Product Description:

The DKS01.1-W100A-DL43-01-FW is a digital servo drive developed by Bosch Rexroth Indramat for the DKS Intelligent Digital Servo Drives series. Acting as the axis interface between an MDD servo motor and a CNC or PLC, it converts command data into controlled three-phase power while monitoring real-time position through digital servo feedback. In automated assembly lines, packaging units, and material-handling systems, the unit supplies regulated current and voltage so the driven motor can follow precise speed, torque, and position profiles. This arrangement allows the drive to handle the motor control task directly at the axis, which supports stable motion during changing loads and repeated cycle sequences.

During continuous operation, the drive can deliver a rated output of 100 A, which is the maximum RMS phase current the internal power stage can supply without exceeding thermal limits. It accepts an input supply of 3 x 230 V AC from a standard industrial distribution network, and these three phases are rectified to a 300 V DC bus that feeds the IGBT bridge. Pulse-width modulation is generated at 4 kHz, a switching frequency chosen to balance current ripple against switching loss. For analog control loops or diagnostic tasks, the front panel provides a buffered ± 10 V DC measurement channel, allowing process values to be sent to an oscilloscope or external controller with a permissible load of 100 mA. This signal path is useful when checking response behavior during setup or when tracing command and feedback relationships during machine operation.

Excess regenerative energy is drained by an integrated bleeder resistor able to dissipate 0.5 kW continuously and absorb surges up to 18 kW for short braking intervals, which protects the DC bus when high-inertia MDD motors decelerate. At peak mechanical demand, the power section can momentarily draw 28 A from the mains, and worst-case conversion losses are limited to 480 W, figures that are important for panel cooling and fuse sizing. The drive relies on heat dissipation through its housing rather than forced internal airflow, so the cabinet layout should allow that heat to move away from the unit effectively. It carries an IP 10 protection class, emits standard noise levels, and is version 1.
