Product Description:

The DDC01.1-K100A-DA07-00/S001 is a digital intelligent servo drive manufactured by Bosch Rexroth Indramat for the DDC Digital Intelligent Servo Drives series. Serving as the power and control stage between a motion controller and an Indramat synchronous motor, it converts low-level commands into regulated three-phase output current. In automated lines, the unit supplies precise torque and velocity regulation for positioning tables, pick-and-place actuators, and other production axes. It is suited for machinery that depends on repeatable closed-loop motion and stable axis response. By regulating motor current in real time, the drive supports controlled acceleration, deceleration, and steady-speed operation.

Logic circuitry in the drive is energized by 24 V DC and draws 150 mA of control input current, while field diagnostics place a 4 mA load on the same supply rail. The power stage accepts 3 × 230 V AC (+10 %/-15 %) mains and can continuously provide 100 A to the connected motor. Heat is removed through natural convection air cooling, so no auxiliary fan is required. The housing carries an IP65 protection category that resists dust and low-pressure water jets. Separate control and power inputs allow the electronics to remain active for monitoring and orderly enable timing before the inverter section is driven. Function code 07 and series 1 identify the control configuration, an on-pulse width of 100 ms governs enable timing, and a Ud contact threshold of 200 V protects the DC link.

The command module uses an analog interface so external controllers can send velocity or torque references as analog signals, and the internal buffer reproduces them on a ±10 V diagnostic output for monitoring. This arrangement suits systems that use conventional analog command channels instead of a digital network command path. Overcurrent protection trips at 1.5 × rated current, shutting down the inverter before semiconductor damage occurs, while an overvoltage threshold of 475 V disconnects the DC bus during regenerative events. These protective actions help limit stress on the power section during abrupt load changes and braking events. Version 1 hardware uses noise-immune differential signaling for diagnostics, which helps preserve signal integrity in industrial electrical environments.
