Product Description:

The DKS01.2-W100A-DL02-01-FW is a digital servo drive built by Bosch Rexroth Indramat for the DKS Intelligent Digital Servo Drives series. As a closed-loop amplifier, it regulates current and velocity for synchronous or induction motors in automated machinery. Industrial controllers send motion commands to the drive, and the unit converts those commands into precisely timed switching patterns for connected axes. This places the DKS01.2-W100A-DL02-01-FW at the center of material handling lines, packaging machines, and other equipment that depends on coordinated motion. Because the control loop is handled inside the unit, the connected motor can respond quickly to changing load conditions and commanded speed changes during repetitive machine cycles. It is suitable for indexing axes, feeders, and transfer mechanisms where repeatable acceleration and deceleration are required.

On the control side, the drive provides 22 assignable inputs and 27 assignable outputs, allowing machine logic to exchange ready, fault, enable, and interlock signals directly with the motion axis. The power section accepts 3 x 230 V AC from the supply and internally converts it to a 300 V DC bus that feeds the IGBT bridge. Carrier pulses are modulated at a 4 kHz PWM frequency, which helps limit motor acoustic noise while maintaining efficient switching behavior. The DLC 1.1 command interface card is mounted on the front panel and links the drive to higher-level motion controllers, while the integrated DSF resolver channel closes the position loop. This arrangement reduces the need for separate signal-conditioning modules in compact control cabinets.

The drive has a rated current of 100 A, so it can energize medium-frame servomotors without external boosters. Regenerative energy is dissipated through a bleeder resistor that handles 0.5 kW continuously and tolerates up to 18 kW during rapid deceleration. Overall conversion losses are specified at 480 W, and that heat is removed through natural cooling because no fan is installed. The electronics meet IP10 protection, so the unit must be mounted inside a cabinet with filtered airflow, and noise emission is standard for this power class. Cabinet mounting is important because the open housing depends on the enclosure for touch protection. The unit is version 2 in this product line.
