RD52.1-7N-110-L-V1-FW/S129

RD52.1-7N-110-L-V1-FW/S129, Bosch Rexroth Indramat, RD 500 Drive Controllers. The RD52.1-7N-110-L-V1-FW/S129 is a high-performance DC supply inverter designed to control Bosch induction and synchronous motors with precision. It operates on a nominal connecting voltage of DC 530-670 V and delivers a continuous 110 kW of power using forced air cooling to maintain optimal thermal management. This inverter omits an internal brake chopper, relying instead on external braking solutions where required for your application’s dynamic demands.

Detailed specifications of the RD52.1-7N-110-L-V1-FW/S129 include selectable pulse frequencies of 4 kHz, 6 kHz, and 12 kHz, each offering rated motor outputs of 90 kW. The corresponding rated currents are 195 A at 4 kHz, 165 A at 6 kHz, and 80 A at 12 kHz, while output apparent power reaches 128 kVA, 109 kVA, and 53 kVA respectively. The unit requires a minimum airflow of 0.4 m³/s to sustain ambient temperatures within the 0…40 °C range. Environmental protection is provided by an IP20 enclosure with environmental class 3K3 per DIN IEC 721-3, and radio interference suppression A1 in accordance with EN 61800-3/EN 55011. Weighing 44 kg, it mounts easily inside control cabinets for enhanced dust and liquid protection.

Integration of the RD52.1-7N-110-L-V1-FW/S129 into existing automation platforms is seamless, with a standby power function powered by an external 24 V DC supply that allows parameterization, data read/write, and diagnostics even when line power is off. Its robust construction and precise control capabilities ensure reliable operation across demanding industrial environments. Backed by a one-year global warranty, this inverter is an ideal choice for applications ranging from material handling and processing to complex multi-axis servo systems.
