hello dear friends.
as you know in some of vfd and ac servo drives there is a feature with name of "auto tune".i am useing a teco ac servo drive and a servo motor to control speed of spindle.after connecting the motor to the coupling and set some parameters then active the parameter"auto tune" and then give setpoint and servo on the motor rotates without any problem but when i pull out the motor from the coupling(the motor without load)and apply power and setpoint to drive the drive display "over current alarm".
what is the problem?
should the "auto tunning " be done with load or without load
on the motor?
best regards.
