3.1 Setting User Constants According to Machine Characteristics
57
If dynamic brake stop mode is selected, specify the operation to be performed when the
motor stops.
Setting Meaning
Cn-01
0
Releases dynamic brake after the motor stops.
bit 7
1
Does not release dynamic brake even after the motor stops.
3.1.3 Restricting Torque
1) The Servopack can provide the following torque control:
D Torque restriction 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
D Torque control Level 3: To always control output torque, not speed
Level 4: To alternately use speed control and 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.
