Product Description:

The DDC01.2-N050C-DL20-01-FW is an AC servo drive produced by Bosch Rexroth Indramat within the DDC Digital Intelligent Servo Drives series. It is supplied as Series 1, Version 2 hardware with Function Code 01. Its integrated DL20 command module performs single-axis positioning, allowing point-to-point moves to be executed from stored parameters without an external motion controller. This arrangement lets the drive handle localized motion tasks directly at the axis. The unit regulates speed, torque, and position for permanent-magnet motors used on packaging, handling, and machine-tool axes that require rapid, repeatable motion.

The power stage delivers a continuous mechanical output of 4 kW and supports a motor phase current of 50 A, while drawing 6 kVA from the mains at full load. Pulse-width modulation switches at 8 kHz to reduce torque ripple without excessive semiconductor loss. Standard cooling channels move air across internal heat sinks, and the basic unit weight is 21 kg for cabinet or machine-mounted installations. Digital servo feedback from the connected motor closes the velocity and position loops, allowing the drive to respond accurately to changing load conditions during acceleration, steady running, and stopping. The housing has an IP65 protection rating, which helps keep dust and low-pressure water away from the electronics.

Mechanical load capability rises from the continuous rating to 8 kW for short intervals and peaks at 8.5 kW during initial acceleration. During deceleration, kinetic energy is routed to a bleeder rated at 0.25 kW continuous and 10 kW peak, with total absorption limited to 5 kWs. Steady-state dissipation is held to 500 W, which must be considered when arranging enclosure ventilation and heat removal. The drive operates in ambient temperatures up to 55 °C and at elevations up to 1000 m under standard cooling, so it can be mounted near the machine without auxiliary climate control.
