Product Description

The RAC 2.2-150-380-A0D-W1 drive controller manufactured by Bosch Rexroth has a 150A current rating and a 3 x 400VAC connections voltage rating. The drives using the main spindle drive controller can be operated as main spindle drives for machine tools that are controlled numerically. The internal position control loop of the product is closed using motor feedback or spindle feedback. The controller can be cooled during its functioning through air circulation either inside or outside the control cabinet in which it is mounted. The control panel of the device is integrated with a keypad.

The main spindle drive controller is capable of supplying an extra modular controller with a control voltage bus and a link circuit connection. The parameters for installation as well as application are input during the commissioning stage with the help of the keypad. The product features a +/-10V analog speed set-point that can be connected to standard CNC controls. The device renders a decreased performance if the rated ambient conditions are exceeded. The rated power and torque become lower when the installation altitude exceeds 1,000m. The RAC 2.2-150-380-A0D-W1 main spindle drive controller can be delivered internally through shipping agents like FedEx.

The device can be made to function in workshops located in dry-warm and cold-moderate climates. It has a protection class of IP 10 in adherence to EN 60529 or DIN VDE 0470 specifications. The unit comes with a mechanical fitting kit that contains the components such as gaskets and screws required for delivery. The external power and internal power dissipated by the product is dependent on the workload. The drive controller should always be installed such that condensation water does not fall on it. The main spindle drives make use of standard cables for their electrical connections. This drive controller is available with a warranty period of one year.
