Product Description:

The CSH01.1C-SE-EN1-ENS-EN2-S2-S-NN-FW is a control section from the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. It slides into modular drive racks and supplies the sequencing, axis coordination, and fieldbus communication required in industrial automation cells. By combining motion logic with integrated encoder evaluation, the unit functions as the command layer for servo inverters, allowing machine builders to synchronize multiple motors, manage safety functions, and link a plant-level PLC to the drive train.

The controller exchanges real-time data over the SERCOS interface while an RS232 port remains available for setup or service tasks. Two digital outputs are rated at 24 VDC and can each source up to 0.5 A, making them suitable for contactor coils or status lamps. Dedicated encoder supplies include 8 VDC for the primary resolver channel and 5 VDC for TTL or HIPERFACE sensors, so feedback devices draw power directly from the card. Encoder 1 accepts resolver or HSF signals, and the Safe Motion option monitors these inputs to enforce velocity- and position-based shutdown without external relays.

A single-line control panel display gives local parameter access, while the additional sensor rail supplies 12 VDC to secondary feedback chains. Encoder 2 handles IndraDyn, HIPERFACE, or 1 Vpp formats, and Encoder 3 can read EnDat 2.1, 1 Vpp, or 5 V TTL signals, allowing mixed-technology feedback on the same axis group. Probe inputs capture position markers with an accuracy of 1 µs and accept pulses as short as 4 µs, permitting precise registration tasks on printing or packaging lines. For resolver channels, the card delivers an excitation of 18.2 Vpp at 4 kHz, a combination that keeps signal integrity high over long motor cables while maintaining stable angle calculation for closed-loop speed control.
