Product Description:

The Bosch Rexroth Indramat DDC01.1-K150A-DA02-00 belongs to the DDC Digital Intelligent Servo Drives series. This servo drive converts three-phase mains power into controlled armature voltage and current so a connected AC motor can deliver precise torque and speed in automated machines. It integrates power electronics, signal processing, and drive protection in one IP-rated housing, giving machine builders a compact axis controller that manages acceleration, positioning, and brake control without external relay logic.

The drive accepts a nominal three-phase supply of 230 V AC and delivers a continuous output of 150 A to the motor windings. An internal comparator trips at 1.5 times the rated current to protect the power semiconductors during stalled or heavily loaded starts, while a separate DC bus monitor disconnects the inverter if bus voltage rises to 475 V. Thermal monitoring issues a warning 30 seconds before the heat limit is reached, allowing the controller to reduce load or shut down in time. At this rating, acoustic emission is classified as standard for the 100 A to 200 A range, and the housing has an IP65 rating that protects live parts from dust ingress and water jets on the machine floor.

Heat is removed by natural convection air cooling, eliminating the need for an auxiliary fan. The overall height is 775 mm when measured with the optional blower cover installed. The command module uses an analog interface, so speed and torque setpoints arrive as ±10 V signals. Rotor position is returned through digital servo feedback for closed-loop accuracy. A 24 V DC control rail powers the release coil of the holding brake, and during stopping the brake engages once motor speed falls to 10 rpm and reaches full clamping force within 400 ms. The drive uses function code 02 and is Series 1, Version 1.
