Drive OK |
Cause:
Drive is functioning normally.
Remedy:
None required.
|
1
Over Voltage on the D.C. Link |
Cause:
Voltage on the DC link has exceeded limits.
Remedy:
- Check the three-phase power line.
- Check the break circuit and the braking resistor.
|
2
Under Voltage on the D.C. Link |
Cause:
Voltage on the DC link is too low.
Remedy:
- Check the three-phase power line.
|
3
Over current |
Cause:
Excessive current detected.
Remedy:
- Check for any mechanical blockage and make sure the motor is the appropriate size for its current use.
- Check the motor connections and for any phase-phase or phase-ground short-circuits.
- Check the machine speed and the service cycle.
- Make sure a line trap isn’t connected to the motor!
|
4
Resolver |
Cause:
Feedback signal issue.
Remedy:
- Check the connections of the resolver and the connectors on both sides (drive-motor).
|
5
PTC motor alarm |
Cause:
Motor overheating or sensor fault.
Remedy:
- Check the PTC connection cable.
- If the alarm persists, disable the drive, remove power from the motor and de-energize the drive (24VDC).
- Remove the PTC connector from the drive, short-circuit the PTC (connecting PTC+ and PTC-) on the same drive terminal block.
- Supply power to the drive (24VDC). If the alarm persists, either the drive is in fault state, or the PTC on the motor is in fault state.
- (At the end of the test, remove the PTC short-circuiting connection).
|
6
Drive Over Temperature |
Cause:
Drive unit is overheating.
Remedy:
- Check the cooling fans and for any restrictions to air flow.
- Check the breaking cycle.
- Check the environmental temperature of the electrical control panel where the drive is installed, as well as the external room temperature.
|
7
External alarm |
Cause:
Triggered by application (see the pico-PLC).
Remedy:
- Check application specific pico-PLC logic.
|
8
Auxiliary alarm |
Cause:
Triggered by application (see the pico-PLC).
Remedy:
- Check application specific pico-PLC logic.
|
10
check sum PLC |
Cause:
PLC data corruption or error.
Remedy:
- Set the default of the drive, save and restart the drive.
- Reprogramming the drive.
|
11
check sum parameters |
Cause:
Parameter data corruption.
Remedy:
- Set the default of the drive, save and restart the drive.
- Reprogramming the drive.
|
14
Brake overload |
Cause:
Braking resistance use overload.
Remedy:
- Check braking cycle and resistor sizing.
|
15
Default parameter |
Cause:
Parameter error.
Remedy:
- Reprogramming the drive, save and restart the drive.
|
17
Calibration error |
Cause:
Calibration data invalid.
Remedy:
- Contact technical support or retry calibration if applicable.
|
22
Ambient over temperature |
Cause:
Ambient temperature too high.
Remedy:
- Check the temperature of the environment.
|
24
Braking transistor protection |
Cause:
Short-circuit braking resistance.
Remedy:
- If an external braking resistor is connected to the drive, check the resistor status and wiring.
- Can be only reset at the next power on.
|
25
Feedback speed error |
Cause:
Issue with speed feedback signal.
Remedy:
- Check the selection of feedback and the connection.
|
….
Limitation of current (I²T) |
Cause:
The drive goes in I²T mode due to an overload (it required more current that was available).
Remedy:
- Check the cables between motor and SLVD-N (there should be no inverted phases).
- Take special care with motors with terminals rather than the connector: it’s easy to make a mistake.
- Adhere strictly to the wiring diagrams.
- Check Power limit active (if 1-phase supply: b94.15=1).
