Product Description:
The CSH01.1C-PB-EN1-EN2-MEM-L1-S-NN-FW is a control section produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It is installed in modular drive stacks to process motion commands, handle feedback, and coordinate axis safety functions inside automated machinery. By combining fieldbus communication, encoder interfaces, and onboard safety logic, the unit links servo inverters with higher-level PLCs, enabling deterministic control of speed, position, and torque in assembly lines, packaging equipment, and material-handling cells. This arrangement allows one module to manage command processing, sensor evaluation, and safety-related shutdown behavior in compact multi-axis cabinet layouts.
The module draws a base power of 7.5 W, keeping cabinet thermal load low during continuous operation. Control communication to the master PLC is handled through the PROFIBUS-DP interface, and telegrams can be exchanged at up to 12 MBaud for time-critical motion profiles. For encoder simulation to external counters or drives, the emulation port can deliver square-wave or sin/cos signals at an output frequency of 1 MHz in either absolute or incremental format. The secondary feedback port, labeled EN2, supports EnDat 2.1, 1 Vpp, or 5 V TTL transducers and allows sense-line cable runs up to 75 m. It powers these sensors with 5.0 VDC and provides up to 350 mA, which helps maintain stable operation for connected absolute encoders.
The primary feedback channel accepts a resolver or high-speed HSF encoder, supplying 250 mA at 8 VDC to the sensor coils. When a resolver is connected, the board excites it with 18.2 Vpp at a carrier frequency of 4 kHz, supporting stable angle conversion under vibration. For safe torque-off wiring, a D-Sub 9-pin female connector is provided, and the integrated starting lockout follows the requirements of Stop Category 0, so power is removed immediately during a safety event. This combination supports direct integration of conventional resolver feedback, high-speed digital sensing, and hardwired safety inputs in multi-drive installations.
