Notes
This parameter must be set independently for each axis.
Function
Enter the peak torque (as a percentage of the servo’s rated continuous
current) to be allowed for attaining and maintaining position in the
negative travel direction.
Since motor torque is proportional to motor current, the following equation
can be used to determine a value to be entered here:
Maximum desired motor current
------------------------------- x 100%
Motor’s maximum rated current
Important: This parameter is only used if the velocity loop is closed in by
the CNC software.
