Product Description

Indramat is a reputable manufacturer of machines, equipment, and other technologically-advanced products. The RAC 4 Main Spindle Drive Controller series has a wide-ranging application. It also has outstanding operation performance rating. The RAC 4.1-400-460-AP0-W1 offers intelligent digital control, high-stiffness, and a speed range that can keep up with constant power. The drive controller is compatible with asynchronous and frameless main spindle motors. It is also the best choice for machine tools that are numerically controlled.

The RAC 4.1-400-460-AP0-W1 with an AC-main spindle drive can perform C-axis operations accurately and precisely. The drive controller can control extremely low speeds as it acknowledges rotor position through a resolution of 1/4 000 000 revolutions. The drive controller can be directly connected to supply networks with 3*400V, 50Hz, +/-15% or 3*460V, 60Hz, +/-10%. Whenever braking occurs during emergency situations, the energy is regenerated. This energy is fed back into the supply network. The housing of the drive controller is built with a heat sink and a cooling fan for ventilation. The drive controller can be placed in areas with cold, moderate, and dry-warm climates. However, condensation should be prevented. The ideal operating conditions for the drive controller require a permissible ambient temperature range with rated data should be +5 … +45 °C.

The RAC 4.1-400-460-AP0-W1 produces external and internal power dissipation that depends on the workload. Entering and changing the parameter values can be done on the keypad located on the control panel. Defining a customer-specific programming module for larger series is possible upon request from Indramat. Mounting and assembling the drive controller can be done seamlessly with the help of guidelines and instructions provided for by Indramat. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
