To Calibrate the MIN Trimpot:
1. Adjust the MIN trimpot to the desired position
and set the Main Speed Potentiometer fully
counterclockwise.
2. Monitor the armature voltage and readjust the
MIN trimpot to the desired voltage.
C. Acceleration (ACC) – Sets the amount of time it
takes for the control voltage to reach full output.
The ACC trimpot is factory set to 1 second. To
increase the acceleration time, rotate the ACC trim-
pot clockwise. To decrease the acceleration time,
rotate the ACC trimpot counterclockwise. See
Figure 13.
D. Deceleration (DEC) – Sets the amount of time it
takes for the control voltage to reach zero. The
DEC trimpot is factory set to 1 second. To increase
he deceleration time, rotate the DEC trimpot clock-
wise. To decrease the deceleration time, rotate the
DEC trimpot counterclockwise. See Figure 14.
E. Current Limit (CL) – Sets the current limit (over-
load), which limits the maximum current to the
motor. The CL trimpot is factory set to 150% of the
nominal motor current established by the Plug-In
Horsepower Resistor®. See Table 3, on page 12.
To increase the current limit, rotate the CL trimpot
clockwise. To decrease the current limit, rotate the
CL trimpot counterclockwise. See Figure 15.
