Product Description

The RAC 2.3-250-460-A0I-W1 is an advanced and sophisticated main spindle drive controller manufactured by Indramat. The drive controller is designed to control and monitor the speed and position of two main types of Indramat servo motors: The Indramat 2AD asynchronous main spindle motors and The 1MB frameless spindle motors with a continuous motor power output of 30 to 52 kilowatts. Servo motors controlled by the RAC 2.3-250-460-A0I-W1 spindle drive controller can be distinguished by their broad speed range, high stiffness, high accuracy, and broad power output. The unique characteristics of servo motors controlled by the RAC 2.3-250-460-A0I-W1 spindle drive make the spindle drive particularly effective in Numerically Controlled machines.

The RAC 2.3-250-460-A0I-W1 spindle drive controller is produced under ideal industrial conditions according to international standards. It is delivered with a special plugged-in AS programming module, which helps it adapt to a specific servo motor and implement the spindle controller's unique characteristics. The contains a heat sink and air blower, which it uses to regulate its internal temperature via Natural Convention. The drive controller does not contain an additional bleeder resistor.

Under normal operations, servo motors connected to the RAC 2.3-250-460-A0I-W1 spindle drive controller deliver a continuous power output of 65 kilowatts and a maximum power output of 78 kilowatts. In the case of an interruption of the electrical power going into the driven motor, the motor can still generate a continuous regeneration power of 48 kilowatts and maintains a peak regeneration power output of 78 kilowatts for about 3 seconds. The drive controller should not be operated at an ambient temperature greater than 55 degrees Celsius or installed at an elevation greater than 1000 meters above sea level. The drive controller weighs about 121 kilograms. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
