If your Megmeet DC Drives has poor auto-tuning, it could be because the nameplate parameters of the motor are incorrect, so set the parameters properly according to the motor nameplate. Also, if reverse running is prohibited, cancel the reverse running prohibition when reverse rotating auto-tuning is performed. Check motor wiring if auto-tuning overtime.
What to do if my Megmeet MV600 DC Drives shows constant speed over-current?
If your Megmeet DC Drives experiences constant speed over-current, it could be due to several reasons: the acceleration/deceleration time being too short (lengthen the acceleration/deceleration time appropriately); a sudden load change or abnormal load (check the load); low grid voltage (check the input power supply); encoder fault when PG is running (check the encoder and its wiring); or the drive power being too low (adopt the drive with high power class).
What to do if my Megmeet MV600 shows deceleration over-current?
If your Megmeet DC Drives is showing deceleration over-current, it might be because the deceleration time is too short (lengthen the deceleration time). Alternatively, there may be potential energy load or a large load inertial torque (use additionally appropriate dynamic braking components). It could also be due to an encoder fault while PG is running (check the encoder and its wiring), or the drive power might be too low (adopt the drive with high power class).
What to do if my Megmeet MV600 shows acceleration over-voltage?
If your Megmeet DC Drives shows acceleration over-voltage, it could be due to abnormal input voltage (check the input power supply). It may also be caused by the acceleration time being too short (lengthen the acceleration time appropriately), or restarting the rotating motor after an instantaneous stop (set the start mode P08.00 as the speed tracking restart function).
What to do if Megmeet MV600 is overloaded?
If your Megmeet DC Drives is overloaded, it could be due to incorrect motor parameters (perform the parameter auto-tuning of the motor), an excessively large load (adopt the drive with higher power), an excessive DC braking amount (reduce the DC braking current and lengthen the braking time), restarting the rotating motor after an instantaneous stop (set the start mode P08.00 as the speed tracking restart function), acceleration time being too short (lengthen the acceleration time), low grid voltage (check the grid voltage), or an improper V/F curve (adjust V/F curve and torque increase).
What should I do if my Megmeet DC Drives has closed loop feedback loss?
If your Megmeet DC Drives has closed loop feedback loss, it could be due to improperly set parameters for feedback loss (modify the P14.26 setting). It may also be caused by a feedback wire-break (rewiring) or the reference of the closed loop feedback value being too low (see the P14.01 setting and increase the feedback reference).
What to do if my Megmeet MV600 has abnormal remote serial port?
If your Megmeet DC Drives has an abnormal remote serial port, it might be because the baud rate is set improperly, so set the baud rate properly. In case of serial port communication error, reset by pressing the STOP/RESET key.
What to do if Megmeet DC Drives experiences system interference?
If your Megmeet DC Drives experiences system interference, and is severely interfered, reset by pressing the STOP/RESET key or install a power filter to the input side of the power supply.
Why is my Megmeet DC Drives inverter module overheating?
If your Megmeet DC Drives inverter module is overheating, it could be due to a high ambient temperature (lower the ambient temperature) or a blocked duct (clean the duct).
What does it mean if my Megmeet DC Drives shows 'Input side phase loss'?
If your Megmeet DC Drives displays 'Input side phase loss', it indicates that there is phase loss in input R.S.T. To resolve this, check the installation wiring and the input voltage.
