The electronics for the KBPC is state-of-the-art and includes short circuit and transient
protection which provides the ultimate in reliability. Electronic overload protection prevents
motor burnout and demagnetization of PM motors. The control can be operated in either the
Speed or Torque mode via jumper selection.
Standard features include electronic start/stop and an LED indicator array for Power On, Stop
and Overload.
Although the KBPC is factory set for most applications, a variety of trimpots allow adjustment
of the following parameters: Minimum and Maximum Speed, Acceleration, Deceleration,
Current Limit, IR Comp, and Timed Current Limit. Optional features offered are: Run-Stop-Jog,
and Input Signal Isolation.

Notes:
(1)
Maximum recommended output voltage is 180 VDC at 230 VAC. Exceeding this output
voltage will cause a reduction in load regulation performance.
(2)
For shunt wound motor with lower field voltage, use F1 and L1 connection.
(3)
Consult motor manufacturers for constant torque speed range of motor. (Typical speed
range for most 3 HP motor is 20:1)
