What causes FB PID feedback loss error on gefran VDI100-3110-KBX-4?
If your Gefran Inverter displays an FB (PID Feedback Loss) error, it could be due to a broken feedback signal wire; check the feedback wiring. It could also be that the feedback sensor is broken, so replace the feedback sensor.
What does CE communication error mean on my gefran VDI100-3110-KBX-4?
If your Gefran Inverter displays a CE (Communication Error), it could be due to a connection loss or broken wire, so check the connection. It could also be that the host stopped communicating, so check the host computer/software.
Why does my gefran VDI100-3110-KBX-4 show a DEV Speed deviation error?
If your Gefran Inverter displays a DEV (Speed Deviation) error, it could be due to several reasons. The load might be too heavy, so check the load. The mechanical brake might be active, preventing the motor from turning, so make sure the brake is released. There could be a PG wiring error, so check the PG wiring. The PG parameters might be set incorrectly, so check PG parameters 20-23/20-24. Finally, the acceleration/deceleration time might be set too short, so increase the acceleration/deceleration time.
Why does my gefran VDI100-3110-KBX-4 Inverter show an OV Over voltage error?
If the Gefran Inverter displays an OV (Over Voltage) error, it could be due to several reasons. The deceleration time might be set too short, causing regenerative energy to flow back from the motor. Try increasing the deceleration time. Alternatively, the input voltage to the inverter may be too high; in this case, reduce the input voltage or install an AC line reactor. Also, remove any power factor correction capacitors that may be in use. In some cases, excessive braking load, defective braking transistor/resistor, or incorrect speed search parameters can cause this, so use a dynamic braking unit, replace the braking transistor/resistor, or adjust the speed search parameters, respectively.
What does OCd over current mean on gefran VDI100-3110-KBX-4?
If your Gefran Inverter displays an OCd (Over Current) error, it's likely because the deceleration time is too short. To resolve this, set a longer acceleration time.
What causes an OCC over current error on a Gefran Inverter?
If your Gefran Inverter displays an OCC (Over Current) error, it might be due to an instantaneous change of load; in this case, change to a bigger size of inverter. It could also be due to an instantaneous change of current; try adding a reactor to the power source.
What to do if my gefran VDI100-3110-KBX-4 shows an OPL output phase loss error?
If your Gefran Inverter displays an OPL (Output Phase Loss) error, it could be because the wiring is loose in the inverter output terminal; check the output wiring and tighten the screws. It could also be that the motor's rated current is less than 10% of the inverter's rated current; check the motor and inverter ratings.
What does IPL input phase loss mean on my Gefran Inverter?
If your Gefran Inverter displays an IPL (Input Phase Loss) error, it could be due to a few reasons. The wiring might be loose in the inverter input terminal, so check the input wiring and tighten the screws. There might be a momentary power loss, so check the power supply. Input voltage imbalance could also cause this, so check the power supply.
How to fix OH1 Heatsink overheat error on gefran VDI100-3110-KBX-4?
If your Gefran Inverter displays an OH1 (Heatsink Overheat) error, it could be due to several reasons. The ambient temperature might be too high, so install a fan or AC to cool the surroundings. The cooling fan might have failed, so replace the cooling fan. The carrier frequency might be set too high, so reduce the carrier frequency. Also, the load might be too heavy, so reduce the load and measure the output current.
What does SC short circuit mean on gefran VDI100-3110-KBX-4?
An SC (Short Circuit) error on your Gefran Inverter can be caused by a short circuit or ground fault; check the motor wiring. It could also indicate a damaged motor (insulation); in that case, disconnect the motor and try running the inverter. Wire damage or deterioration can also cause this error; disconnect the motor and try running the inverter.
