Product Description

The RAC 2.2-250-380-A0S-W1 is a main spindle controller. Due to its accurate control, high reliability, and high service life, the RAC 2.2-250-380-A0S-W1 has earned a worldwide reputation of being one of the best industrial spindle controllers. The spindle controller is designed by Rexroth Indramat; it functions effectively with servo motors that require a high current control, such as INDRAMAT 2AD asynchronous main spindle motors and 1MB frameless spindle motors.

The spindle drive delivers the best results when it is applied to numerically controlled industrial machines. The software components of the RAC 2.2-250-380-A0S-W1 spindle drive is designed to be very flexible; this flexibility allows the installation and servicing of the motor to be quite uncomplicated. The servo drive has an internal positioning loop; it uses a closed-loop control system to independently position and correct the spindle motor according to the instructions programmed in its software module.

The RAC 2.2-250-380-A0S-W1 spindle controller is designed with a sophisticated and efficient temperature control system. It has a built-in fan and a heatsink; the sink absorbs the excess heat produced but the controller while the fan/air blower blows either internal or external air over the heat sink, which transfers the air to the air via natural convention. In special cases, the spindle drive controller can be fitted with a cooling hose to make the heat dissipation more efficient.

The RAC 2.2-250-380-A0S-W1 spindle drive controller uses a control voltage of either 3 x AC 400Volts or 3 x AC 460 Volts. The controller's continuous power output is 65 kilowatts, while its peak power output is 78 kilowatts. Unlike all other spindle drive controllers, the RAC 2.2-250-380-A0S-W1 is ambient temperature tolerant as it can work optimally in ambient temperatures as high as 55 degrees Celsius. The controller weighs 121 kilograms. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
