Product Description

The Rexroth RAC 3.5-150-460-LP0-Z1-220 is a 150 Amps rated spindle drive controller. It belongs to RAC 3 product family from Rexroth Indramat. Programming of the controller is performed through the keypad located on the front of the controller. The configured parameters are stored with motor parameters on the programming module. This enables replacement of a faulty controller with a working controller while the same programming module - which contains the drive parameters - can be used. RAC 3 controllers are available with either analog, digital or SERCOS set-point interfaces. The RAC 3.5-150-460-LP0-Z1-220 comes with SERCOS interface for real-time communication with CNC controls. The controller also includes an additional encoder input for 2^nd motor feedback or for spindle feedback and an additional bleeder for braking with mains voltage failure.

Additional interface is not available on the controller. Input voltage rating of the RAC 3.5-150-460-LP0-Z1-220 is three-phase 380 to 480 Volts AC with 10% allowed tolerance. Control circuit on the controller is rated for 220 Volts AC input. Supported line frequency range for power input and for control circuit input is 50 to 60 Hertz. Power requirement of the control circuit is 200 VA. The RAC 3.5-150-460-LP0-Z1-220 is cooled by means of an integrated cooling fan. The continuous current rating of the RAC 3.5-150-460-LP0-Z1-220 is 92 Amps. The continuous controller output with reference to motor output shaft is 35 Amps. The peak controller output is 40 kilowatts. Approximate shipping weight of the RAC 3.5-150-460-LP0-Z1-220 is 49 kilograms. Housing of the controller is designed for vertical mounting and has IP 10 protection rating. For optimal performance the controller should be installed at altitudes of up to 1000 meters. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
