What to do if my Nidec NE300-4T0370G/0450P show motor overload?
- T
  Tanya BradfordAug 22, 2025
  If your Nidec DC Drives indicate a motor overload, several factors could be responsible. First, check the input power source for any abnormalities. Ensure the motor's rated current is correctly configured in the settings. If the V/F curve isn't suitable, adjust it along with the torque boosting performance. For motors consistently operating with heavy loads at low speeds, consider using a specialized electric motor. Also, verify that neither the motor nor the load is blocked or experiencing sudden, large load changes. Finally, if the motor power is insufficient, use a motor and drive with appropriate power ratings.

What causes over current in Nidec NE300-4T0370G/0450P DC Drives during acceleration and how to fix it?
- M
  Michael AndersonAug 23, 2025
  Overcurrent during acceleration in Nidec DC Drives can stem from a few reasons. If the acceleration time is too short, increase it. Also, check the input power source for low voltage. Finally, if the drive power rating is too small, choose a drive with higher capacity.

What causes over current at constant-speed in Nidec DC Drives?
- B
  Barry BoyleAug 26, 2025
  If you're experiencing overcurrent at a constant speed with your Nidec DC Drives, several factors could be the cause. Check the load for any abnormal mutations. Also, verify the input power source isn't experiencing low voltage. Ensure your drive has sufficient power capacity. Finally, if you're using closed-loop vector control, inspect the encoder and its wiring for any sudden disconnections.

What to do if Nidec NE300-4T0370G/0450P show drive overload?
- K
  Keith HubbardAug 27, 2025
  If your Nidec DC Drives are showing a drive overload, first check the input power source for low voltage. If the load is too heavy, select a drive with a bigger capacity. If the acceleration is too fast, increase the acceleration time. Also, avoid restarting the motor while it's still turning.

What causes over current in Nidec DC Drives during deceleration?
- J
  James CowanAug 27, 2025
  Overcurrent during deceleration in Nidec DC Drives can occur due to several reasons. If the deceleration time is too short, increase it. If there is a large load inertia, add suitable brake devices. Finally, if the drive power rating is too small, choose a higher capacity drive.

What to do if my Nidec NE300-4T0370G/0450P DC Drives show over voltage in deceleration?
- S
  Sherry WillisAug 29, 2025
  If your Nidec DC Drives are showing an overvoltage during deceleration, the deceleration time may be too short, so increase it. Also, if the load inertia is large, add suitable brake devices.

How to fix heat-sink over heat in Nidec NE300-4T0370G/0450P?
- A
  amanda86Aug 30, 2025
  To resolve heat-sink overheating in Nidec DC Drives, first lower the ambient temperature. If the fan is damaged, replace it. Also, ensure the fan air duct is clear of any blockages.

What to do if my Nidec DC Drives show over Voltage in Acceleration?
- B
  bmckinneySep 1, 2025
  If your Nidec DC Drives display an overvoltage during acceleration, it could be due to a too short acceleration time, so increase it. Another possible cause is an abnormal power supply, so check the input power source.

What to do if Nidec DC Drives show fast current limit fault?
- D
  Dawn GreenSep 3, 2025
  If your Nidec DC Drives are showing a fast current limit fault, it could be due to a load that is too large or a motor blocked to stall, so decrease the load and check the motor and mechanical part status. If the drive power rating is too small, choose a higher power drive. If the drive output circuit loop is grounded or short-circuited, remove the external fault.
