Product Description:
The DDC01.2-N050C-RL20-01-FW is a digital intelligent servo drive manufactured by Bosch Rexroth Indramat and assigned to the DDC Digital Intelligent Servo Drives series. The unit combines a power inverter with a single-axis motion controller, providing regulated torque and speed control for synchronous motors used in automated assembly lines, material handling carts, and process equipment. Integrated resolver feedback supplies real-time rotor position data so the internal control loops can execute precise positioning and velocity profiles without depending on an external motion controller. This arrangement keeps power conversion and axis control in one housing for compact machine integration.
Incoming power is supplied from a three-phase 230 V AC line and is converted into a controlled output that can deliver up to 50 A of continuous current to the motor windings. The analog command stage offers a differential range of ±10 V and can drive loads up to 4 mA, allowing direct connection to PLC analog cards. Because the command input is differential, it can better resist common electrical noise in industrial cabinets than a single-ended signal line. A bleeder circuit engages when the shared DC link reaches 75% of its design limit to dissipate regenerative energy. Standard cooling draws cabinet air through the heat sink fins, and the enclosure has an IP65 rating that helps protect the electronics from dust and water jets. Resolver feedback, a V24/RS-232C service port, and the standard reduced-noise profile complete the electrical interface.
The housing measures 635 mm in height, 220 mm in width, and 298 mm in depth. A minimum free-air gap of 300 mm is recommended above and below the unit to maintain cooling airflow. A permissible DC bus level of up to 745 V allows short line surges without triggering a fault. The single-axis positioning command module uses Function Code version 01, and the drive is Version 2. These dimensions should be considered when placing adjacent modules and planning cable routing inside the cabinet.
