Product Description:
The DDC01.1-K150A-DG01-00 belongs to the DDC Digital Intelligent Servo Drives series from Bosch Rexroth Indramat. It is a closed-loop power stage that interfaces with synchronous motors and motion controllers in automated machinery. By combining power electronics with digital regulation, the drive converts a DC bus into controlled three-phase output and reads position data through a dedicated serial link, enabling precise velocity and torque control for axes in packaging lines, material handling cells, and similar industrial equipment.
The drive supplies a continuous output of 150 A, which is the maximum motor phase current it can deliver without derating. Its command interface offers an analog reference range of ±10 V, letting PLCs issue proportional speed or torque requests. Internal logic circuits are powered from an external 24 V DC source, which keeps the control electronics active during main power disruptions for safe shutdown routines. Protection on the high-voltage bus is triggered at 475 V, disconnecting the stage before link components exceed their insulation limits. Gate pulses to the power transistors require a minimum width of 100 ms, which helps prevent chattering during fault resets or enable commands. Natural convection air cooling disperses switching losses, and digital servo feedback carried over a 75 m shielded line maintains position accuracy even when the motor is mounted far from the cabinet.
The DC link becomes operational once the capacitor bank reaches 200 V, a threshold that prevents control activation on an undervoltage bus. An overcurrent alarm is issued when phase demand rises to 1.5 × rated current, giving the controller time to decelerate the axis before a hard trip. The sealed aluminum housing meets IP65, so it resists coolant splash and airborne dust on the machine frame. Operation is permitted at installation heights up to 1000 m. The drive is also rated for 95% relative humidity, uses function code 01, and falls within the standard acoustical class for 100 A to 200 A devices.
