What to do if Nidec NE300-4T2000G/2200P-U DC Drives show EEPROM error?
If your Nidec DC Drives are showing an EEPROM error: 1. Recover factory defaults if function code parameter writing error. 2. Ask for service from supplier, if EEPROM damaged.
What causes over current in Nidec NE300-4T2000G/2200P-U during acceleration and how to fix it?
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?
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 DC Drives show drive overload?
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 NE300-4T2000G/2200P-U during deceleration?
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 Nidec DC Drives show keypad & control board communication interrupted?
If communication between the keypad and control board is interrupted on your Nidec DC Drives, check the connection cable between the keypad and control panel.
What to do if Nidec DC Drives show external terminal fault?
If your Nidec DC Drives are showing an external terminal fault, check the external input, as the fault likely originates from the external control circuit.
What to do if Nidec DC Drives show Parameter copy Error?
If your Nidec DC Drives are showing a Parameter copy Error: 1. Shorten the cable between Keypad and control board to reduce interference if too long connection cable between keypad and control board leads to interference in parameters transmission. 2. Before downloading, make sure the parameters match the drive, if the downloading parameters do not match the existed parameters in the drive.
What to do if Nidec NE300-4T2000G/2200P-U DC Drives show ground fault?
If your Nidec DC Drives are indicating a ground fault, it could be due to a short circuit in one of the output phases. Check whether the electric motor insulation is weakening. Also, check whether the wiring between the frequency converter and the electric motor is damaged.
What to do if Nidec NE300-4T2000G/2200P-U show fast current limit fault?
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.
