.
09
Under temperature
Trip occurs when ambient temperature is less than -10°C. Temperature must be raised over -10°C in
order to start the drive.
10
Factory Default parameters loaded
11
External trip
E-trip requested on digital input 3. Normally closed contact has opened for some reason. If motor
thermistor is connected check if the motor is too hot.
12
Optibus comms loss
Check communication link between drive and external devices. Make sure each drive in the network has
its unique address.
13
DC bus ripple too high
Check incoming supply phases are all present and balanced
14
Input phase loss trip
Check incoming power supply phases are present and balanced.
15
Output Over Current
Check for short circuits on the motor and connection cable
Note: Following a trip, the drive cannot be immediately reset. A delay time is inbuilt, which allows the
power components of the drive time to recover to avoid damage.
16
Faulty thermistor on heatsink
17
Internal memory fault. (IO)
Press the stop key. If the fault persists, consult you supplier.
18
4-20mA Signal Lost
Check the analog input connection(s).
19
Internal memory fault. (DSP)
Press the stop key. If the fault persists, consult you supplier.
21
Motor PTC thermistor trip
Connected motor thermistor over temperature, check wiring connections and motor
22
Cooling Fan Fault (IP66 only)
Check / replace the cooling fan
23
Drive internal temperature too high Drive ambient temperature too high, check adequate cooling air is provided
26
Output Fault
Indicates a fault on the output of the drive, such as one phase missing, motor phase currents not
balanced. Check the motor and connections.
40
Autotune Fault
The motor parameters measured through the autotune are not correct.
Check the motor cable and connections for continuity
Check all three phases of the motor are present and balanced
41
42
43
44
50
Modbus comms loss fault
Check the incoming Modbus RTU connection cable
Check that at least one register is being polled cyclically within the timeout limit set in P-36 Index 3
51
CANopen comms loss trip
Check the incoming CAN connection cable
Check that cyclic communications take place within the timeout limit set in P-36 Index 3
