What to do if my Megmeet MV600 DC Drives shows acceleration over-current?
- B
  Briana CoxAug 22, 2025
  If your Megmeet DC Drives shows acceleration over-current, the possible causes include: the acceleration time being too short (lengthen the acceleration time); incorrect motor parameters (perform the parameter auto-tuning of the motor); restarting the rotating motor after an instantaneous stop (set the start mode P08.00 as the speed tracking restart function); PG fault during running (check the PG and its wiring); insufficient drive power (adopt a drive with a higher power class); or an improper V/F curve (adjust the V/F curve setting and the manual torque increase).

What does it mean if my Megmeet DC Drives shows 'Input side phase loss'?
- B
  Beth HardySep 3, 2025
  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.

What causes power module protection in Megmeet MV600 and how to resolve it?
- M
  Mary OliverSep 2, 2025
  Power module protection in Megmeet DC Drives can be triggered by several factors. These include: * Interphase short circuit or grounding short circuit in output three phases (rewiring and check if the motor insulation is good). * Instantaneous over-current of the drive (see the over-current solutions). * Blocked duct or damaged fan (unblock the duct or replace the fan). * High ambient temperature (lower the ambient temperature). * Loose wirings or plug-in units of the control board (check them and rewiring). * Abnormal current waveform caused by output phase loss (check the wiring).

What to do if Megmeet DC Drives shows constant speed over-voltage?

  Ashley EricksonAug 31, 2025
  If your Megmeet DC Drives shows constant speed over-voltage, it might be because the ASR parameter setting is improper when the vector control functions (see the ASR parameter setting of Group P05). It could also be due to the acceleration/deceleration time being too short (lengthen the acceleration/deceleration time appropriately), abnormal input voltage (check the input power supply), the input voltage fluctuating abnormally (install the input reactor), or large load inertia (adopt dynamic braking components).

What to do if my Megmeet DC Drives motor is overloaded?
- S
  Shannon SteeleAug 30, 2025
  If your Megmeet DC Drives motor is overloaded, it may be due to the motor overload protection factor setting being incorrect (set the overload protection factor of motor correctly). It could also be caused by the motor being blocked or a sudden, large change in load (check the load). If a universal motor runs at low speed for a long time with a heavy load, and long-term low-speed running is required, a special motor should be used. Additionally, low grid voltage (check the grid voltage) or an improper V/F curve (set V/F curve and torque increase correctly) could be the cause.

What to do if my Megmeet MV600 DC Drives shows deceleration over-voltage?
- N
  nelsonseanAug 29, 2025
  If your Megmeet DC Drives shows deceleration over-voltage, it could be because the deceleration time is too short compared with regeneration energy, so lengthen the deceleration time. Another possible cause is potential energy load or large load inertial torque, so select appropriate dynamic braking components.

  Ian MayAug 27, 2025
  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).

  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).

  Lacey JacksonAug 26, 2025
  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).

  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).
