How to resolve excessive deviation of position command on Delta Servo Drives?
- P
  psandovalAug 28, 2025
  Excessive deviation of position command in Delta Servo Drives can be addressed by: * Increasing the setting value of P2-35 if it is set too small. * Correctly adjusting the gain value if the setting is too small. * Correctly adjusting the torque limit value if the torque limit is too low. * Reducing the external load or re-evaluating the motor capacity if there is excessive external load. * Correctly setting up the E-gear ratio if it is improperly set.

What to do if Delta Servo Drives show abnormal pulse command?
- B
  Beverly SmithAug 28, 2025
  If your Delta Servo Drives are showing an abnormal pulse command, it could be because the pulse command frequency is higher than the rated input frequency. Correctly set the input pulse frequency.

What does 'Forward Limit Error' mean on Delta ECMA-C 0807?
- C
  Cindy GomezAug 31, 2025
  A forward limit error on Delta Servo Drives indicates: * The forward limit switch is activated: Enable the forward limit switch. * The servo system is unstable: Re-adjust the parameter or evaluate the motor capacity.

What causes abnormal EEPROM in Delta ECMA-C 0807?
- C
  Craig McphersonAug 31, 2025
  If your Delta Servo Drives are showing an abnormal EEPROM: * It is in error when DSP accesses EEPROM: The fault occurs when applying to the power. It means one of the parameters is over the reasonable range. Please re-power on after adjusting. The fault occurs in normal operation. It means it is in error when writing the parameter. The alarm can be cleared by DI.ARST. * Abnormal hidden parameter: Please set the correct type of the drive. * Data in ROM is damaged: Please send the drive back to the distributors or contact with Delta.

What causes Abnormal Signal Output in Delta ECMA-C 0807?
- R
  Rachel AndersenSep 1, 2025
  If your Delta Servo Drives are showing abnormal signal output: * The encoder is in error and cause the abnormal signal output: Conduct the corrective actions of AL.011, AL.024, AL.025, AL.026. * The output pulse exceeds the hardware allowable range: Correctly set parameter P1-76 and P1-46.
