Product Description:

The DDC01.1-K150A-DL10-01-FW is a digital intelligent servo drive manufactured by Bosch Rexroth Indramat within the DDC Digital Intelligent Servo Drives series. The unit interfaces with motors and machine controllers to regulate speed, torque, and position in automated production cells. Its single-axis design combines power conversion and motion control in one housing, reducing the need for separate cabinet-mounted assemblies. The sealed enclosure supports cabinet-free mounting on machinery where space around the axis is limited.

Electrical capacity starts with a rated output current of 150 A, allowing the drive to handle demanding acceleration and deceleration cycles from a compatible digital servo feedback loop. Line-side demand reaches 22.5 kVA at full rating, and internal conversion produces a continuous mechanical output of 15 kW so the unit can sustain substantial motor output during operation. Short duty bursts can rise to 25 kW, giving added headroom during brief peak loads. During braking, the integral bleeder circuit dissipates 1.0 kW of heat continuously to maintain DC-bus stability. Natural convection through the aluminum housing provides cooling without forced-air components. Under nominal operation, the device rejects 540 W of power loss, and its 22 kg mass supports stable mounting on the machine frame.

The bleeder can absorb momentary surges up to 40 kW and capture a maximum of 10 kWs of regenerative energy, preventing DC-bus overvoltage during rapid deceleration or frequent stopping cycles. Pulse-width modulation is executed at 4 kHz to balance switching loss against current ripple in the motor current. The sealed enclosure carries an IP65 rating that shields live components from dust and water jets. Reliable service is maintained to 55 °C with derating, and the drive tolerates 95% relative humidity without condensation. A single-axis positioning command module manages motion, and the drive is function code version 01, series 1, and version 1.
