CURRENT (TORQUE) LIMIT ADJUST (CL)
(Clockwise Increases Current)
There are two methods for adjusting CL.
METHOD 1:
1. Start the machine and run at desired speed, then apply
maximum load to the motor and turn CL trimpot fully
clockwise.
2. Turn CL trimpot counterclockwise until the CL . (yellow) LED
lights and the machine starts to slow down.
3. Turn the CL trimpot clockwise until the CL (yellow) LED just
turns off.
METHOD 2:
1. Turn off AC power.
2. Lock up the motor shaft, taking care not to cause damage.
3. Connect a DC ammeter in series with the motor armature.
4. Turn CL trimpot fully counterclockwise.
5. Turn external speed pot fully counterclockwise.
6. Turn on AC power and start control (CL (yellow) LED should
be on).
7. Turn speed pot clockwise to about 1/3 speed setting.
8. Adjust CL trimpot clockwise for desired motor current. (Do
not set for current greater than either the motor or control
nameplate rating).
9. Turn off AC power, disconnect ammeter, and unlock motor
shaft. CL may be adjusted from O-150% of control rating.
