DESCRIPTION
The KBRC-240D is a Full-W
IP-65 washdown and watertight enclosure. It is designed to operate 90 and
180 Volt Permanent Magnet and Shunt Wound DC motors in a bidirectional
mode. It provides 4-quadrant operation, which allows forward and reverse
torque in both speed directions. This allows the control to maintain constant
speed with overhauling loads and provides rapid instant reversing and
controlled braking. Because of its excellent performance, the control can
replace servo drives in many applications.
The KBRC-240D has a Regeneration Overspeed Protection Circuit,
which prevents failure of the power bridge in extreme overhauling conditions. Motor overload protection (I x t) will shut down control if the motor is
overloaded for a predetermined amount of time. The exclusive Auto-Inhibit
circuit allows safe, smooth starting during rapid cycling of the AC line.
Due to its user-friendly design, the KBRC-240D is easy to install and
operate. Tailoring to specific applications is accomplished via selectable
jumpers and trimpot adjustments. However, for most applications, no
adjustments are necessary.
The KBRC-240D can be operated from a two or three wire start/stop
circuit or can be started from the AC line. A set of dedicated normally open
or normally closed relay contacts are provided, which are activated via the
start/stop circuit. They can be used to turn on or off equipment or to signal
a warning if the control is put into Stop Mode or times out in TCL.
Main features of the KBRC-240D include Speed or Torque control
modes. In Linear Torque mode (S/L), speed and torque vary linearly as a
function of main speed potentiometer rotation or input signal. In Non-Linear
Torque mode (NL), the torque is varied by the main speed potentiometer or
input signal, and remains constant throughout the motor’s entire speed
range. In addition, Regenerate-to-Stop (R
ing modes are also provided.
Standard front panel features of the KBRC-240D include diagnostic
LEDs (for Power On, Stop and Overload), a Start/Stop Switch and a Main
Speed Potentiometer. Other features include Barrier Terminal Blocks (facilitates wiring of the AC line, motor, tach-generator and run relay), adjustable
trimpots (OFFSET
TCL), selectable jumpers (AC line voltage, motor voltage or tach feed
and
back, motor current, analog input voltage, control mode, torque mode, cur
rent limit mode, regeneration mode, run relay and enable) and LEDs (Power
On, Overload, Forward Enable and Reverse Enable).
Optional accessories for the KBRC-240D include a Forward-StopReverse Switch, a Power On/Off Switch, a Signal Isolator and an
Auto/Manual Switch. Quick-connect terminals are provided for easy
installation of all accessories.
