Product Description:

The DDC01.2-N200A-DL41-01-FW is a digital intelligent servo drive manufactured by Bosch Rexroth Indramat for the DDC Digital Intelligent Servo Drives series. It combines a power stage, a single-axis positioning command module, and regenerative circuitry in one enclosure. The device connects directly to compatible Indramat synchronous motors and reads feedback from an integrated digital encoder, allowing precise torque, speed, and position control without a separate external motion processor. In automated assembly lines, packaging stations, and material-handling gantries, it functions as the main interface between PLC motion commands and the driven axis. Its integrated layout keeps control and power functions in the same housing during operation.

The internal bleeder circuit dissipates regenerative energy continuously at 0.25 kW, while short bursts up to 40 kW are absorbed during rapid deceleration or vertical-axis movement. In normal duty, the unit delivers 200 A of controlled motor current, and the incoming supply must be sized for a maximum demand of 22.5 kVA. Power transistors switch at 4 kHz, which balances current smoothness with audible noise. Even when the axis is stationary, the electronics release 500 W of heat, so the mounting location must allow steady heat removal during continuous operation. This arrangement supports repeated braking events produced by dynamic servo motion.

Standard cooling relies on ambient airflow, so the installation site must remain below 55 °C and within the stated altitude limit. The cast-aluminum housing is sealed to IP65, which keeps out dust and resists water jets, allowing the unit to be mounted on the machine rather than only inside a cabinet. With the power module, command card, and bleeder resistor installed, the unit weighs 22 kg, so the supporting structure must be rigid enough for machine-mounted service. A relative humidity limit of 95 percent requires non-condensing conditions. This layout is useful where cabinet space is limited and the drive must sit near the motor.
