Product Description:

The DKS01.1-W100A-RL01-01-FW is a digital servo drive manufactured by Bosch Rexroth Indramat within the DKS Intelligent Digital Servo Drives series. Designed to energize and regulate synchronous motors, this unit combines current control, position loops, and machine I/O in one housing for industrial automation tasks that require accurate closed-loop motion on a single axis. Resolver feedback supports torque and velocity control, while integrated serial communication allows the drive to exchange operating data with higher-level equipment. The unit is version 1 and is intended for applications where compact axis control and direct signal handling are needed in the same device.

Power is supplied through 3 × 230 V AC mains at line frequencies from 50 to 60 Hz, and an internal rectifier converts this input to a 300 V DC bus for the output stage. The power section can deliver a continuous phase current of 100 A, which supports substantial servo motor torque during sustained operation. Parameterization and diagnostics are handled through a multi-device RS-232/RS-485 port, making it possible to connect the drive to controllers or service computers without additional interface hardware. The noise emission is standard, and heat from the switching section is removed by passive dissipation through the mounting plate rather than by forced-air cooling.

For auxiliary control tasks, the drive provides 7 software-assignable inputs and 11 assignable outputs, allowing external sensors and status signals to be processed directly by the unit. During deceleration, excess energy is diverted to an internal bleeder with 0.5 kW continuous capability and peak absorption up to 18 kW, which helps protect the DC link from overvoltage. Single-axis positioning operates with resolver feedback for commanded moves, and the housing is rated IP10 for installation inside a protected cabinet. Cooling relies on passive heat dissipation, so space around the enclosure should remain open enough for heat to leave the housing.
