Product Description

The RAC 2.3-250-380-A0I-W1 drive controller is a main spindle drive controller manufactured by Bosch Rexroth. It has a typical current of 250 amps, a rated connection voltage of 3x400 Volts AC, rated frequency ratings of 50-60 hertz, and a mounted blower. It also comes with two interfaces namely analog speed selecting interface and incremental encoder output interface. However, it doesn’t have an additional bleeder. The 2AD main spindle motors are compatible to use with the RAC 2.3-250-380-A0I-W1 drive controller. It offers safe motion functions to ensure the durability of the motor. It provides an internal position control loop which offers excellent spindle motor performance with increased accuracy. It also provides a wide speed range while keeping the heating and motor noise to a minimum.  

The RAC 2.3-250-380-A0I-W1 drive controller is capable of evaluating the spindle position through the motor feedback. The high-resolution main spindle position encoder provides the required feedback to control the speed and the position of the spindle to ensure the accuracy of the movements. The RAC 2.3-250-380-A0I-W1 controller device selects the spindle position signal with a precision of up to 1/4000000 of a rotation. It offers a wide range of functions including c-axis function, power and torque limits, drive utilization output, temperature pre-warning, maximum spindle speed, spindle monitor, and switchable parameter records. The RAC 2.3-250-380-A0I-W1 drive controller has an analog interface for transmitting the speed command values. The bottom of the module has a connector to interface with the AS programming module. The parameter values, such as motor optimizing parameter values can be inserted on-site during commissioning. However, these drive features are stored inside the programming module and can be reused with other hardware. This module offers a wide range of functions for numerous applications. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
