Product Description:

The CSH01.1C-ET-NNN-NNN-NNN-L2-S-NN-FW is a modular controller card produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive assembly, this card processes motion commands, supervises feedback, and links the drive to higher-level PLC or HMI networks. It supports coordinated axis control in automated machinery and keeps command handling, feedback monitoring, and network communication in one drive-mounted control platform.

The communication backbone is Multi-Ethernet, allowing protocol selection while maintaining the electrical layer of 100Base-TX. Field wiring follows the CAT5e performance class, and an integrated ITP shield helps keep high-frequency noise from coupling into the data pairs. Two differential analog channels accept signals through an input resistance of 160 kΩ, which minimizes loading on external sensors, and the corresponding voltage outputs resolve increments of 19.5 mV/Inc for drive-level reference commands. Eight sourcing digital outputs are rated for 0.5 A per point, which provides enough current to operate contactors or indicator lamps without auxiliary relays. Optional slots 1 to 3 are empty on this variant, so expansion with additional encoder interfaces or fieldbus masters is not available.

Safety and timing parameters complement the card’s control and communication functions. The integrated Safe Torque Off channel disconnects gate-drive power through a dedicated D-Sub 9-pin female STO connector, removing motor torque without using the main contactor loop. Encoder validation tasks can be synchronized by a probe input that captures transitions with a pulse width down to 4 µs. Network cables may extend up to 100 m before a repeater is required, allowing the controller to be installed at the far end of a machine cell. For status reporting, a single-line standard panel shows drive-state codes, and maintenance contacts are provided through a relay rated at DC 24 V 1 A so external alarms can mirror internal fault conditions.
