6.9 Motor stopping methods for servo off and alarm
Motor stopping methods for servo off and alarm are listed in table 6.9.1.
Table6.9.1
Motor Stopping Method Description
Dynamic brake
After servo off, the circuit of motor is short-circuited to create
reluctance to stop the motor.
Free run The motor naturally stops due to friction.
Zero clamp Set velocity command to 0 to stop the motor.
Motor decelerates to a
stop.
Use emergency stop torque to let the motor decelerate to a
stop.
Motor states after stop are listed in table 6.9.2.
Table6.9.2
Motor State After Stop Description
Dynamic brake Use reluctance force to let the motor remain at stop.
Free run
The servo drive stops controlling the motor. If there is external
force (gravity), the load may move.
Zero clamp
The servo drive switches to internal position mode. The motor
remains at current position.
6.9.1 Motor stopping method when servo off
The motor stopping method when servo off is set by Pt001 = t.X (Stopping method for servo off and
Gr.A alarm).
Servo off to stop the motor can only be used for emergency.
During operation, when main circuit power supply or control circuit power supply is
OFF, the motor stopping method is to use dynamic brake to stop the motor. This
setting cannot be modified by parameter.
To reduce the movement caused by inertia, the default motor stopping method
when alarm occurs is zero clamp. But in different mechanisms, stopping the motor
by dynamic brake could be more suitable.
