Product Description:

Bosch Rexroth Indramat manufactures the DDC01.1-K150A-DG04-00 drive within the DDC Digital Intelligent Servo Drives series. This unit is a digital intelligent servo drive that interfaces with servo motors to regulate speed, torque, and position in automated machinery. By converting three-phase supply energy into pulse-width-modulated output, it supports precise closed-loop motion control on production lines, packaging stations, and handling equipment. It can serve as the power stage between the incoming supply and the motor, translating control commands into regulated current for dynamic acceleration and steady running. Its control architecture is suited to coordinated axis movement where repeatable response and stable feedback processing are required.

The drive accepts a three-phase AC mains input and delivers a rated current of 150 A to the connected motor. Internally, switching devices operate at a carrier frequency of 4 kHz, allowing fine voltage resolution while keeping acoustic noise within the standard range for drives in this current class. During continuous operation, the electronics dissipate up to 500 W, so the aluminum housing relies on natural convection air cooling to maintain temperature. The enclosure is rated IP65, which helps protect internal components against dust and low-pressure water jets. Position and velocity loops are closed in real time through digital servo feedback. G-code programming support allows contour-based motion sequences for machines that require path control rather than simple point-to-point movement.

For transient deceleration events, a bleeder circuit rated at 0.25 kW converts regenerated energy into heat and helps prevent overvoltage on the DC link. Control flexibility is extended by five plug-in slots that accommodate the DLC 1.1 positioning module and the DSM 2.1 software module, both used with Function Code 04. These modules provide interpolated positioning and diagnostic functions while leaving additional slots available for communication or I/O expansion. The modular slot arrangement allows the control layout to be tailored to application needs without changing the base drive housing. The drive is Series 1 and Version 1.
