Product Description:

The DDC01.1-K100A-DC04-01-FW is a drive unit manufactured by Bosch Rexroth Indramat for the DDC Digital Intelligent Servo Drives series. It operates as the closed-loop power stage between a motion controller and an AC servo motor, translating command signals into precisely modulated three-phase output. An INTERBUS-S command module supports communication for axis control in material-handling cells, packaging equipment, and automated assembly lines. The integrated design combines power conversion and closed-loop regulation in one enclosure, which helps reduce external hardware around the machine axis.

This drive draws a rated phase current of 100 A, which supports continuous torque delivery with a compatible motor. The mains side requires 18 kVA to supply the converter, control electronics, and brake resistor. During continuous duty, the power section supports a mechanical output of 6 kW, and it can tolerate short bursts up to 17 kW during rapid acceleration. A carrier frequency of 4 kHz governs the PWM switching pattern, balancing dynamic response with motor acoustics. The housing has an IP65 rating that protects the electronics from dust and low-pressure water jets. Heat is removed through an aluminum heat sink that relies on ambient airflow rather than forced ventilation.

An internal resistor bank dissipates 0.25 kW continuously and can absorb regeneration peaks of 20 kW during high-inertia deceleration. The drive can store up to 10 kWs of energy momentarily before an overvoltage fault occurs, which helps the axis absorb brief braking events. Digital servo feedback from the motor encoder closes the velocity and position loops during operation. This feedback arrangement supports stable speed and position control when the drive is paired with a compatible AC servo motor. Standard noise emission places the unit in the 100 A to 200 A rating class, matching applications that need sealed construction and high current capacity.
