RAC 3.5-100-460-A00-Z1-220
The RAC 3.5-100-460-A00-Z1-220 is a main spindle drive controller developed by Bosch Rexroth Indramat, requiring a minimum of 160mm clearance for both the top and bottom when installed inside a sealed enclosure. Designed for a maximum operating temperature of 45° without data deration, this unit also has a control voltage rating of 230VAC +/-10% and a current rating of 100A. With a weight of 49kg, the RAC 3.5-100-460-A00-Z1-220 features an analog speed setpoint of +/-10V at its X4 connector for complex CNC control connections and must be installed at elevations no higher than 1,000m above sea level. This IP 10-protected unit should be vertically installed, efficiently dissipating operating heat via its built-in heatsink, and comes with an IP 24-rated fan. Its integrated electrical connections and plug-and-socket connectors streamline the process of integrating the controller with the sealed housing's control circuits. With no additional encoder input or additional interface, this unit does provide an inbuilt bleeder for braking during mains voltage failure. Despite the lack of continuous regeneration, it can produce peak regeneration output of up to 26kW for 5 seconds.
