Product Description:

The DDC01.1-K050B-DG02-00 is a digital intelligent servo drive manufactured by Bosch Rexroth Indramat for the DDC Digital Intelligent Servo Drives series. This Version 1 unit with Function Code 02 conditions and delivers regulated three-phase power to synchronous motors while processing digital servo feedback for precise closed-loop motion. Used in machine tools, material handling stations, and packaging equipment, the drive converts automation commands into accurate torque and speed changes for controlled axis movement. Its integrated control structure supports precise motor response during positioning and speed regulation. It is suited for coordinated motion tasks that require repeatable speed and torque control.

On the power side, the drive accepts a three-phase supply of 3 × AC 220/230 V at 50/60 Hz, and it can continuously conduct 50 A to the motor terminals. For transient events, the overcurrent trip interrupts output at 1.5 × rated current, while an internal monitor isolates the mains if the DC bus rises above 475 V. These limits help protect the converter and connected motor windings from electrical stress. During deceleration, kinetic energy can recharge the DC bus and help support the load. Noise emission remains reduced at the 50 A rating, which helps when the drive is installed near sensitive sensing devices.

The housing has IP65 protection, allowing direct mounting on machinery without a cabinet. Heat is removed by natural convection air cooling, so no external fan is required. Command modules use a logic supply of 24 V DC and draw 150 mA at the control input, and the same voltage releases the motor brake while energizing Bb contacts that switch 24 V DC at 1 A. Analog velocity or torque references up to ±10 V are provided through an output limited to 4 mA, while Ud relay contacts switch AC 250 V at 1 A for auxiliary functions. Digital servo feedback supports position loops, and the holding brake pad life is rated for 20,000 revolutions.
