Torque Taper Kit

for Non-Regenerative FlexPak Plus

and MinPak Plus DC Drives

Model Number 14C224

Instruction Manual D2-3386

Product Description

The Torque Taper kit allows fine adjustment of the slope and breakpoint of the drive’s speed-torque curve. It
should be used where simple, center-driven winders and similar applications require a reciprocal speed-torque
relationship to maintain constant tension as material builds up. In these cases, a higher current limit (higher
torque) setting is required for a decrease in motor speed due to a growing diameter. See figure 1.

The Torque Taper kit comprises a module (printed circuit board) and a mounting screw. No other equipment is
required. However, the Speed potentiometer and either the Torque potentiometer or the Current Limit
potentiometer on the drive’s Regulator module are used in conjunction with the two potentiometers on the
Torque Taper module.

ATTENTION: Only qualified electrical personnel familiar with the construction and operation of
this equipment and the hazards involved should install, adjust, operate, and/or service this
equipment. Read and understand this manual and other applicable manuals in their entirety
before proceeding. Failure to observe this precaution could result in severe bodily injury or loss
of life.
