Error codes

 

 

 

 

CPF11 to CPF14 and CPF16 to CPF19

Fault name : Control Circuit Error.

Cause1 : There is a self-diagnostic error in the control circuit.

Possible solution : Cycle power to the drive

                           If the problem continues, replace the control board or the entire drive. Contact a DMEB Service technician for help.

Cause2 : Connector on the operator is damaged.

Possible solution : Send your drive to DMEB Service for repair

 

OV

Fault name : Overvoltage

Voltage in the DC bus has exceeded the overvoltage detection level.

• For 200 V class: approximately 410 V

• For 400 V class: approximately 820 V (740 V when E1-01 is less than 400)

Cause 1 : Deceleration time is too short and regenerative energy flows from the motor into the drive.

Possible solution:

• Increase the deceleration time (C1-02, C1-04).
• Install a braking resistor or a dynamic braking resistor unit.
• Set L3-04 to 1 to enable stall prevention during deceleration.

Cause 2 : Stall prevention is enabled as the default setting.

Excessive braking load. The braking torque was too high, causing regenerative energy to charge the DC bus.

Possible solution : Reduce the braking torque, use a braking option, or lengthen decel time.

Cause 3 : Surge voltage entering from the drive input power.

Possible solution : Install a DC link choke.

Note: Voltage surge can result from thyristor convertor and phase advancing capacitor using same drive

main input power supply.

Cause 4 : Ground fault in the output circuit causing the DC bus capacitor to overcharge.

Possible solution :

• Check the motor wiring for ground faults.
• Correct grounding shorts and turn the power back on.

Cause 5 : Excessive regeneration when overshoot occurs after acceleration.

Solution : Lengthen the S-curve at acceleration end.

Cause 6 : Drive input power voltage is too high.

Possible solution :

• Check the voltage.
• Lower drive input power voltage within the limits listed in the specifications.

Cause 7 : The dynamic braking transistor is damaged. Inspect the drive at DMEB.

Cause 8 : The braking transistor is wired incorrectly.

Possible solution :

• Check braking transistor wiring for errors.
• Properly rewire the braking resistor device.

Cause 9: Drive fails to operate properly due to noise interference.

Possible solution :

• Review the list of possible solutions provided for controlling noise.
• Review the section on handling noise interference and check the control circuit lines, main circuit lines and ground wiring.

Cause 10 : Motor hunting occurs.

Possible solution :

• Adjust the parameters that control hunting.
• Set the hunting prevention gain (n1-02).

Cause 11 : Hardware problem

If the problem continues, replace the control board or the entire drive. Contact a DMEB Service technician for help.

 

LF

Fault name : Output Phase Loss

• Phase loss on the output side of the drive.

• Setting L8-07 to 1 or 2 enables Phase Loss Detection.

Cause1 : The output cable is disconnected

Possible solution : Check for wiring errors and properly connect the output cable.

                           Connect the wiring.

Cause2 : The motor winding is damaged

Possible solution : Check the resistance between motor lines

                           Replace the motor if the winding is damaged.

Cause3 : The output terminal is loose

Possible solution :     Apply the tightening torque specified in the manual to fasten the terminals. Refer to Main Circuit Wire Gauges and Tightening Torques on page 129 for details.

 Cause4 : The rated current of the motor being use is less than 5% of the drive rated current.

Possible solution : Check the drive selection and motor capacities.

Cause5 : An output transistor is damaged.

Possible solution : If the problem continues, replace the control board or the entire drive. Contact DMEB Service for more informations.

Cause6 : A sigle-phase motor is being used.

Possible solution : the drive cannot operate a single phase motor

 

rr

Fault name : Dynamic Braking Transistor

                   The built-in dynamic braking transistor failed.

Cause1 : The braking transistor is damaged.

Possible solution : Cycle power to the drive and check for reoccurence of the fault.

                           Replace either the control board or the entire drive. For instructions on replacing the control board, contact us.

Cause 2 : The control circuit is damaged.

Possible solution : Cycle power to the drive and check for reoccurence of the fault.

                           Replace either the control board or the entire drive. For instructions on replacing the control board, contact us.
