Product Description:
The Bosch Rexroth Indramat DKC05.3-016-7-FW is a drive controller in the DKC Drive Controllers series. As an EcoDrive unit, it regulates current and voltage delivered to AC servomotors, enabling coordinated motion axes in automated machinery and material-handling stations. This role allows the drive to translate control commands into stable motor behavior during positioning and speed-regulated operation. Communication to the higher-level CNC or PLC is routed through a 9-pin D-Sub male connector that is allocated as interface option 05.
This Version 3 design accepts a nominal DC-bus voltage of 700 V and provides a steady output current of 16 A to the connected motor windings. During high-frequency control loops, the inverter can modulate up to 800 Hz at an 8 kHz switching rate, allowing finer torque resolution on fast-responding axes. Internal electronics draw 16 W of control power, which is low enough for shared cabinet supply arrangements. A soft-start resistor of 240 Ω limits inrush when the DC link is charged, helping reduce stress on upstream components during power-up. Energy is stored in a 0.135 mF capacitor bank and can be replenished through a maximum charging current of 2 A. The mechanical layout is compact, with an overall depth of 229 mm, a height of 287 mm, and a width of 65 mm, so the unit fits densely populated drive rows.
The drive body has a mass of 3.2 kg while still housing bleeder circuitry capable of dissipating 2.7 kW of regenerated energy during dynamic braking. This braking capability helps absorb energy returned from the motor during deceleration instead of sending it back into the cabinet wiring. At a 4 kHz switching frequency, the output stage can supply up to 6 A for short-term demand on medium-inertia axes. Continuous operation produces 80 W of heat, so forced-air cabinet ventilation is recommended to keep semiconductor junctions within limits. Adequate airflow also helps maintain stable thermal conditions when the drive operates in compact enclosures.
