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.
Description
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
