Product Description:

The DKS01.1-W100A-DA01-00 is a digital servo drive manufactured by Bosch Rexroth Indramat as part of the DKS Intelligent Digital Servo Drives series. It rectifies a three-phase 230 V AC mains feed and delivers controlled output current to matched servo motors, allowing closed-loop speed and position control in automated assembly cells, material-handling gantries, and other motion platforms. By integrating drive electronics, regenerative braking circuitry, and a resolver interface, the unit provides the power and feedback processing required for precise axis regulation while occupying minimal panel space. This arrangement lets a single module manage acceleration, steady-speed operation, and deceleration without separate feedback hardware.

This model draws energy from a 50/60 Hz network and will accept command frequencies up to 60 Hz. Inside the power section, a DC link held at 300 V DC is switched at a carrier of 4 kHz; the resulting PWM waveform shapes the motor voltage vector and helps reduce audible noise. A rated output of 100 A allows the drive to operate medium-frame servomotors under continuous production loads. Excess kinetic energy is dissipated by an integrated braking resistor that handles 0.5 kW continuously, which supports frequent stops on high-inertia axes without external hardware. The DSF resolver channel reports rotor angle directly to the digital control loop, allowing stable low-speed motion and responsive correction when load conditions change.

Installation conditions place clear limits on heat removal and enclosure use. Peak braking events are absorbed at up to 18 kW, so cabinet ventilation must remove the resulting heat from the fins used for passive cooling. Operation is permitted at ambient temperatures up to 55 °C when output current is derated and at elevations up to 1000 m without extra cooling provisions. Protection class IP10 provides only basic finger protection, so the drive should be mounted inside a closed electrical enclosure. Long-term storage is permissible up to 85 °C if moisture remains below condensation levels.
