Kbrg-22D full wave 4 quadrant speed and torque control
The KBRGâ„¢ is a full-wave regenerative drive capable
mode. Its 4-quadrant operation provides 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 controllability and response time,
the KBRGâ„¢ can replace servos in many applications. The
up to 1% load regulation over a motor base speed of 50:1.
regulation is required. By resetting mode jumper J7 to the
“TRQ†position, the KBRG™ can be changed from a speed
The drive contains a variety of “selectable†jumpers and
adjustment trimpots to allow for custom tailoring for exact
requirements. For example: jumper J6, when placed in the
“TCL†position, provides adjustable timed current limit from 1
to 15 seconds. This feature will protect the motor and control
by shutting the drive down after the preset time has elapsed.
The KBRGâ„¢ can be operated with either a two (2) or
three (3) wire start/stop circuit, or can be started from the
AC line. A set of dedicated relay contacts are provided
which are activated via the start/stop circuit. They can be
used to turn on or off corresponding equipment or to sound
Another important feature is the array of the LED’s,
which indicate the mode of operation the drive is in, and
also serve as a diagnostic tool. In addition, KB’s exclusive
? circuit provides safe, smooth starting during
rapid cycling of the AC line. The Overspeed Protect Circuit
prevents failure of the power bridge in extreme overhauling
Reliability of the KBRGâ„¢ is further enhanced with the
use of a high speed current limit circuit along with armature,
AC line and control circuit fusing and MOV transient
protection. A 5K remote potentiometer and full operating
