Product Description:

The DDC01.1-K050A-DG04-00 is a digital intelligent servo drive produced by Bosch Rexroth Indramat in the DDC Digital Intelligent Servo Drives series. This unit is version 1 from series 1. It supplies regulated three-phase power and executes motion-control algorithms, forming the link between a synchronous servo motor and the machine PLC in automated assembly, packaging, and material-handling stations. The drive also handles current regulation, speed control, and position-related processing inside a single housing for coordinated axis operation.

The drive accepts an input of 3 x AC 220/230 V across three power phases and delivers up to 50 A of continuous motor current. Host communication uses an RS232 port, while two analog outputs transmit process values to external indicators or controllers. This arrangement allows the unit to exchange serial data and provide operating signals for monitoring functions at the same time. The base chassis contains 4 plug-in slots, allowing configuration flexibility with modular option cards. Environmental sealing is rated at IP65, permitting on-machine mounting without an external cabinet. Current supervision trips the inverter at 75 A, while natural convection air cooling removes heat and digital servo feedback from the attached motor supports precise position and velocity loops.

Integrated braking control governs deceleration during stopping. When rotational speed falls to 10 rpm, the drive waits 0.4 s before energizing the motor brake, which helps reduce mechanical shock at low speed. DC-bus monitoring opens the power switches at an over-voltage threshold of 475 V, protecting the semiconductors from line surges or regenerative events. By separating the speed threshold, delay time, and DC-bus shutdown function, the unit manages braking and electrical protection in a controlled sequence. These protection functions support predictable stopping behavior and stable operation during repeated machine cycles.
