Product Description:

The CSH01.1C-NN-EN2-EN2-NNN-L1-S-NN-FW is a control section distributed by Bosch Rexroth Indramat for use in the CSH Advanced Controllers series. Installed in an IndraDrive power unit, the module acts as the processing core that interprets feedback, issues motion commands, and manages safety signals for multi-axis automation lines. By combining encoder feedback channels, analog scaling, and discrete I/O on one card, it streamlines servo regulation tasks within packaging, printing, and material-handling equipment. It is intended for applications that require coordinated motion, signal exchange, and integrated drive supervision in a compact control platform.

The controller accepts differential analog position or torque references through an input impedance of 160 kΩ, which helps minimize loading on upstream transducers. It provides 2 analog outputs rated at 5 V and 1 mA for drive-level scaling or external monitoring. Switching signals enter through digital inputs rated at 24 V, 3 mA, while machine status bits are sent through digital outputs rated at 24 V, 0.5 A. Two encoder ports support 2 x EnDat 2.1 / 1 Vpp / TTL formats, allowing the section to process feedback from both rotary and linear sensors. During power-up, the section can draw an inrush current of 4 A, which should be considered when sizing cabinet protection devices.

Baseline consumption under idle logic load is 7.5 W, an important value for thermal planning in densely packed enclosures. Safety is handled by a starting lockout function that inhibits torque generation until the enable sequence is satisfied. The unit has a compact mechanical layout with a depth of 103 mm, a width of 49.5 mm, and a height of 241 mm. A relay contact rated at 24 VDC and 1 A supports direct interlocking to motor contactors, and the maximum output pulse width is 100 ms for deterministic handshaking with downstream drives.
