Product Description:

The CSH01.1C-SE-ENS-NNN-MEM-NN-S-XP-FW controller belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. This unit provides closed-loop axis supervision for servo drives, allowing a single axis to handle tasks such as indexing tables, packaging axes, or feed rolls. By combining a SERCOS II master channel with multiple encoder interfaces, it links motion commands to deterministic bus cycles used in factory automation.

Its analog reference circuit has an input resistance of 160 kOhm, so external sources experience minimal loading when driving position or velocity setpoints. The unit provides up to 2 programmable analog voltage outputs for drive-based diagnostics or process signals. The primary encoder socket supports IndraDyn, HIPERFACE, 1 Vpp, EnDat 2.1, or TTL formats, while a MEM port supplies simulated encoder data with an output frequency ceiling of 1 MHz. Up to 500 mA of sensor supply current is available to power external transducers. A startup inrush current of 4 A must be considered when sizing cabinet fusing. The controller can generate individual pulse trains as wide as 100 ms, enabling drive-based probing or latch functions without external timers. Axis selection, encoder emulation mode, and SERCOS II telegram structure are set through the RS232 service port.

The housing measures 241 mm in height and 49.5 mm in width, allowing dense stacking alongside IndraDrive power modules. Its depth is 103 mm, which helps the unit fit compact control cabinets without wasting panel space. Encoder emulation signals can travel up to 40 m over shielded MEM cabling without loss of integrity, which supports remote feedback distribution to downstream devices. An 8-pin MiniDIN connector carries the RS232 interface for service access and parameter backup. When configured as a single-axis card, the controller reserves dedicated logic for torque, speed, or position loops, so no additional daughter boards are required.
