FIG. 3 – MOTOR SPEED vs POTENTIOMETER ROTATION – [SPEED MODE]
FIG. 4 – PRESET MOTOR SPEED vs MOTOR LOAD – [SPEED MODE]
When Jumper J1 is placed in the "TRQ" position, the drive will control motor torque as a
linear function of main potentiometer rotation. If the motor load exceeds the torque
setting, the motor will stall, the Overload LED will light, and the drive will apply a constant
preset torque based on the potentiometer setting. The Overload LED will light when the
load torque approaches the current limit set point. The torque limits are set via jumper
J4 and the CL trimpot. (Note: When operating in the Torque Mode, Jumper J5 must be
in the "NTCL" position or drive will shut down when CL Timer times out.)
