Product Description:

Manufactured by Bosch Rexroth Indramat, the DDC01.1-K100A-DL28-01-FW belongs to the DDC Digital Intelligent Servo Drives series. It is a digital servo drive intended to coordinate AC servo motors in automated assembly, packaging, and material-handling stations. The drive’s integrated control hardware executes closed-loop motion commands so that axes follow programmed profiles without relying on an external motion PLC. This arrangement reduces panel space and simplifies wiring in installations that require precise single-axis positioning and fast updates from feedback devices.

The drive operates from a three-phase input of 3 × 230 VAC at 50/60 Hz. A continuous output of 100 A is available, while an electronic trip activates at 1.5 × rated current to protect power semiconductors during short circuits or stalled rotors. The housing has an IP65 rating, allowing direct mounting outside a cabinet, and cooling is handled by natural convection over the finned surface. Internal leakage current exceeds 3 mA, so a protective earth connection is mandatory. Drive logic communicates through a V24, RS-232C serial interface, and motor position is returned through digital servo feedback.

The energy section trips on a DC-bus ceiling of 475 VDC and shuts down if the link falls below 200 VDC, preventing unstable regeneration or undervoltage faults. Application logic can store up to 3000 blocks of positioning code, and the holding brake on a connected motor is released with +24 VDC supplied from the auxiliary connector. The single plug-in command module supports single-axis positioning functions, and five rear slots labeled U1 through U5 accept additional option cards when more I/O is required. Noise emission is standard for the 100 A to 200 A range, and the natural-convection design avoids the use of extra fans.
