summed torque enters the torque selection block (refer to Torque Reference on
page
175 for more information).
Parameter 55 [Speed Comp] contains the rate of acceleration or deceleration
calculated in the inertia compensation block. This parameter is used in following
applications. Link parameter 23 [Speed Trim 3] to [Speed Comp] and set
parameter 24 [SpeedTrim3 Scale] to 0.002 to reduce position error in following
applications.

Jog A jog reference is usually used to run the motor at some preset, low speed. Two
separate jog speeds can be used as a speed reference - parameter 17 [ Jog Speed 1]
or parameter 18 [ Jog Speed 2]. A jog could be initiated by a Digital Input, by the
Logic Command word from a DPI Adapter such as a HIM, or by the Logic
Command word from DriveLogix. In turn, a valid jog command initiated from
one of those adapters will turn on either bit 18 in parameter 152 [Applied
LogicCmd] to select jog speed 1 or bit 23 in [Applied LogicCmd] to select jog
