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.
