The 1070070780 (DMA 85B 1101-D) servo drive module, courtesy of Bosch Rexroth Indramat, forms part of their esteemed Servodyn D series. The module pairs excellently with both asynchronous and synchronous motors, irrespective of the manufacturer. This three-phase unit is equipped with position control and leverages air cooling through its backplane. It has a compact design, allowing it to fit into a control cabinet with a depth of 300mm. After disconnection, the unit should be left for at least five minutes for dissipation of residual charge before removing the cover. Adherence to measures for ESD protection is crucial for safe operation. It is 50mm wide. This standard servo drive module hosts a generous feature set, including the SERCOS interface that promises realtime processing and simple installation and commissioning processes. Its 32-bit signal processor supports digital control of current, speed, and position. Its distinctive personality module brings forth a 2-channel redundant safety monitoring via RSU capability. Operating on a modest 1.35A demand from a 24V power supply unit, it also possesses a precise 12-bit resolver for position value. Users must heed warning signs to avoid personal injury and damage to the module components. Its backplane module facilitates two fans and can handle currents up to 86ARMS at 4kHz frequency and a regulated DC link voltage of 675VDC. It experiences a derating between 45°C and 55°C.
