The RS51.1-4G-006-L-V1-FW/S117, Bosch Rexroth Indramat, RD 500 Drive Controllers module delivers precision motion control for high-speed grinding spindles. Engineered for industrial automation, this robust drive converter incorporates U/f curve control to optimize torque response across variable loads. A compact footprint houses advanced power electronics and a built-in 24 V standby power module, ensuring continuous device readiness. Integrated monitoring interfaces allow seamless parameter adjustments via standard automation networks.
Designed around a Nominal Connecting Voltage of 3 x AC 380-480 V, the unit offers Rated Power of 6 kVA with a Rated Current of 10 A and a Nominal Current of 8 A. During peak demands it supports a Peak Output of 7.5 kVA and sustains Continuous Output of 5 kVA. The drive’s Cooling Mode is Forced air cooling, while an internal Brake Chopper & Resistor assembly protects against over‐temperature and regenerative surges. Additional specs include a voltage tolerance of ±10%, an operational Frequency Range of 0–2000 Hz, and compliance with environmental class 3K3.
With its modular design and Unit Type optimized for high-speed grinders, the RS51.1-4G-006-L-V1-FW/S117 integrates into existing Rexroth drive networks with minimal configuration. Forced convection cooling and the built-in surge protection enhance reliability under continuous duty cycles. Ideal for precision machining centers and automated grinding lines, this controller ensures uptime, precise speed regulation, and simplified maintenance.
