Product Description:

The DKS01.1-W030B-RS18-02-FW is a digital servo drive manufactured by Bosch Rexroth Indramat for the DKS Intelligent Digital Servo Drives series. The unit converts three-phase mains power into a regulated DC bus and a pulse-width-modulated output so connected synchronous servomotors can follow commanded speed or torque profiles. In automated assembly lines and material-handling systems, it links PLC setpoints to mechanical axes and supports precise, repeatable motion in multi-axis equipment. An integrated braking function helps manage returned energy during deceleration and keeps the DC bus within its intended operating range.

This drive accepts an input of 3x 230 V AC with a tolerance of ±10%, allowing direct connection to low-voltage factory power systems. A continuous output capability of 30 A provides the long-term phase current limit, while the converter stabilizes the bus at 300 V DC to support rapid acceleration and controlled motor response. Power transistors switch at 18 kHz, which reduces audible noise and improves current smoothing during operation. The internal bleeder network dissipates 0.3 kW continuously and can handle peaks up to 5 kW during braking events. Heat is removed through the rear heat sink, and the low-noise design makes the drive suitable for installation in occupied work areas.

The drive can operate in control cabinets with ambient air up to +55 °C; above that temperature, output derating is required to protect the semiconductors. Operation is permitted up to 1000 m above sea level without a reduction in capacity. A protection class of IP10 blocks only large foreign objects, so the unit should be installed inside an enclosure when fine dust or liquid exposure is possible. Storage temperatures from -30 °C to +85 °C are permitted, which supports shipment and long-term storage between periods of use.
