Product Description:

The CSH01.1C-PB-ENS-MEM-MD2-S1-S-NN-FW is a plug-in motion controller module produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in Rexroth drive cabinets, this unit combines fieldbus communication, encoder handling, and digital I/O so the drive can synchronize with higher-level PLCs and peripheral sensors. Within an automation line the module processes position data, forwards it to the power section, and transmits status to the plant network, allowing coordinated axis control without separate stand-alone gateways.

In the communication layer the module supports PROFIBUS-DP, giving deterministic cyclic exchanges with the master controller. Encoder feedback from the ENS channel is digitized at 12 bit resolution, so each analog cycle is broken into 4096 discrete steps for fine position tracking. The same channel passes signals through an antialias filter set at 500 kHz, which prevents high-frequency noise from folding into the sampled spectrum. A dedicated supply of 11.6 V is available for external encoders, eliminating the need for an auxiliary power rail, and the input circuitry presents 120 ohm of impedance to match standard differential transmission lines. Together these characteristics allow precise motion data to enter the controller with minimal distortion.

For machine level interaction the MD2 block provides 16 digital inputs and an equal number of outputs; each output can switch loads up to 24 V / 0.5 A so valves, relays, or lamp stacks can be driven directly. High-speed sensor buses connect to the MEM interface, which maintains signal integrity over cables as long as 40 m while toggling at an internal strobe rate of 1 MHz. Upstream, the PROFIBUS connector is a female D-Sub and reaches network rates of 12 MBaud, ensuring the axis data produced by the controller reaches the PLC within one scan. These hardware resources keep the drive, sensors, and fieldbus aligned without additional interface cards.
