What to do if write parameter error occurs: read only on Delta Servo Drives?
- JJamie BaileyAug 27, 2025
If the parameter is read only, correct the PR command and parameter setting value.
What to do if write parameter error occurs: read only on Delta Servo Drives?
If the parameter is read only, correct the PR command and parameter setting value.
What to do if write parameter error occurs: exceeds the limit of normal range on Delta ASDA-A2 Servo Drives?
If the parameter setting value exceeds the limit of normal range, correct the PR command and parameter setting value.
What to do if data range error occurs when accessing CANopen PDO object on Delta ASDA-A2 Servo Drives?
If the data in the message has exceeded the data range of the specified object, NMT Maser send “Reset node“ command to its slave or reset the fault by sending the control word (0x6040) through CAN communication (the value of CANopen object 0x6040 should be reset).
What causes encoder initial magnetic field error in Delta Servo Drives?
If your Delta Servo Drives are showing an encoder initial magnetic field error, it means that the magnetic field of the encoder U, V, W signal is in error. If the error does not clear after each checking is done, please contact your distributor for assistance or contact with Delta.
How to resolve write parameter error parameter lock in Delta ASDA-A2?
To resolve a write parameter error in Delta Servo Drives due to a parameter lock, where the parameter is write-protected when Servo On or the setting value is invalid, correct the Pr command and parameter setting value.
What causes a reverse limit switch error on Delta ASDA-A2?
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 Delta ASDA-A2 show Encoder temperature exceeds the protective range?
If your Delta Servo Drives are showing that the encoder temperature exceeds the protective range, above 105?, improve heat dissipation or reduce the loading of operation.
What does 'Forward Limit Error' mean on Delta ASDA-A2 Servo Drives?
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 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 excessive deviation in Delta ASDA-A2?
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.
