Product Description:
The CSH01.1C-SE-EN2-ENS-MA1-S1-S-NN-FW is a single-axis control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in IndraDrive modular drives, it coordinates motion commands, gathers feedback from multiple encoder formats, and exchanges data with higher-level PLCs through the SERCOS interface. By combining embedded safety inputs and integrated analog I/O, the unit directs servo performance, sequencing, and diagnostic reporting inside industrial automation cells. This arrangement allows one module to manage command processing, feedback evaluation, and operating status for a complete servo axis.
The base board presents a differential analog front end with an input resistance of 160 kΩ, which limits loading on connected sensors. Its two analog outputs can source up to 1 mA each and can swing to 5 V, providing scaled command signals to external actuators. The EN2 option supplies incremental encoders with a regulated 120 Ω termination and delivers a supply current of 350 mA at 5 V DC to power optical or magnetic read heads. Two additional analog inputs and two analog outputs are routed through the MA1 mezzanine, and all four channels use 12-bit resolution for precise signal handling during closed-loop operation. The control section also passes command and measurement data to the paired inverter within the modular drive assembly.
When the ENS interface is selected, the controller distributes 12 V DC to absolute encoders such as IndraDyn or Hiperface while providing up to 500 mA of current for heater-equipped feedback lines. The quadrature input path on this channel accepts signal frequencies as high as 400 kHz, which helps maintain interpolation accuracy at elevated shaft speeds. Safety technology I/O is embedded on the section so certified stop and enable signals can bypass the main fieldbus. Option 1 supports EnDat 2.1, 1 Vpp, and TTL formats, while Option 2 adds IndraDyn, Hiperface, 1 Vpp, and TTL compatibility, allowing flexible feedback selection without external adapters.
