DC drive chassis. Rated at output voltage 0.17 to 1.0A DC; 1.7 to 10 ADC. The KBMG are ultracompact, full-wave regenerative drives capable of operating DC PM or Shunt motors in a bidirectional 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 reversing and controlled braking. Because of its excellent controllability and response time, the KBMG can replace servos in many applications. The control is factory set for armature feedback, which provides up to 1% load regulation over a motor base speed of 50:1. Tachgenerator feedback is also provided for superior load regulation if required. A simple jumper setting converts the KBMG to a torque control. In this mode, motor torque rather than motor speed is controlled.
