Product Description:

The DDC01.2-N100A-DL43-01-FW is a digital intelligent servo drive designed and manufactured by Bosch Rexroth Indramat for the DDC Digital Intelligent Servo Drives series. It combines the power stage, a single-axis positioning command module, and a digital servo feedback interface in one housing to provide closed-loop control for synchronous motors in automated production lines. This integrated layout reduces the need for separate external modules and helps keep cabinet arrangements more compact. It is intended for applications that require coordinated motion, controlled acceleration, and stable servo response during continuous industrial use.

This unit sustains a continuous mechanical load of 6 kW, enabling stable torque delivery during prolonged duty cycles. It can supply a rated motor current of 100 A, while the output transistors switch at a carrier frequency of 4 kHz to balance switching losses and acoustic performance. Thermal dissipation is limited to 500 W and is handled by standard cooling that channels cabinet air through the heat sink. When the axis accelerates at maximum demand, the upstream supply must accommodate up to 18 kVA. Additional characteristics include standard noise emission for 100 A to 200 A models, dimensions of 635 mm high by 298 mm wide by 220 mm deep, and a mounting arrangement that supports installation without extra fan trays.

The power stage delivers a usable peak load of 17 kW for rapid speed changes, and its bleeder circuit can absorb up to 20 kW so DC-bus voltage stays within limits. During braking, the drive redirects as much as 10 kWs of regenerated energy into the resistor bank. The enclosure has an IP 65 rating, which permits machine-side mounting when the installation altitude does not exceed 1000 m. The product is series 1 and version 2, with function code version 01. PWM timing, cabinet-air cooling, and the stated altitude limit should be considered during system integration.
