What to do in case of a communication error during parameter transfer on a gefran ADL550 Inverter?
If you experience a communication error during the transfer of parameters from the drive to the memory of the keypad on your Gefran Inverter, recover a set of parameters from a compatible drive (model and size).
How to fix Gefran Inverter DC link overvoltage alarm?
If your Gefran Inverter displays a DC link overvoltage alarm because the energy recovered from the voltage arriving at the drive power section is too high, you can extend the deceleration ramp. Alternatively, use a braking resistor connected to the specific terminals to dissipate the energy recuperation.
What causes a motor overtemperature alarm on a Gefran Inverter?
A motor overtemperature alarm on your Gefran Inverter can be triggered by several factors: * A load cycle that is too heavy. * The motor being installed in an environment with a high ambient temperature. * A faulty motor blower fan. * Excessive load at slow speeds if the motor lacks a blower. * Operating the motor below its rated frequency. To address this, change the processing cycle or use a cooling fan to cool the motor.
What to do if gefran ADL550 Inverter shows an overcurrent alarm?
If your Gefran Inverter is showing an instantaneous overcurrent protection intervention alarm, it might be caused by incorrect settings of the current regulator parameters. You should check the current regulator parameters (menu 12.3) and inspect the wiring towards the motor.
How do I troubleshoot a ground fault alarm on a Gefran Inverter?
To troubleshoot a ground fault alarm (ground short circuit alarm) on your Gefran Inverter, check the drive and motor wiring. Also, ensure that the motor is not grounded.
What should I do if there is an error during loading of the parameter database on my gefran ADL550 Inverter?
If you encounter an error during loading of the parameter database saved in the Flash memory of the MDPLC application on your Gefran Inverter because the database saved is not valid, set the parameters to the desired value and run Save parameter.
What to do if there is a safety function issue on a gefran ADL550 Inverter?
If you encounter a safety function issue on your Gefran Inverter, switch the drive off and then back on. If the error persists, contact the technical service centre.
What if my gefran ADL550 Inverter displays a message during power card recognition?
If your Gefran Inverter displays a message during recognition of power cards, and it's not possible to drive the motor, it may be because the power card is configured for a drive that is incompatible with the regulation card, the configuration of the power card is not compatible with the regulation card, or the configuration required is not available on the power card. Download the correct configuration on the power card.
What does a speed reference loss alarm mean on a gefran ADL550 Inverter?
A speed reference loss alarm on your Gefran Inverter means the difference between the speed regulator reference and the actual motor speed is more than 100 rpm, usually because the drive is in the current limit condition. Check that the load is not excessive.
How to resolve a braking resistor overload alarm on a gefran ADL550 Inverter?
A braking resistor overload alarm on your Gefran Inverter means the current absorbed by the resistor is greater than the rated current. Check the size and condition of the braking resistor.
