Model 340XRi / 680XRi / 1220XRi DC drive product manual HG102909 iss 9
1
This drive is an isolated 4 Quadrant speed controller for shunt wound or permanent magnet motors. It utilises
speed feedback from the armature voltage (Avf), or from a shaft mounted tachogenerator. It incorporates an
accurate current control loop to protect the drive and motor, and can be used in speed or current control
modes. The drive can operate in forward or reverse, motoring or regenerative braking.
Please obtain expert help if you are not qualified to install this equipment. Make safety a priority.
This
component is hazardous.
