RAC 4.1-400-460-L00-W1

Product Description

Indramat is a leading machine, equipment, and device manufacturer due to its cutting-edge manufacturing process. It manufactures intelligent, high-quality, and reliable products. The RAC  4 Main Spindle Drive Controller series offers outstanding features and applications.

The RAC 4.1-400-460-L00-W1 main spindle drive controller can digitally control two motors, an Indramat asynchronous main spindle motor and a frameless spindle motor with up to 93 kW continuous power motor output. The RAC 4.1-400-460-L00-W1 features drives with high stiffness and extensive range of speed variation, making it compatible with automated machine tools. Its AC-main spindle drive also has an internal automatic position control loop with a maximum resolution of 1/4 000 000 revolutions. The main spindle drive has a high-resolution feedback that can control low speeds during the c-axis operation.

The RAC 4.1-400-460-L00-W1 can be connected to three-phase supply networks. The electrical connections of the main spindle drives are also standardized and categorized into the following: feedback and NC connections, power connections, and controller-dependent connections. In case a power failure occurs, the RAC 4.1-400-460-L00-W1 drive will use its D.C current braking system to shut down the main spindle. It also offers an optional additional interface. In considering the structural integrity of the main spindle drive controller, the following factors must be considered: the operating conditions, the mechanical data, thermal data, the electrical data, and the technical data or the type code. The maximum mounting altitude the RAC 4.1-400-460-L00-W1 is 1000m above sea level.

The RAC 4.1-400-460-L00-W1 can be cooled with air flowing inside or outside of the control cabinet. The heat sinks are built in every RAC 4 unit. The principle of the heat exchanger is applied in the control cabinet ventilation. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
