Warning and Alarm codes
Drive Display
Fault Code
Fault
Number
Description
Corrective Action
0
Drive is healthy and in stop condition. Motor is not energized. No enable signal is present to start
drive
1
Brake resistor over
current
Check cabling to the brake resistor and the brake resistor for short circuits.
Ensure the resistance of the brake resistor is > minimum allowed value.
2
Brake resistor thermal
overload.
Only occurs if P-34 = 1. The internal brake transistor software protection is
activated to prevent damage to the brake resistor.
Increase deceleration time in P-04, decrease load or speed
For Other Brake Resistors
Ensure the resistance of the brake resistor is >
minimum allowed value. Use an external thermal protection and set P-
34=2.
3
Instantaneous Over
current on the drive
output.
Excess load or shock
load on the motor.
Fault occurs immediately on drive enable or run command
Check the output wiring connections to the motor and the motor for short
circuits phase to phase and phase to earth.
Fault occurs during motor starting then check
•
Motor is free to rotate and there are no mechanical blockages.
•
If the motor has a brake fitted, check the brake is releasing correctly.
•
Increase the acceleration time in P-03. Reduce the motor boost voltage
P-11
Fault occurs when motor operating at constant speed
Investigate overload or malfunction.
4
Motor thermal overload
protection trip.
Drive tripped after delivering >100% of value in P-08 for a period of time
•
Ensure the correct motor nameplate current value is entered in P-08.
•
Check for correct Star or Delta wiring.
•
Check if decimal points are flashing (which indicates the output current
> P-08 value). Increase acceleration ramp (P-03) or decrease motor load.
Check the total motor cable length is within the drive specification.
Check the load mechanically to ensure that no jams, blockages or
mechanical faults exist.
5
Hardware Over Current
Check the wiring to motor for phase to phase and phase to earth short
circuits. Disconnect motor and cable. Retest. If the drive trips with no
motor connected, replace drive. Test for insulation failure.
6
Over voltage on DC
bus
Check the supply voltage is within the allowed tolerance. 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.
7
Under voltage on DC
bus
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.
8
Heat sink over
temperature
The drive is too hot. Check that ambient temperature is within the
specification. Ensure sufficient cooling air is free to circulate around the
drive.
9
Under temperature
Trip occurs when ambient temperature is less than -20°C. Temperature
must be raised over -20°C in order to start the drive.
10
Factory Default done
Press the STOP key, drive is ready to configure for particular application
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
Comms loss trip
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
Drive intended for use with a 3 phase supply has lost one input phase.
15
Output Over Current
Check for short circuits on the motor and connection cable
16
Temperature too high
Heat sink temperature too high, check adequate cooling air is provided
17
Internal memory fault.
Parameters not saved correct, defaults reloaded. Try again.
18
Analog input error
Analog input out of range. Check input current in range defined by P-16.
19
Internal memory fault
DSP fault. Press the stop key. If the fault persists, consult you supplier.
21
Motor thermistor trip
Connected motor thermistor over temperature, check wiring and motor
