Product Description

The RAC 2.3-250-380-API-Z1 is a main spindle drive controller produced by Indramat. The drives implementing this equipment are characterized by a wide range of speed controls and high stiffness. The maximum pressure and minimum air flow requirement of RAC 2 drives are 390 Pascals and 360 m³/h respectively. The power dissipation of this drive controller is dependent on the extent of load.

The RAC 2.3-250-380-LP0-W1 weighs 121 kg, and its mounting frame, M1-RAC4, weighs 2 kg. Its rated current is 400 Amps and a connection voltage rating of 380 Volts. It features an analogue (±10 V) speed set-point interface and an additional encoder input for motor for spindle. The drive controller does not have an additional bleeder. This RAC 2 drive controller is only usable at a temperature of 45 degrees without derating its specifications. To maintain the temperature of the RAC 2.3-250-380-LP0-W1, a cooling device (built-in fan) is utilized to withdraw internal heat from its control cabinet. The temperature limit of the cooling device should be set at 40 degrees at all times.

The output power of the RAC 2.3-250-380-LP0-W1 in relation to the output shaft of the motor is 65 kW. The peak power output of the controller is 78 kW, and its continuous regeneration power output is 43 kW. At a maximum time of 5 seconds, the peak regenerated power output of the RAC 2.3-250-380-LP0-W1 is 78 kW. The protection type for this equipment is IP 10, per DIN VDE 0470 (EN 60 529) standards. As a safety guideline, the maximum allowable overpressure and air flow values of the RAC 2.3-250-380-LP0-W1 should be kept in check at all times. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
