The ER-340, ER-680 and ER-1220 series are series of speed controllers for shunt wound or permanent magnet motors, utilising speed feedback from the armature voltage, or from a shaft mounted tachogenerator.

ER-340/ER-680/ER-1220
  • Non-isolated component units
  • Incorporates an accurate current control loop to protect the drive and motor
ER-340i/ER-680i/ER-1220i
  • Isolated 1 quadrant speed controllers for shunt wound or permanent magnet motors
  • Incorporate a fully controlled thyristor bridge with a current loop to protect the drive and motor
  • Used in speed or current control modes
  • The drives can motor forward and will regenerate for reverse rotation by an external force
