Product Description:

The DDC01.1-K200A-DC04-01-FW is a digital intelligent servo drive from Bosch Rexroth Indramat in the DDC Digital Intelligent Servo Drives series. It is used on automated machinery to supply speed- and torque-controlled power to synchronous motors in production lines. The drive includes an INTERBUS-S command module for fieldbus communication and uses digital servo feedback from the motor for closed-loop regulation. This combination allows the controller and motor to exchange command and feedback data while maintaining precise speed and torque response during changing load conditions.

The unit delivers a maximum armature current of 200 A, while its continuous current limit is 45 A under natural-convection cooling. During steady operation, it supports a continuous mechanical load of 7.5 kW, yet the electronics can provide up to 33 kW for short overloads. A power supply rated at 22.5 kVA is required for this operating range. S6-100 s duty permits 90 A with 15 kW of mechanical output, which gives the drive extra short-term capacity for acceleration or brief process peaks. Internally, the PWM inverter switches at 4 kHz and dissipates 500 W of heat to the surrounding air. Noise emission is standard for the 100 A to 200 A operating range, and the drive is function code 04, version 01, in Series 1, Version 1.

Braking energy is handled by a bleeder circuit rated for 0.25 kW continuously and up to 40 kW during short deceleration peaks, with an energy limit of 20 kWs. This arrangement helps control DC-bus voltage during rapid stops and supports short braking events without an external resistor. The housing is sealed to IP65, which protects the electronics against dust ingress and low-pressure water jets. An internal power-loss monitor works with the switching stage to manage thermal loading during cyclic duty. This helps the power section remain stable when the connected axis is repeatedly accelerating, running at speed, and slowing to a stop.
