Product Description

One of the main spindle drive controllers offered by Bosch Rexroth is RAC 3.5-150-460-A0I-W1-220  drive controller. It has an internal position control loop along with a provided broad space range. It has a 150A current type and a supply of voltage for the power electronics rated at 3 x AC 380 and 460V; It additionally operates at a frequency of 50/60Hz. It is suitable to be used as main spindle unit in numerically controlled machine tools. The controller resolves the rotor position with a maximum resolution of 1/4 000 000th of a revolution. It has a speed set point of +/- 10 Volts along with an emergency-stop circuit integrated inside it. The drive controller is equipped with an additional, optional interface which comes in the form of incremental encoder output for position control with C-axis operation of screwing, tapping.

The ideal temperature of the operation of this machine is ranged between +5 to +45 degrees Celsius and should not exceed 55 degrees Celsius. The maximum altitude that this unit can be installed at is of 1,000 meters over the sea level. This unit comes with a built in fan for cooling and it can be operated in humidity-endangered areas. The maximum ideal humidity is ranged at F according to DIN 40 040. The controller has protection against the penetration of objects in the radius that is greater than 50mm.

This unit additionally also has a supply voltage rate for control electronics of AC 220V/50…..60Hz. The drive controller emits heat during its operation. The main spindle controller can be shipped to any area in the world with a warranty period of one year.
