Product Description:
The CSH01.1C-S3-EN2-NNN-MA1-NN-S-NN-FW is a plug-in control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Designed for installation in IndraDrive drive stacks, the board coordinates motor axes, processes local analog signals, and exchanges real-time data over the drive bus to support machine automation. Within an IndraDrive configuration, it functions as the central motion and I/O processor, translating SERCOS commands into amplifier-level actions while forwarding feedback from encoders and sensors back to the master controller.
The control section draws a base standby demand of 7.5 W; this figure covers the CPU, memory, and network logic. Dedicated sub-assemblies are supplied separately: the analog I/O area consumes 2 W, the communication plug that hosts SERCOS cabling adds 1 W, and the encoder interface requires 6 W. Two differential analog inputs are available, each with a 1 kHz bandwidth, 12-bit conversion depth, and an input resistance of 1000 kΩ that limits loading on external transducers. Matching the inputs, the board provides two voltage-scaled analog outputs with 12-bit resolution for set-point generation or diagnostic use. Command transfer is handled through the SERCOS III real-time bus at cycle times selected by the axis controller.
Each analog output can source up to 10 mA and is designed for loads down to 1 kΩ, allowing direct linkage to drive enable circuits or external meters without amplification. The encoder connector supports EnDat 2.1, incremental 1 Vpp, or 5 V TTL formats, so a single control card can service both absolute and incremental feedback. To protect the differential receivers, the input stage is rated for a load of 35 Ω while delivering a stabilized sensor supply of 350 mA to power the attached measuring head. These limits support position control with compatible feedback devices.
