RAC 4.1-300-460-AP0-W1

Product Description

The RAC 4.1-300-460-AP0-W1 offers control for frameless spindle motors and are especially suited for motors that are numerically controlled and have a broad range of speed. This drive can position the spindle autonomously.

The RAC 4.1-300-460-AP0-W1 can be connected to a three-phase supply network with a rating of 3 x AC 400V, 50Hz. In the case of power outage or during emergencies off, the drive implementing this drive controller can stop the main spindle by using d.c. current braking. This drive controller is well ventilated and receives cool air from within and without the cooling cabinet. Its speed set-point is delivered via an analogue set-point (+/- 10V). Although, RAC 4.1-300-460-AP0-W1 lacks the non-compulsory additional interface, it uses an additional encoder input for spindle feedback on position controlling.

The control cabinet should be protected with IP54. This type of protection is used as it does not affect the ventilation from within the control cabinet. But for the fan, the type of protection used is IP 24 because it is affected when it receives air, due to the path through which the air current passes. The operating conditions with which this drive controller can operate ideally has been stated by the manufacturer Bosch Rexroth, and should be followed to the letter. The permissible mean relative humidity is 70% or less at all times. The drive controller is not shielded from condensed water or any water in all its sorts. Condensed water produced from the cooling device can penetrate the controller and damage it, if the cooling device is not installed according to the manual.This unit can be shipped globally with a one-year warranty period from Wake Industrial.
