What to do if my Delta ECMA-C 0807 Servo Drives show overload?
- J
  joseph60Aug 25, 2025
  If your Delta Servo Drives are showing overload, consider the following: * The drive is experiencing continuous excessive use beyond its rated loading: Increase the motor capacity or reduce the load. * The control system parameter settings are inappropriate: Adjust the gain value of the control circuit. * There is incorrect wiring of the motor and encoder: Ensure correct wiring. * The motor's encoder is defective: Send the drive back to the distributors or contact Delta.

Why is my Delta ECMA-C 0807 Servo Drives showing over voltage?
- T
  Timothy HerreraAug 26, 2025
  If your Delta Servo Drive displays an over voltage error, it could be due to: * The input voltage of the main circuit exceeding the rated allowable voltage: Apply the correct power supply or a serial voltage regulator. * Incorrect power input (wrong power system): Use the correct power supply or a serial adapter. * Damage to the servo drive hardware: Send the drive back to the distributors or contact Delta.

How to troubleshoot regeneration error in Delta ECMA-C 0807?
- R
  Rachel ShepardAug 26, 2025
  If you're encountering a regeneration error with your Delta Servo Drives, here's what to check: * The regenerative resistor is either unconnected or its resistance is too low: Reconnect the regenerative resistor or calculate the appropriate value. * Parameter P1-53 isn't set to zero when a regenerative resistor isn't being used: Set parameter P1-53 to zero when the resistor is not in use. * Incorrect parameter settings: Reset the settings correctly.

What causes under voltage in Delta Servo Drives and how to fix it?
- M
  Mr. Thomas EvansAug 27, 2025
  An under voltage error in Delta Servo Drives can stem from: * The main circuit's input voltage being lower than the rated allowable voltage: Re-confirm the voltage wiring. * No power supply to the main circuit: Check the power switch. * Incorrect power input (incorrect power system): Apply the correct power supply or serial adapter.

What causes overspeed in Delta Servo Drives?
- S
  Shawn TaylorAug 27, 2025
  Overspeed errors in Delta Servo Drives can occur due to: * Unreasonable command: Use a less steep command or apply a filter to smooth the command. * Inappropriate parameter setting: Correctly set parameter P2-34 (the condition of over-speed warning).

Why does my Delta Servo Drives display 'Motor Combination Error'?
- T
  Thomas WilliamsonAug 28, 2025
  A 'Motor Combination Error' on your Delta Servo Drives could indicate: * A damaged encoder: Change the motor. * A loose encoder: Install the motor again. * A motor combination error: Change the motor.

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.

How to fix IGBT Overheat in Delta ECMA-C 0807 Servo Drives?
- R
  Ronald GuerraAug 29, 2025
  If your Delta Servo Drives are showing IGBT Overheat, consider the following: * The drive is experiencing continuous excessive use beyond its rated loading: Increase the motor capacity or reduce the load. * The drive output is short-circuit: Ensure correct wiring.
