How to solve DSP firmware upgrade issue on Delta Servo Drives?
To solve a DSP firmware upgrade issue on Delta Servo Drives, set P2-08 to 30 first, and then 28 next, and restart the servo drive.
What is motor protection error on Delta ASD-A2-0421?
A motor protection error on Delta Servo Drives means that the setting value of parameter P1-57 is reached after a period of time set by parameter P1-58. Set P1-57 to 0. Correctly set P1-57 and P1-58.
What does pre-overload warning mean for Delta ASD-A2-0421 Servo Drives?
A pre-overload warning for Delta Servo Drives means that the drive is going to overload. Please refer to the correction actions of AL006. Increase the setting value of P1-56 or set P1-56 to 100 and above.
What does input power phase loss mean for Delta Servo Drives?
If your Delta Servo Drive is experiencing input power phase loss, it indicates that the control power supply is in error. If the fault persists even when the three-phase power is connected correctly, please contact your distributor or Delta for assistance.
What does it mean when my Delta Servo Drive has a memory error?
A memory error on your Delta Servo Drive can occur due to: * Parameter data error when writing into EE-PROM. If this is the case, correct the setting value of the parameter to clear the fault and restart the servo drive. * The setting value of a hidden parameter is in error. If this fault occurs when resetting the parameter settings, it indicates that the servo drive type is not set correctly. Correctly set the servo drive type again. * Data in EE-PROM is damaged. If this is the case, please contact your distributor or Delta for assistance.
What causes IGBT temperature error in Delta ASD-A2-0421?
An IGBT temperature error in Delta Servo Drives can occur if: * The drive has exceeded its rated load during continuous operation. If this is the case, increase motor capacity or reduce load. * There is a short-circuit at the drive output. If this is the case, ensure all wiring is correct.
What causes excessive deviation in Delta ASD-A2-0421 Servo Drives?
Excessive deviation in Delta Servo Drives can be caused by: * Maximum deviation parameter setting is too small. If this is the case, increase the parameter setting value of P2-35. * Gain value is too small. If this is the case, correctly adjust gain value. * Torque limit is too low. If this is the case, correctly adjust torque limit value. * There is an overload. If this is the case, reduce external applied load or re-estimate the motor capacity.
What causes undervoltage in Delta ASD-A2-0421 Servo Drives and how to fix it?
Undervoltage in Delta Servo Drives can be caused by: * The main circuit voltage being below its minimum specified value. If this is the case, reconfirm voltage wiring. * No input voltage at the main circuit. If this is the case, reconfirm the power switch. * Incorrect power input. If this is the case, use the correct power supply, a stabilizing power supply, or a series transformer.
What causes a reverse limit switch error on Delta ASD-A2-0421 Servo Drives?
A reverse limit switch error on Delta Servo Drives can be triggered by: * The reverse limit switch being activated. If this is the case, activate reverse limit switch. * An unstable servo system. If this is the case, modify parameter setting and re-estimate motor capacity.
What to do if there is an analog input voltage error on Delta Servo Drives?
If there is an analog input voltage error on Delta Servo Drives, it means that the analog input voltage is higher than the value of P1-83 over 50ms. Check all analog input voltages. Check if there is any question about the sources of analog speed commands.
