Product Description:

The RZR01.2-RD52-0610-P-M-FW is a Frequency Converter Controller manufactured by Bosch Rexroth Indramat for the RZR Frequency Converters series. Serving as a motor inverter, it converts the DC bus energy of a multi-axis installation into a controlled three-phase output that drives induction or synchronous machines. Used in industrial automation, the unit forms the power stage that links higher-level motion commands to the mechanical shaft, allowing precise speed and torque control in conveyor lines, winding equipment, and material-handling stations.

Control electronics are supplied with 24 V ± 5%, so the converter can be integrated with low-voltage logic circuits without additional conditioning hardware. Drive regulation relies on field-oriented vector control; this algorithm resolves stator current into torque-producing components and supports fast response during load changes. The power section uses a parallel circuit layout, permitting current to be shared across internal paths and minimizing conductor losses. Under rated operating conditions, the module delivers up to 610 A to the connected motor, supporting high starting torque or rapid acceleration cycles. A housing rated IP20 provides finger protection for cabinet-mounted installations where forced ventilation is available.

Thermal limits permit continuous operation between 0–40 °C, matching typical control-room conditions and avoiding derating within that span. The unit meets 3K3 (DIN IEC 721-3-3) conditions, so it can be used where moderate dust and low condensation may be present. The assembly weighs 6.5 kg, which keeps handling manageable during cabinet installation. During standby or when only the logic circuitry is active, the unit draws a maximum of 12 A, a value that helps with auxiliary power supply sizing and cabinet heat planning.
