Product Description:

The 1070080954-205 servo drive is manufactured by Bosch Rexroth Indramat as part of the DM Servo Drives series. Integrated into an industrial motion loop, it converts SERCOS fiber-optic commands into regulated phase currents for synchronous or asynchronous motors, providing the torque, speed, and position control demanded by handling robots, packaging lines, and machining centers. The unit is intended for coordinated axis control where rapid command response and stable feedback processing are required during continuous machine operation. Because it works within a closed motion loop, the drive can coordinate commanded movement with incoming feedback data instead of acting only as a power stage.

This air-cooled module operates from a DC link regulated at 670 VDC, or 715 VDC when non-regulated, and it can deliver up to 11 Arms per phase at an 8 kHz current loop. Its execute input channel accepts pulse edges up to 50 kHz, the incremental encoder interface tolerates frequencies up to 1 MHz, and a dedicated sin/cos channel is rated for 800 kHz. Continuous current is 7.4 Arms, with a thermal derating of 0.23 A for every kelvin rise in ambient temperature. The internal control electronics draw 0.89 A from the 24 V service supply, and airflow across the heat sink helps maintain semiconductor temperature in the compact housing. Rated current monitoring also supports stable operation during continuous duty.

Panel integration is eased by a mass of 6.0 kg and a housing width of 50 mm, allowing multiple axes to be mounted side by side without using excessive cabinet space. Internal conduction paths limit total power loss to 121 W, which matches the drive's forced-air cooling arrangement. Position feedback is processed with a multi-turn resolution of 32 bits and a single-turn granularity of 20 bits, supporting fine positional alignment in multi-axis gantries. As ambient temperature rises, current derating reduces output to limit thermal stress, and the slim enclosure leaves clearance for ducting and service access in confined cabinets.
