Product Description:

The DDS02.1-W100-RL04-01-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. Designed to regulate torque, speed, and position in single-axis automation, this unit acts as the power and control stage between the supply module and an Indramat servo motor. In automated assembly lines or material handling cells, it issues precisely timed current pulses so the connected motor can execute repeatable linear or rotary movements with stable response during acceleration, deceleration, and dwell periods. This arrangement lets the drive convert control commands into regulated motor current while maintaining the closed-loop behavior needed for accurate axis motion.

The controller delivers a continuous output of 100 A, which is the maximum RMS phase current it can supply to the motor windings under standard thermal conditions. Air from inside the control cabinet passes across its heat sink, so the cabinet’s internal airflow must be sufficient to remove waste heat. Motion commands are processed through the single-axis position control interface, letting the unit position one axis without a central motion coordinator. To close the loop, it accepts resolver feedback for shaft angle feedback during operation. The electronics have an IP20 protection category, so cabinet mounting is required to shield the unit from direct contact and airborne debris.

Installation limits affect cabinet layout and operating conditions. An altitude of up to 1000 m above sea level is permitted before derating is required. The unit operates continuously between 0 to 45 °C, and storage is allowed from -30 to 85 °C for transport or warehouse staging. The controller is intended for enclosed industrial panels in standard machine-room conditions, and the product is part of Line 02 with hardware version 1.
