Product Description:

The CSH01.1C-NN-ENS-NNN-MEM-L2-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted beside power inverters, it performs interpolation, encoder evaluation, and Safe Torque Off supervision so that connected servo axes follow commanded profiles while a discrete safety line is maintained. The card slides into a narrow slot and connects to feedback devices through its front panel, making it suitable for conveyors, pick-and-place axes, and gantry drives.

During operation, the module dissipates a base load of 7.5 W, a figure used for enclosure heat calculations. Its analog inputs are digitized with a 12-bit resolution, giving adequate position granularity for most servo loops. Control electronics are fed from a stabilized rail at DC 24 V. When this rail is first applied, the board draws an inrush of 4 A lasting roughly 100 ms, so fuses and supply cables must tolerate that short surge. After the pulse, input current drops to normal levels, allowing the section to share a common control bus with other drive electronics without oversizing the power supply.

Additional signal resources extend the card’s application range. The encoder port provides 500 mA at 11.6 V, enough to power most SinCos, EnDat, or Hiperface transducers directly. For virtual master functions, an emulation channel outputs square waves up to 1 MHz over a 40 m cable, supporting phase-locked follower axes. A fast latch input accepts TTL edges at up to 400 kHz, enabling precise capture of registration marks on high-speed packaging lines. Absolute position data can also be shifted via an SSI link that drives differential pairs in the RS-422 format, helping maintain signal integrity across long machine runs while fitting within the 241 mm height, 49.5 mm width, and 103 mm depth of the module.
