Product Description:

The CSH01.2C-PL-EN2-MEM-CCD-S1-S-NN-FW control section is produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. Intended for use in IndraDrive servo systems, this card handles axis command processing, feedback decoding, and machine-level safety tasks in a single slot. By combining drive coordination and logic evaluation, it links higher-level fieldbuses to the power stages that energize the motors. This arrangement allows one control section to manage motion responses, signal evaluation, and interlocked machine behavior within the same drive platform.

Its analog front end accepts signals within a ±10 V span, and those inputs have a high impedance of 160 kΩ, which helps reduce loading on external transducers. The board can re-transmit motion references through an analog output fixed at 5 V. Supply power is drawn from a backplane rail at DC 24 V, and the module can draw a brief inrush current during insertion. A separate EN2 port supplies regulated encoder power, while command exchange with the host PLC occurs through a parallel interface. The primary feedback channel supports EnDat 2.1, 1 Vpp, or TTL formats, allowing the control section to work with several common motor sensor types.

Digital actuator lines can deliver up to 0.5 A per channel, and timing resolution is supported by a maximum output pulse width of 100 ms. For high-speed counting or position synthesis, the MEM port operates at 1 MHz. Total board dissipation is limited to 8.5 W, which supports passive cooling inside compact cabinets where airflow may be limited. Functional safety is supported by the integrated Safety Technology I/O option, which works with a relay contact for hard-wired interlocks. The encoder emulation plug-in and the cross-communication drives module allow adjacent inverters to share position data directly, which reduces bus traffic during synchronized motion.
