Alarm Code Err-1 of GSK AC Servo Drivers
Err-1 of GSK AC Servo Driver
Meaning:
Motor velocity exceeds t he setting value
(Refer to the PA54 top velocity limit)
Possible Cause 1:
Encoder feedback signal abnormality
Solution:
Inspect t he motor encoder or its signal connection or PA1 setting error
Possible cause 2:
In the velocity mode, acceleration/deceleration time constant setting is excessive small, so that the velocity overshoot value i s excessive big.
Solution:
Enlarge the acceleration time PA57 and the deceleration time PA58
Possible cause 3:
PA54 (top velocity limit) setting value excessive small.
Solution:
Correctly set the PA54 value based upon the motor’s nameplate.
Possible Cause 4:
Excessive big position command electric gear ratio
Solution:
Correctly set the electric gear ratio
Above also can apply to other GSK AC Servo Drive models
