Product Description:

Bosch Rexroth Indramat builds the DKS01.1-W100A-DS01-00 as part of the DKS Intelligent Digital Servo Drives series. The unit is a digital servo drive intended to regulate the torque, speed, and position of servomotors in automated machinery. With a mass of 11 kg, it fits readily into control cabinets where compact motion control is required. By converting a three-phase supply into a pulse-width-modulated output, the drive supports closed-loop motion functions for packaging, material-handling, and assembly equipment. Its closed-loop design also helps the system correct for changing loads during acceleration, deceleration, and steady-state operation.

Electrically, the drive accepts a line supply of 3 × 230 V AC and internally maintains a DC bus at 300 V DC. Under continuous duty, it can deliver 50 A, while transient demands can be met with a peak of 100 A. A carrier frequency of 4 kHz shapes the PWM output, balancing acoustic behavior with switching losses. Dynamic braking energy is absorbed by an integral bleeder that tolerates surges up to 18 kW. The inverter draws power through a three-phase AC input, and its maximum apparent demand is 11 kVA for coordination with upstream protection devices. Heat generated by semiconductor switching is removed through the rear mounting surface, so panel layout should allow that heat to leave the drive body.

The regenerative resistor dissipates continuous braking energy at 0.5 kW, helping prevent bus overvoltage during repetitive decelerations. The converter releases 480 W as heat, and that value should be included when cabinet ventilation is planned. The housing carries an IP10 protection class, which blocks large solid objects but does not protect against water ingress, so the drive should be installed in an enclosed cabinet where dust or moisture may be present. Operation is permitted up to 1000 m above sea level without output derating. The standard noise emission level supports use near operator work areas.
