Product Description:

The DDC01.1-F150A-RL08-01-FW servo drive is produced by Bosch Rexroth Indramat as a member of the DDC Digital Intelligent Servo Drives series. It is intended to regulate rotary motors in automated machinery, combining power conversion, motion control, and diagnostic functions so a PLC can position a single axis with high repeatability.

This model draws power from a supply rated at 220 V AC and is designed for Three-Phase AC distribution networks, allowing symmetric loading of industrial mains. The internal power section can deliver a continuous output of 150 A, a capacity suited for medium-to-large servo motors that demand high peak torque. Heat generated by those currents is extracted through a Liquid cooling circuit, eliminating the need for large air channels inside the cabinet. The housing carries a global protection category of IP65, and the X7, X5, and X8 connectors share the same ingress rating so field wiring can be exposed to wash-down areas without additional junction boxes. An integrated command module provides single-axis positioning, while the built-in mains contactor and dynamic braking resistor shorten installation time and support energy-controlled stops when power is removed.

Peripheral requirements focus on machine safety and service access. The incoming feeder must be safeguarded by a slow-blow fuse of 16 A, and the cabinet designer must leave at least 300 mm above the drive for the liquid radiator’s warm air outlet. Motor position is returned through a Resolver interface, enabling reliable speed and angle feedback in electrically noisy environments. Control electronics receive auxiliary power from the internal +24 V rail, where the user may tap a logic signal that is limited to 100 mA Max to drive sensors or status lamps without overloading the supply.
