Product Description

The Indramat RAC 3.5-200-460-A00-W1-220 is a RAC 3 series spindle drive controller. Current rating of the controller is 200 Amps. Control circuit on the controller requires 220 Volts AC input and consumes 200 VA power. Power section of the controller requires three-phase 380 to 460 Volts AC input at 50 to 60 Hertz. Allowed tolerance for the power input is 10%. Performance specifications for the RAC 3.5-200-460-A00-W1-220 include 92 Amps continuous controller current, 35 Amps continuous controller output, and 30 Amps continuous controller output at 8 kilohertz power section frequency. The rated peak controller output with reference to motor shaft is 55 kilowatts and the continuous controller output with reference to motor shaft is 27 kilowatts. Peak regeneration capacity of the controller is 55 kilowatts. These specifications are valid for 5 to 45 degrees Celsius ambient temperature and 1000 meters or less of altitude.

Additional bleeder, additional interface and additional encoder inputs are not available on the RAC 3.5-200-460-A00-W1-220. The controller supports ±10 Volts analog speed set point for connection to convectional CNC controls. A built in fan on the controller helps to force air over the hot parts and therefore aids in maintenance of ambient temperature within the thresholds recommended by Rexroth Indramat. To ensure smooth airflow a minimum clearance of 160 millimeters is required above and below the vertically mounted controller. Operation of the RAC 3.5-200-460-A00-W1-220 outside the recommended ambient conditions for temperature and altitude leads to output derating of the controller. For example if the ambient temperature reaches 55 degrees Celsius the output falls to 80% of rated values. Installation and maintenance of the RAC 3.5-200-460-A00-W1-220 should be carried out by trained personnel only. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
