Product Description:

The DDC01.1-K050A-DL20-00 is a servo drive produced by Bosch Rexroth Indramat and is part of the DDC Digital Intelligent Servo Drives series. It combines power conversion with a built-in positioning command module, so the unit can run single-axis motion profiles without an external controller. This arrangement reduces dependence on higher-level control hardware for basic indexed moves and lets the drive execute stored positioning tasks directly at the axis. Digital servo feedback from the connected motor is processed inside the drive, allowing closed-loop positioning for pick-and-place systems, packaging stations, and other automated axes. Its IP65 enclosure protects the electronics, and natural-convection air cooling allows direct mounting on a machine frame.

The drive delivers a continuous output of 25 A and can sustain momentary surges up to 50 A for rapid acceleration. That current reserve helps the axis overcome inertia during starts, reversals, and short positioning moves without immediately dropping back to continuous operation. Internal braking circuitry dissipates regenerated energy with a continuous bleeder rating of 0.25 kW, while short bursts are handled at 10 kW. During frequent deceleration, the intermediate circuit can absorb up to 5 kWs before thermal limits are reached. Pulse-width modulation switches at 8 kHz, and the integrated command module stores complex motion paths in a 3000-block program memory. This allows repeatable standalone sequences where stored paths are recalled by machine inputs instead of continuous external interpolation.

Total input demand is 6 kVA, so the supply and protective devices must be sized for that load. The inverter section uses pulse-width modulation to balance current ripple with switching losses and keep motor operation stable during changing load conditions. System protection is automatic: an overvoltage trip activates at 475 V, and undervoltage shutdown occurs below 200 V. These thresholds protect the power semiconductors when mains conditions fluctuate and help prevent unstable axis behavior during supply disturbances. The drive remains convection cooled, and the IP65 enclosure keeps dust and water spray away from the electronics during normal industrial operation.
