What to do if TOPTEK DC Drives show Over-current (oC) {01}?

  If a TOPTEK DC Drive shows an Over-current (oC) {01} error, first check the wiring between the drive and motor for short circuits. If there are no short circuits, increase the Acceleration time (Pr1-11, Pr1-12). Also, verify that the motor isn't excessively loaded. If the issue persists, consider replacing the drive with a higher power model. After addressing the potential causes, wait 60 seconds and then perform a RESET to reactivate the operation.

What to do if TOPTEK TOPVERT E1 DC Drives show Over-voltage on DC-Bus (oU) {02}?
- K
  Kevin SmithJul 30, 2025
  If a TOPTEK DC Drive displays an Over-voltage on DC-Bus (oU) {02} error, verify that the input voltage is within the drive's rated range. Also, check for any voltage transients. If the over-voltage is due to regenerative voltage, increase the Deceleration time or add an optional brake unit and brake resistor.

What to do if TOPTEK TOPVERT E1 DC Drives show Over-voltage on DC-Bus during deceleration (oUd) {37}?
- L

  If a TOPTEK DC Drive shows an Over-voltage on DC-Bus during deceleration (oUd) {37} error, check that the input voltage is within the rated range for the drive. If the DC Bus over-voltage is due to regenerative voltage, increase the deceleration time or install a brake unit and brake resistor (optional). Also, confirm that the braking power required is within specified limits.

  If a TOPTEK DC Drive displays a Ground fault (GF) {03} error, check the wiring between the drive and motor for short circuits, especially to ground. Inspect the IGBT power module for damage. Also, check the output line for poor insulation. After correcting any issues, wait 60 seconds and then execute a RESET action to reactivate the operation.

What to do if my TOPTEK TOPVERT E1 DC Drives shows an over-current (oC) error?
- J
  James BranchAug 11, 2025
  If your TOPTEK DC Drive displays an over-current (oC) error, first, inspect the wiring between the drive and motor for any short circuits. If the wiring is correct, try increasing the Acceleration time (Pr1-11, Pr1-12). Also, verify that the motor isn't experiencing excessive load. If the problem persists, consider upgrading to a higher power drive model. As a temporary measure, you can wait 60 seconds and then perform a RESET to attempt to resume operation.

What to do if TOPTEK TOPVERT E1 displays an over-voltage (oU) on DC-Bus?
- R
  Ryan LeeAug 15, 2025
  If your TOPTEK DC Drive shows an over-voltage (oU) error on the DC-Bus, ensure that the input voltage is within the drive's rated range. Also, check for any voltage transients that might be occurring. If the over-voltage is due to regenerative voltage, you can increase the Deceleration time or install a brake unit and brake resistor (optional).

What to do if TOPTEK DC Drives shows over-voltage on DC-Bus during deceleration (oUd)?
- E
  Erin HerreraAug 20, 2025
  If your TOPTEK DC Drive is showing an over-voltage (oUd) on the DC-Bus during deceleration, first confirm that the input voltage remains within the specified range for the drive. If the issue persists, and is due to regenerative voltage, try increasing the deceleration time or consider adding a brake unit and brake resistor (optional). Also, check that the required braking power does not exceed the specified limits.
