2 Torque Taper Kit for Non-Regenerative FlexPak Plus and MinPak Plus DC Drives
Installing and Adjusting the Torque Taper Kit
Refer to your drive instruction manual for help locating and identifying drive components.
To install the Torque Taper kit in your non-regenerative FlexPak Plus or MinPak Plus DC drive:
Step 1. Disconnect, lock out, and tag input power to the drive.
Step 2. Remove the drive cover and verify that no voltage is present at the drive’s AC input terminals, L1/181
and L2/182.
Step 3. Remove jumpers J7 and J8 on the Regulator module. See figure 2.
Step 4. Orient the Torque Taper module over the area marked TORQUE TAPER on the Regulator module,
just over the seven pins. Press down so that the pins pass through the guides on the Torque Taper
module. Use the mounting screw to secure it.
Step 5. On the Regulator module, adjust the Current Limit potentiometer counter-clockwise (CCW) to 100%,
or lower, depending on the application. It is shipped from the factory set at 150%. Dot No. 4 is
approximately 100%. Refer to figure 3.
Step 6. On the Torque Taper module, turn the CORE TORQUE potentiometer completely CCW. The core
torque setting provides a minimum winding torque, or mimimum strip tension, when the winding cycle
begins.
Step 7. On the Torque Taper module, turn the TORQUE TAP. ADJ. potentiometer completely CW. This
assures that excessive tension will not develop as the first coil or package is wound.
Important: The remaining steps assume that the complete drive system has been successfully started up
according to the instructions in the drive user manual. They provide a power-on test.
Note that an ammeter in the armature circuit is useful when adjusting both potentiometers on the
Torque Taper module. Abserving the ammeter, which shows current, and the growing coil diameter
gives visual confirmation whether the current (Torque) is increasing too fast or slow in relation to
the build-up.
Step 8. Thread the strip onto the winder and securely fasten it to the core. Remove all strip slack before the
drive is restarted.
Step 9. Set the Maximum Speed potentiometer for a safe maximum winder speed.
Step 10. Remove the lockout and tag. Apply power to the drive.
Step 11. Start the drive.
If the strip web breaks immediately, stop the drive. Reduce the Current Limit potentiometer (CCW
reduces current (torque).

ATTENTION: Do not install modification kits with power applied to the drive. Disconnect, lock
out, and tag all sources of incoming AC power to the drive before attempting such installation.
Verify that no voltage is present at the drive’s AC input terminals, L1/181 and L2/182. Failure to
observe this precaution could result in severe bodily injury or loss of life.
ATTENTION: The user is responsible for conforming with all applicable local, national, and
international codes. Failure to observe this precaution could result in damage to, or destruction
of, the equipment.
