Product Description:

The CSH01.1C-SE-EN2-EN2-MD1-NN-S-NN-FW is a control section produced by Bosch Rexroth Indramat and supplied within the CSH Advanced Controllers series. Installed inside IndraDrive modular drive stacks, the unit coordinates feedback channels, SERCOS communication, and local digital I/O so that multiple servo axes can follow commanded motion accurately. By combining encoder processing with discrete machine signals, it serves as the interface between servo motors and higher-level automation equipment. It is intended for modular drive assemblies where motion control, feedback evaluation, and machine-level signal exchange must remain in one compact section.

The housing is compact, with a width of 49.5 mm, a height of 241 mm, and a depth of 103 mm. Internally, 2 encoder interfaces are available, and each channel accepts sensors that use EnDat 2.1, 1 Vpp, or TTL signaling. Upstream communication relies on an optical SERCOS ring with data exchange rates of up to 16 MBaud. The encoder channels let the drive process position and velocity information directly, which supports accurate loop closure at the axis level. This also allows fast transfer of position values and diagnostics while preserving short control-cycle timing for coordinated motion.

Discrete machine signals are handled through the MD1 terminal block, which offers 12 digital inputs for limit switches, sensors, or probes and 8 digital outputs for relays, indicator devices, or brake control. The secondary encoder connector processes incremental or absolute feedback at rates of up to 1000 kHz. Its sensor supply provides a regulated 5 VDC source, which lets compatible encoders receive power directly from the control section. Each MD1 output can source 0.5 A, which is suitable for small actuators and status signaling devices. Because the I/O and encoder supply are integrated, external interface hardware can be reduced in cabinets that use distributed sensors and standard encoder wiring.
