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

ER-340XRi/ER-680XRi/ER-1220XRi

• Isolated 4 quadrant speed controllers for shunt wound or permanent magnet motors
• Incorporate an accurate current control loop to protect the drive and motor
• Used in speed or current control modes
• Operate in forward or reverse, motoring or regenerative braking
