- N
  Nathan KrauseAug 20, 2025
  If your Gefran DC Drives show a 'Drive I2t ovrld' error, it indicates an excessive drive overload. Wait until the 'Drive I2t accum' accumulator is zeroed before resetting the alarm and re-enabling the drive.

Why is there an undervoltage error on my gefran TPD32-EV-...-4B?
- K
  Kimberly VelezAug 25, 2025
  If your Gefran DC Drives unit reports an undervoltage, it could be due to several reasons: * The 'Undervolt thr' parameter is set incorrectly. * The incoming voltage to the terminals U/V/W is too low. * Poor cable connections. To resolve this, set the parameter correctly and acknowledge the failure via RESET, check the connections, and ensure the correct AC input voltage.

What to do if gefran TPD32-EV-...-4B DC Drives shows a failure supply?
- C
  Collin DavisAug 27, 2025
  If you are experiencing a 'Failure supply' with your Gefran DC Drives, where the voltages are below the permitted value, pull out the plug-in terminal strips of the regulator card and enter the Reset command. If no other failures are reported, check your wiring for a short-circuit, in some cases with the cable shielding. If this has not rectified the fault, remove the terminal strips of the I/O option card (if present) and try RESET once more.

How to fix overspeed in gefran TPD32-EV-...-4B DC Drives?
- V
  Veronica NashAug 28, 2025
  If your Gefran DC Drives report an overspeed error, it means the motor speed in the feedback circuit is excessive. Check that the 'Speed fbk sel' parameter is consistent with the feedback used (Encoder 1, Encoder 2, Tacho, Armature). Also, check the wiring if an encoder or tacho generator feedback circuit is used.

What causes delta frequency error in gefran TPD32-EV-...-4B DC Drives?
- N
  Nicholas ThorntonAug 30, 2025
  If your Gefran DC Drives display a 'Delta frequency' error, it means there's an excessive difference between the frequency of the three-phase power supply input and the measured value. Ensure the frequency of the three-phase power supply remains constant or within the threshold limit during operation.

Why are my gefran TPD32-EV-...-4B overheating?
- E
  Elizabeth Davis PhDSep 1, 2025
  If your Gefran DC Drives unit is overheating, it could be due to: * High heatsink temperature. * High ambient temperature. * Failure of the device fan (for devices > 88 A (American), 110 A (Standard)). * Dirty heatsink.

What causes overtemp motor in gefran TPD32-EV-...-4B?
- S
  Shari AvilaSep 2, 2025
  If your Gefran DC Drives show 'Overtemp Motor', it indicates the motor is over temperature, signaled by the thermistor to terminals 78/79. This can happen if the motor lacks a thermistor with no jumper between terminals 78 and 79, or if the cable between the thermistor connection and terminals 78 and 79 is interrupted. Also, overheating of motor can be caused by an extreme load cycle, high ambient temperature, a failed external fan, or too large a load at low speeds.

What does Enable seq err mean on gefran TPD32-EV-...-4B?
- S
  sburnettSep 5, 2025
  If your Gefran DC Drives display an 'Enable seq err' message, it means the drive is powered up or Reset with the Enable input connected to 24 V and the Drive is configured to run from the terminals. Refer to CONFIGURATION/Main commands.

How to troubleshoot bus loss on gefran TPD32-EV-...-4B?
- A
  Amy EdwardsSep 7, 2025
  If your Gefran DC Drives experience a bus loss, possibly due to a failure in the Bus connection (only with interface Bus option card), check the Bus connection. It could also be due to EMC compatibility problems. Try a RESET. If you are still unsuccessful: probable internal fault. Contact your sales office.
