3.1.3 Restricting Torque

1) The Servopack can provide the following torque control:
D Torque restriction
D Torque control
This section describes how to use levels 1 and 2 of the torque restriction function.

2) How to Set Level 1: Internal Torque Limit

The maximum torque is restricted to the values set in the following user constants.
Cn-08
Cn-09
Setting
0 Stops the motor by dynamic brake.
Causes the motor to coast to a stop.
1
The motor power is OFF and stops due to machine friction.
Setting
0 Releases dynamic brake after the motor stops.
1 Does not release dynamic brake even after the motor stops.
Level 1: To restrict the maximum output torque to
protect the machine or workpiece
Level 2: To restrict torque after the motor moves the
machine to a specified position
Level 3: To always control output torque, not speed
Level 4: To alternately use speed control and torque
