Product Description:

Bosch Rexroth Indramat manufactures the DDC01.1-K050A-DL08-01-FW as an intelligent servo drive in the DDC Digital Intelligent Servo Drives series. The unit incorporates a single-axis positioning command module for closed-loop motion tasks, so it can manage axis movement directly within automated equipment. Position data is accepted through the DFF01.1 encoder interface, giving the controller the feedback it needs to track commanded motion accurately. Process signals are exchanged over the DEA04.1 I/O interface, allowing the drive to interact with surrounding machine logic in industrial automation cells. The integrated interfaces keep feedback and process connections separate, which helps the drive handle motion commands and machine status signals at the same time.

The drive delivers a continuous output of 8.5 kW and draws a rated current of 50 A, placing it in the range used for medium-power servo axes. Under these conditions, it dissipates 300 W of internal power loss and switches the motor phases at 4 kHz to control current flow to the motor. The housing is rated to IP65, allowing direct machine mounting without an additional enclosure in areas exposed to dust or low-pressure water jets. Noise emission is standard, and operation is permitted up to 1000 m above sea level on series 1, version 1 units that use digital servo feedback. The stated altitude limit supports reliable installation where air density is lower than at sea level.

The electronics are cooled by natural convection air cooling, so heat is removed without external blowers or liquid-cooling hardware. During rapid stops, the controller can absorb a maximum regenerated energy of 4 kWs before the excess energy must be diverted away from the DC link. If that threshold is exceeded, power is transferred to a resistor that withstands a short-term load of 10 kW. Application logic is stored in nonvolatile memory with a capacity of 3000 sets, which allows multiple operating records to remain available after power is removed.
