Product Description:

The DDC01.2-K050A-DA02-01-FW is a digital servo drive from Bosch Rexroth Indramat in the DDC Digital Intelligent Servo Drives series. It supplies controlled three-phase power to compatible Indramat AC motors in automated machinery. Its IP65 housing allows cabinet-free mounting close to actuators, which can shorten motor cable runs and place the power stage near the axis. An analog command module accepts velocity or torque references from a PLC or motion controller, and digital servo feedback from the motor returns position data so the drive can regulate speed, torque, and axis response in packaging lines, transfer systems, and similar equipment.

The drive delivers a continuous output current of 25 A for rated operation and a peak output of 50 A during acceleration or disturbance rejection. Excess DC-bus energy is dissipated through a bleeder rated at 0.25 kW, and that circuit can handle surges up to 10 kW during rapid deceleration. The inverter switches at a carrier frequency of 8 kHz, which helps reduce motor acoustic noise compared with lower PWM rates. Natural-convection air cooling removes generated heat, so no fan is required. The drive uses a 6 kVA mains connection, function code 02, and code version 01, while series 1 and version 2 indicate the product revision.

The controller supports a continuous shaft output of 4 kW and can reach 8.5 kW for brief load peaks, which is useful when the axis must overcome short increases in demand. A short-term load of 8 kW sits between the continuous and peak ratings, giving the axis added margin during brief duty changes. It can also absorb up to 5 kWs of regenerated energy in the DC link before external braking measures are needed. Overall power loss is limited to 500 W, supporting thermal management during sustained operation and repeated braking cycles.
