Product Description:
The CSH01.1C-ET-ENS-MEM-MA1-L2-S-NN-FW is a single-axis control module manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive cabinet, it translates fieldbus data, encoder feedback, and local analog signals into velocity and position commands. This allows coordinated motion sequences and integrated machine safety within industrial automation cells.
This module samples each analog channel with a resolution of 12-bit, so process variables are digitized into 4096 discrete steps. Both its input and output stages accept a linear range of ±10 V, making the board compatible with standard servo reference levels. Network connectivity is handled by the Multi-Ethernet interface, which supports PROFINET, EtherNet/IP, or EtherCAT. The port terminates on an RJ-45, 8-pin jack and supports cable runs up to 100 m using the 100Base-TX standard. Encoder simulation is delivered through an emulation driver that produces square-wave or sin-cos tracks at a ceiling of 1 MHz, while the TTL capture path accepts marker or incremental streams up to 400 kHz. A 40 m emulation cable length allows remote feedback devices to be mounted outside the drive enclosure without signal degradation.
The differential encoder input presents a 120 ohm termination to match twisted-pair impedance and reduce reflections. Its sensor rail supplies 11.6 V DC at up to 500 mA, powering external absolute or incremental transducers directly from the board. Safe motion is enforced through the Safe Torque Off function, which is activated by a dedicated D-Sub 9-pin female safety connector; once it is asserted, the drive’s gate signals are removed without relying on downstream relays. These signal interfaces allow the controller to work with both absolute and incremental feedback devices on the same drive platform.
