Product Description:

The DKS01.1-W100A-DS53-00-FW digital servo drive is manufactured by Bosch Rexroth Indramat and belongs to the DKS Intelligent Digital Servo Drives series. Serving as a closed-loop motion controller, it converts three-phase line power into controllable DC and PWM outputs so that industrial handling robots, packaging axes, and assembly stations can execute repeatable velocity and position profiles. The drive relies on DSF encoder feedback for precise rotor angle reporting and uses a heat-dissipation cooling method that transfers waste heat to a panel-mounted heat sink. Its open-frame IP10 construction is intended for installation inside a protected electrical cabinet. This arrangement supports responsive servo regulation in machines that require accurate speed and position control during repeated motion cycles. The closed-loop design continuously corrects motor output as feedback changes, helping the axis track commanded motion with minimal deviation.

It accepts a three-phase mains supply of 3 x 230 V AC and rectifies it to an internal DC bus stabilized at 300 V. The pulse-width-modulated output is generated at 4 kHz, allowing smooth torque production in medium-inertia motors and steady current control across changing load conditions. During continuous operation, the inverter can deliver a rated phase current of 100 A, while the upstream service transformer must be sized for a maximum apparent power of 11 kVA. The incoming line current peaks at 28 A, and overall power loss is 480 W, so the cabinet must provide enough heat removal for reliable operation.

Dynamic energy created during rapid deceleration is routed to an integrated bleeder that can dissipate up to 18 kW in short bursts and maintain 0.5 kW under steady conditions. For process signaling, the control board sources 4 mA on its analog output, providing a simple load or speed reference to external monitors. The housing weighs 11 kg, and noise emission is classified as standard for this drive type. Safe continuous service requires ambient air not exceeding 55 °C and installation below 1000 m elevation to avoid derating. These operating limits should be observed when the drive is mounted in a cabinet with other heat-producing equipment.
