Ramps Group
Stop Deceleration
The value you enter here defines the deceleration rate which is used when the Stop destination is activated. The default is 100
RPM/second.
The Stop destination is found in the Ramps Group in the Assignments view.
Feedhold Decel/Accel
When the Feedhold destination is activated, the motor will decelerate to a stop in the time specified by the
FeedholdDecelTime parameter. When feedhold is cleared, the motor will accelerate back to speed in the same specified
period of time.
Feedhold is a means to halt the motor within a velocity profile and then return to the profile later at the exact same place in
the profile. Feedhold does not ramp and does not decelerate in terms of velocity. Instead, it stops by decelerating time. For
example, if the motor is running at 50 revs/second and feedhold is activated with 2 seconds specified in the
FeedholdDecelTime parameter, then the motor will actually slow and stop in 2 seconds as measured time (on a time/velocity
profile) goes from 100% to 0%.
Travel Limit Decel
The value entered here is the deceleration ramp that is used when a software or hardware travel limit is hit.
Torque View
The Torque View allows you to edit torque level and limit parameters as well as view real-time torque values when online.
By selecting Torque in the Hierarchy Tree, the Torque View will appear on the right (see Figure 47). The right part of the
window is divided into groups. An explanation of the groups and their functions is provided below.

Torque Level
This parameter sets the activation point for the Torque Level Active source. If set to 100%, the Torque Level Active source
will activate any time the Torque Command reaches or exceeds 100% continuous. This parameter is specified in Torque User
Units.
