DDC01.2 stands for DDC series with hardware version V1.2, IP65 air-cooled platform. N200A means peak output current 200 A with natural convection cooling. DS01a: D refers to digital encoder/resolver feedback, S stands for SERCOS fiber-optic bus interface, 01a is upgraded version of standard DS01 with improved electromagnetic compatibility. No FW suffix indicates firmware needs separate installation.

Input power 3-phase AC 220–230 V ±10%, 50/60 Hz, 22.5 kVA. Continuous output current 45 A, peak output current 200 A. Continuous rated power 7.5 kW, peak power 33 kW. PWM carrier frequency 4 kHz. Integrated braking unit with peak power 40 kW and continuous power 1.0 kW. Protection class IP65. Operating temperature +5 °C to +45 °C for rated operation, derating required above +55 °C. Weight approx. 22 kg, dimensions 517 × 165 × 298 mm. No performance derating below installation altitude 1000 m.

Motor feedback port supports digital encoder and resolver, compatible with MDD and MKD series servo motors. Control interface is dedicated SERCOS fiber-optic bus for high-speed real-time command transmission. RS232 debug port for parameter setting via DDS2PC software. Equipped with 8 digital inputs and 8 digital outputs at 24 VDC level. U1 to U5 slots are reserved for optional fieldbus modules.

Supports position, speed and torque three-loop control modes. Retains basic motion functions including single-axis positioning and master-slave follow-up. Optimized circuit design delivers stronger anti-interference capability for harsh industrial environments. Built-in regenerative braking unit ensures stable energy dissipation during deceleration. Integrated fault diagnosis and alarm system. Parameters are stored in non-volatile memory without loss after power cut.

Machine tool feed axes and spindles equipped with SERCOS bus system. Multi-axis synchronous production lines in packaging, textile and general automation industries. On-site replacement and maintenance of original DDC series servo drives. Matched with Rexroth MDD200A and MKD200A high-power servo motors.

DS01 is standard SERCOS version for general industrial environments. DS01a adds enhanced anti-interference circuits, suitable for working sites with strong electromagnetic interference.

This unit is delivered without preloaded firmware. Corresponding dedicated firmware must be purchased and programmed before commissioning.
