Product Description:

The CSH01.1C-SE-ENS-EN2-MEM-L2-S-XP-FW is an axis control section produced by Bosch Rexroth Indramat in the CSH Advanced Controllers series. Within a multi-axis IndraDrive platform, it processes motion commands and closes encoder feedback loops. It also exchanges deterministic data with upstream PLCs to coordinate servo amplifiers in automated machinery.

The controller accepts velocity or torque references through an analog channel that presents an input resistance of 160 kOhm, so the source device experiences minimal loading. When a monitored analog feedback is required, the board delivers up to 1 mA at a reference level of 5 V, providing a stable signal for external sensors or recorders. Real-time motion traffic moves over a SERCOS optical ring, and the hardware supports rates of 16 MBaud, enabling sub-millisecond cycle times. A maintenance port based on the RS232 electrical standard is terminated on an 8-pin MiniDIN female connector for setup or service. The module reads IndraDyn, Hiperface, 1 Vpp, or TTL encoders on its first feedback socket, while a second channel accepts EnDat 2.1, 1 Vpp, or TTL formats. An internal generator can create encoder-emulation pulses for legacy drives, and machine stop action is implemented with the Safe Torque Off circuit wired through a 9-pin female D-Sub connector.

The unit stands 241 mm tall, extends 103 mm deep behind the mounting rail, and occupies only 49.5 mm in width, allowing several axes to share one panel without enlarging the enclosure. The supplied serial cable can span 15 m between the controller and a diagnostic station, keeping service equipment outside guarded cells. Because the optical fiber ring resists electromagnetic interference, long motor leads do not corrupt motion commands. The dual encoder inputs also support straightforward migration from older feedback systems.
