Product Description:

The CSH01.1C-ET-EN2-NNN-MA1-L2-S-NN-FW is a modular control section supplied by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It plugs into an IndraDrive power module and provides coordinated motion processing, network bridging, and integrated safety for multi-axis machinery. By combining real-time Ethernet interfaces, encoder evaluation, and analog process channels on one board, the unit streamlines cabinet layout and supports central or distributed automation schemes in packaging, handling, and forming lines.

The controller’s base electronics require 7.5 W, while the ET and EN2 option cards add 2.2 W and 6 W respectively, so panel heat dissipation can be calculated for closed enclosures. Multi-Ethernet capability is carried on a single port that follows the 100Base-TX standard, enabling SERCOS III, EtherNet/IP, or PROFINET traffic without hardware changes. During power-up the section can draw an inrush of 4 A, which should be considered for fuse sizing and supply bus buffering. Two analog acquisition channels are present; they accept two differential voltage inputs digitized with 12-bit resolution, allowing precise monitoring of load cells, tension sensors, or external feedback devices. A separate 2 W allocation covers the MA1 mezzanine so that additional analog functions do not overload the primary backplane budget.

For command tasks, the MA1 channel provides two voltage outputs rated at 10 mA source current and stable with loads down to 1 kΩ, making them suitable for valve drivers or transducer references. Encoder connections support EnDat 2.1, 1 Vpp, and 5 V TTL formats; the onboard supply presents a regulated 5 V feed to the measuring head, eliminating external power taps. Functional safety is addressed by the integrated Safe Torque Off, which removes drive energy through hardware logic instead of software commands.
