To address insufficient motor torque with your Inovance Controller, check whether the torque upper limit is set too low. If it is, increase the setting of F2-10 (digital setting of torque upper limit in speed control mode) in the speed control mode, or increase the torque reference (A0-03) in the torque control mode.
What to do if Inovance MD500 detects overload or overcurrent during motor running?
If your Inovance Controller is showing an overload or overcurrent during motor running, set the motor parameters F1-01 to F1-05 according to the motor nameplate. Also, select a proper motor auto-tuning mode by setting F1-37 and perform motor auto-tuning. If possible, select dynamic auto-tuning.
What causes IGBT overheat in Inovance Controller and how to fix it?
IGBT overheat in your Inovance Controller can be caused by several factors. The ambient temperature may be too high, so lower it. Other potential solutions include cleaning the ventilation, replacing the cooling fan if it's damaged, replacing the damaged thermally sensitive resistor, or as a last resort, replacing the AC Drive IGBT.
What to do if Inovance MD500 Controller shows motor overload?
If the Inovance Controller indicates a motor overload, it might be because the load is too heavy, or the motor has a locked rotor. Try reducing the load or inspecting the motor and mechanical components. If the issue persists, consider using a drive with a larger power class.
What to do if Inovance MD500 Controller detects overload or overcurrent during motor start?
If your Inovance Controller detects an overload or overcurrent fault during motor start, set F1-27, F1-28 and F1-30 correctly.
Why is there a very large current during running with the Inovance MD500?
If you're experiencing a very large current during running with your Inovance Controller, ensure that the rated motor voltage (F1-02) and rated motor frequency (F1-04) are set correctly. Also, gradually decrease the setting of F3-01 (torque boost) by 0.5%.
What causes input phase loss in Inovance MD500 Controller?
If you are experiencing input phase loss with your Inovance Controller, eliminate faults in external circuitry.
How to troubleshoot motor auto-tuning fault in Inovance MD500?
To troubleshoot a motor auto-tuning fault in your Inovance Controller, set motor parameters correctly according to nameplate. Also, check the cable connecting AC drive and motor.
How to improve torque or speed response for Inovance MD500 at speeds above 5 Hz?
To improve torque or speed response and address motor oscillation at speeds above 5 Hz on your Inovance Controller: if motor torque and speed response are too slow, increase the setting of F2-03 (speed loop proportional gain) by 10 gradually or decrease the setting of F2-04 (speed loop integral time) by 0.05 gradually. If motor oscillation occurs, decrease F2-03 and increase F2-04.
What to do if Inovance MD500 detects overcurrent when heavy load is suddenly added?
If the Inovance Controller detects overcurrent when a heavy load is suddenly added or during acceleration, increase the setting of F3-20 (overcurrent stall gain, default is 20) by 10 gradually, up to a maximum of 100. Also, decrease the setting of F3-18 (overcurrent stall actuating current, default is 150%) by 10% gradually, down to a minimum of 50%.
