Unidrive SP Fault codes 2
dESt Multiple parameters writing to the same destination parameter
Set Pr xx.00 to 12001 and check all visible parameters in the menus for duplication.
EEF EEPROM data corrupted - Drive mode switches to open loop and serial communication via RS485 times out
This error can only be cleared by loading and saving default parameters.
EnC1 Drive encoder fault: Encoder power supply overload
Check encoder power supply wiring and the encoder current requirement.
Maximum current: 200mA @ 15V or 300mA @ 8V and 5V.
EnC2 Drive encoder fault: Wire break (Encoder terminals 1 & 2, 3 & 4, 5 & 6)
Check cable continuity.
Check that feedback signals are connected correctly.
Ensure that the encoder power supply is set correctly in Pr 3.36.
Replace the feedback device.
If wire break detection on the main drive encoder input is not required, disable the Enc2 trip by setting Pr 3.40 to 0.
EnC3 Drive encoder fault: Phase offset incorrect while running
Check for noise in the encoder signals.
Check the shielding of the encoder.
Verify the mechanical mounting of the encoder.
Repeat the offset measurement test.
EnC4 Drive encoder fault: Feedback device communication failure
Ensure the encoder power supply is correct.
Ensure the baud rate is correctly set.
Check encoder wiring.
Replace the feedback device.
EnC5 Drive encoder fault: Checksum or CRC error
Check for noise in the encoder signals.
Verify the shielding of the encoder cable.
For EnDat encoders, check the communication resolution and/or perform auto-configuration using Pr 3.41.
EnC6 Drive encoder fault: Encoder reported an error
Replace the feedback device.
For SSI encoders, check the wiring and encoder supply setting.
EnC7 Drive encoder fault: Initialization failed
Reset the drive.
Check that the correct encoder type is entered into Pr 3.38.
Check encoder wiring.
Ensure the encoder power supply is set correctly.
Perform auto-configuration using Pr 3.41.
Replace the feedback device.
EnC8 Drive encoder fault: Auto-configuration on power-up failed
Change the setting of Pr 3.41 to 0 and manually enter the drive encoder turns (Pr 3.33) and the lines per revolution (Pr 3.34).
Check the communication resolution.
EnC9 Drive encoder fault: Position feedback selected from a Solutions Module slot that does not have a speed/position feedback Solutions Module installed
Check the setting of Pr 3.26 (or Pr 21.21 if the second motor parameters have been enabled).
EnC10 Drive encoder fault: Servo mode phasing failure due to incorrect encoder phase angle (Pr 3.25 or Pr 21.20)
Check encoder wiring.
Perform an autotune to measure the encoder phase angle or manually enter the correct phase angle in Pr 3.25 (or Pr 21.20).
Spurious EnC10 trips may occur in very dynamic applications. You can disable this trip by setting the overspeed threshold in Pr 3.08 to a value greater than zero. However, setting an overly large threshold value may prevent encoder faults from being detected, so use caution.
EnC11 Drive encoder fault: Alignment error between the analog signals of a SINCOS encoder and the digital count from the sine and cosine waveforms
Check the encoder cable shielding.
Examine the sine and cosine signals for noise.
EnC12 Drive encoder fault: Hiperface encoder - Encoder type could not be identified during auto-configuration
Ensure the encoder type can be auto-configured.
Check encoder wiring.
Enter parameters manually.
EnC14 Drive encoder fault: EnDat encoder - The number of communication bits defining the encoder position within a turn is too large
Select a different type of encoder.
The encoder may be faulty.
