  • 12-24Vdc, 4x8A continuous, 4x10A 25% duty
  • Synchronized parallel driving
  • Operates with pulse feedback from motors
  • Homing cycle & end of travel limits set by pulse counting
  • Programmable with wide range of motor control functions

Product description

EM-337 is a parallel synchro controller for up to 4 DC-motors. The controller has four H-bridge power stages. The driver works

with actuators that can offer pulse feedback signal. The control is done with FW / BW commands. The synchronization control will keep all motors in the same speed and position. If synchronous error exceedsthe set difference limit, all motors will be stopped. Device includes adjustable acceleration and deceleration ramps, which produce the smooth starts, stops and direction changes.Load compensation also enables good operation with asymmetric loads. Adjustable current limits can be set to protect motor and mechanics against overcurrent (over sized forces).
