ECT60
Servo Mode 1:
When ECT60 works in servo mode 1, the motor parameters themselves do not participate in
motor control, and the user does not need to make special settings. The user can judge
whether the motor connection is normal by checking the self-identifying resistance and
inductance of the object.
Servo Mode 2:
When ECT60 driver works in servo mode 2, the closed-loop stepper motor is in FOC control
mode. Due to the special structure of the stepper motor, a weak magnetic control is required for
