Product Description:

The DDC01.1-K050A-DL01-01-FW is a digital intelligent servo drive manufactured by Bosch Rexroth Indramat as part of the DDC Digital Intelligent Servo Drives series. In multi-axis assemblies, it provides closed-loop current and velocity control so an attached motor can follow programmed motion profiles in automated assembly, material transfer, and other industrial positioning processes. The unit is intended for applications that require coordinated motion with consistent speed regulation and controlled torque output. Its layout supports installation close to the machine when a compact decentralized drive arrangement is preferred.

This drive delivers a continuous output of 50 A and is housed in an IP65 enclosure that permits direct machine mounting without a separate cabinet. Protective limits include an overvoltage trip set to 475 V, an undervoltage threshold of 200 V, and an overcurrent trip that activates at 1.5 × rated current. The unit also provides an over-temperature warning 30 seconds before shutdown, allowing the control system to react before thermal protection removes power. After a stop command, the power stage removes torque after 500 ms. Product identification includes Function Code 01, Function Code Version 01, Series 1, and Version 1.

Cooling is provided by natural convection air cooling, so no fan or liquid circuit is required. Motion commands are handled by a single-axis positioning module, and field wiring terminates on the DEA 4.1 I/O board for limit switches and sensor inputs. Motor rotor angle is returned through digital servo feedback to maintain closed-loop operation during speed and position control. Integrated brake control supplies 24 V DC to release the motor brake, applies the brake when speed drops below 10 rpm, and limits engagement delay to 400 ms. Mechanical brake wear is rated for 20,000 revolutions, and torque is also cut off if the supply voltage falls below the permitted range.
