Product Description:
The 1070079652-109 servo drive module is built by Bosch Rexroth Indramat for the DMA Servo Drive Modules series. It operates as the power and control stage between a supply unit and synchronous or induction servo motors, adjusting motor torque and speed for automated machinery and material-handling lines. Its design fits into a shared backplane so that multiple axes can be handled within a single cabinet while the module supplies regulated DC energy and high-frequency switching to connected drives.
At the logic level the drive draws 1.35 A from a 24 V auxiliary supply, providing internal control power without affecting the main bus. The high-energy side is based on a regulated 670 VDC link that feeds the output bridges. Under four-kilohertz current control the continuous output is 47 Arms, while the overload channel tolerates up to 86 Arms for rapid acceleration events. Pulse-width modulation is carried out at a 8 kHz switching rate, limiting motor ripple and acoustic noise. These electrical limits determine the thermal profile, the size of the cabling, and the rating of upstream protective devices.
Heat produced during operation is capped at 380 W, evacuated by ambient air that passes through 2 integrated fans; the dual-fan array maintains component temperatures inside cabinet limits. The housing spans 100 mm on the backplane and attaches with the RMB/DM rail, following the Backplane Mechanics mounting style. Current availability decreases by 1.25 A/K between 45 °C and 55 °C, so applications in warmer enclosures must account for this derating. System integration is handled through a CAN Bus (CANrho) network, 24 V control signal terminals, and dedicated gear-encoder and 12-bit resolver channels; these interfaces form the standard variant of the module and allow direct feedback from linked axes while air cooling prevents dust buildup.
