Product Description:

The DDC01.2-N050C-DS46-02-FW is a drive controller produced by Bosch Rexroth Indramat within the DDC Digital Intelligent Servo Drives series. It belongs to hardware series 1. The unit functions as a power stage that modulates three-phase motor voltage and current to execute velocity, torque, and position commands in automated machinery. By integrating the drive, feedback evaluation, and fieldbus communication into a sealed housing, it supports compact mounting on machines where decentralized motion control helps reduce cabinet space and wiring complexity.

At the heart of the drive, a SERCOS Interface command module exchanges cyclic setpoints and status with higher-level controllers. The power section delivers a rated motor current of 50 A and can sustain a continuous mechanical output of 4 kW while drawing 6 kVA from the mains. For fine torque resolution, it switches at a PWM frequency of 8 kHz. Thermal management relies on standard cooling and an internal bleeder that dissipates 0.25 kW during regenerative braking. When loads spike, the short-term mechanical capability rises to 8 kW, and noise emission is listed as Standard (50 A) Reduced Noise. The enclosure rating is IP65, allowing installation directly on the machine frame, and motion feedback is processed through digital servo signals from the motor encoder.

Energy returned from rapid deceleration is managed by a bleeder resistor that can momentarily absorb up to 10 kW, supporting a maximum regenerated energy of 5 kWs before external dissipation is needed. The drive tolerates usable peak mechanical loading of 8.5 kW during demanding motion cycles. Field wiring is simplified by permitting encoder leads up to 75 m in length, and the assembly weight of 21 kg eases panel installation without extra support rails. Standard cooling maintains rated performance while the internal design keeps bleeder noise low.
