* Performance is for SCR rated PM motors only. Lower performance can be expected

with other motor types. Factory setting is for 3% load regulation.To obtain super ior
regulation, see instruction manual. Other factory trimpot settings are as follows:
CL-150% FL, ACCEL-3 secs., MIN-(0)-speed, MAX-full speed and IR-3 volts.

* CE Compliance Requires CE Approved RFI Filter

DESCRIPTION

The KBCC™ 5-Hp chassis control utilizes the
KBMM™ modular control to provide a reliable variable
speed SCR drive for PM and Shunt DC motors. The
KBCC is a full-featured control offering adjustable linear
acceleration and deceleration functions. In addition, the
control contains Enable (close to run) and Inhibit™ (close
to stop) circuitry. An exclusive feature found only in KB
drives is Auto Inhibit

®

. It provides a smooth, safe start

during rapid switching of the AC line.

The KBCC-255 is factory wired for armature feedback
which, for most applications, provides e xcellent perf ormance.
For superior performance, the control can easily be
converted to DC tachometer feedback.Provision is made
for both 7V and 50V per 1000 RPM tachs. Reliability is
enhanced by incorporating a separate 42.5 AMP DC
power bridge and both armature and control circuit fusing.

The KBCC is built on a rugged aluminum heatsink,
which is compact in size and easy to install. The control
is supplied with a remote 5K ohm potentiometer.
However, it can also be operated in a voltage following
mode by supplying 0 - 9VDC

isolated

analog voltage to
terminals P2 (+) and F-. Individual adjustment trimpots
are provided for minimum speed (MIN), maximum speed
