Product Description:

The DDC01.1-K050B-DL02-01-FW belongs to the DDC Digital Intelligent Servo Drives series from Bosch Rexroth Indramat. It is a digital intelligent servo drive used to execute closed-loop motion tasks for single rotary axes in automated machinery. Its integrated command module supports single-axis positioning, so the unit can process motion profiles internally and send precise current commands to a connected motor through the digital servo feedback interface. This arrangement allows the drive to handle local motion control without relying on a separate external positioning module for routine axis movement.

The drive delivers a continuous three-phase output of 4 kW while supplying a rated phase current of 50 A. Switching of the output stage occurs at a pulse-width-modulated carrier of 16 kHz, which helps tighten current regulation and reduce motor noise. A sealed housing with a protection rating of IP65 shields the electronics from dust and low-pressure water jets, and heat is removed by natural convection air cooling. The enclosed design allows the unit to be mounted close to the machine process in locations where basic environmental protection is needed. Electrical service connections are sized for 24 V control power, and each modular I/O board provides 15 digital inputs and 16 digital outputs to the machine controller. Under nominal load, the unit dissipates 300 W, maximum apparent input power reaches 6 kVA during dynamic operation, and the total weight is 21 kg. The function code is 02 with version 01, and the drive is series 1 and version 1.

An internal braking resistor continuously absorbs 0.25 kW and can accept peaks up to 10 kW during aggressive deceleration. The energy that can be returned to the bleeder without triggering overvoltage is limited to 4 kWs per stop event. Program memory allows storage of 3,000 motion data sets that are transferred over the dual serial interface RS-232/RS-485. Stored motion records support repeated positioning sequences, and each axis module draws its 24 V logic supply from the same source that feeds the I/O, which simplifies cabinet wiring.
