Product Description:
The Bosch Rexroth Indramat RD52.2-5B-007-L-A2-FW is a drive controller within the RD 500 Drive Controllers series. It is intended to regulate three-phase motors in automated machinery, matching torque and speed to process requirements. By converting fixed-frequency line power into a variable output, the unit becomes a central component of closed-loop motion systems used in packaging, material handling, and other factory equipment. This arrangement allows the motor to respond accurately to changing load conditions and commanded speed changes.
At the input, the unit accepts a three-phase AC supply and operates within a line window centered on 500 V. Internally, it modulates the stator currents using field-oriented vector control, giving the attached motor full torque at low speed and precise dynamic response. The power section is rated for 7.5 kW, so it can drive medium-frame pumps, fans, or conveyor motors without derating. To remove heat from the semiconductors, the housing relies on forced-air cooling; mounting clearance must allow unobstructed airflow through the integrated fan and exhaust passages. This control method also supports stable running when the load changes during operation.
Short-term braking energy is dissipated by the integrated built-in brake chopper, eliminating the need for an external resistor assembly in most applications of this power class. Control electronics can be supported by external standby power, allowing parameter retention during line interruptions, while the starting lockout feature helps prevent unintended motor energization after a fault reset. This version is design generation 2 and works with current RD-series option cards. It also uses the same mounting dimensions and diagnostic menu structure found across the range, which keeps installation layout and routine operation consistent. That consistency is useful when the controller is installed alongside other RD-series units in the same cabinet.
