Product Description:

Bosch Rexroth Indramat manufactures the DDC01.2-F200A-DS01-02-FW servo drive in the DDC Digital Intelligent Servo Drives series. This unit is a digital controller that regulates induction and synchronous motors by adjusting speed and torque in closed-loop motion axes. In industrial automation, it provides coordinated positioning, rapid acceleration, and dynamic stopping for packaging lines, handling robots, and machining centers. It can also support applications that need repeatable motion and stable response during changing load conditions.

At the power stage, the drive can supply up to 200 A of continuous output current, enough for large motors that demand high starting torque. Internally, the IGBT bridge is modulated at 4 kHz, a pulse frequency that balances switching losses with smooth current resolution. A liquid cooling circuit removes generated heat and helps keep semiconductor temperature stable during sustained operation. The housing maintains an IP65 ingress rating so the unit can be mounted directly on the machine frame without a cabinet. Incoming mains capacity of 22.5 kVA is required to feed the converter and its auxiliary electronics, and the unit has an overall mass of 22 kg. Direct machine mounting can also help simplify enclosure layout in systems that place the drive close to the axis.

Energy recovered during deceleration is routed to an integrated bleeder. Under continuous braking, the resistor dissipates 0.25 kW, and it tolerates peaks of 40 kW for short intervals to prevent DC-bus overvoltage. If the load produces extended regeneration, the power section can absorb up to 20 kWs before thermal limits are reached. During steady-state operation, the converter's own losses are 500 W, a value that should be considered in enclosure heat calculations. Motor position is tracked through digital servo feedback, and the command module uses a SERCOS interface for deterministic communication with higher-level motion control. This arrangement supports coordinated multi-axis operation where accurate feedback and predictable command timing are required.
