Product Description:

The 1070080960-207 is a servo drive module manufactured by Bosch Rexroth Indramat within the DMA Servo Drive Modules series. Installed in a control cabinet, the unit converts stored DC bus energy into regulated three-phase output so that connected motors follow commanded torque, speed, or position profiles in automated assembly lines, pick-and-place cells, and material-handling stations. It works in conjunction with Indramat controllers and feedback devices to close the motion loop and supply the high-frequency switching required for precise axis regulation.

On the control side, the drive draws 1.32 A from the 24 V auxiliary supply, while the power stage can deliver up to 51 Arms for short-term overload at a 4 kHz carrier and a continuous 39 Arms at the same frequency. Heat loss is limited to 220 W, and it is removed by air cooling through the backplane and two integrated fans that force airflow across the heat sink. The housing occupies only 50 mm of rack width, supporting dense multi-axis arrangements. All current figures apply before carrier-frequency derating and assume cabinet airflow supplied by the system fan tray.

When switching frequency increases, output capability drops according to the derating curves. Each kelvin above the reference temperature reduces current by 0.65 A/K at 4 kHz and 0.45 A/K at 8 kHz, so temperature management remains important. No onboard encoder interface is provided; instead, the module relies on upstream electronics that process incremental feedback up to 1 MHz, sine signals to 50 kHz, and combined sine-cosine channels to 800 kHz. Command and diagnostic data can pass through the optional PROFIBUS-DP link, with position words carried as 20-bit single-turn values or 32-bit multi-turn data spanning 4096 revolutions. A manual-mode variant supports operation at lower DC bus voltage during setup.
