Product Description:
The CSH01.1C-PB-ENS-EN2-MA1-S1-S-NN-FW is a compact control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Integrated into IndraDrive modular drive stacks, it coordinates axis motion, local I/O, and fieldbus traffic for machinery and material-handling cells. The unit serves as the intelligence layer, translating PLC commands into torque and position targets and returning status data to higher-level automation systems. Because it is a control section rather than a power stage, it focuses on command processing, feedback handling, and coordination between the drive and the machine controller.
The control core provides 11 discrete input channels and 4 transistor outputs on the base board, allowing direct connection of limit switches, interlocks, and drive-ready signals without extra interface modules. Communication with external controllers is handled through PROFIBUS-DP, and the onboard ASIC sustains deterministic cyclic data exchange at up to 12 MBaud, so motion setpoints and diagnostic words arrive within the required bus cycle time. This arrangement lets the drive react to machine-state signals locally instead of routing every condition through a separate remote I/O node. For safety functions, the S1 hardware option adds Safety Technology I/O, enabling STO and safe door monitoring circuits to be wired directly into the section. These local safety connections can shorten the response path during emergency stop events.
The module also supplies two dedicated encoder interfaces so it can work with different motor feedback formats on the same platform. The En2 port delivers up to 350 mA and accepts EnDat 2.1/1 Vpp/5 V TTL feedback, while the Ens port can source 500 mA for IndraDyn, HIPERFACE, or 1 Vpp signals. This combination supports mixed feedback technologies without requiring a separate feedback converter for each axis. Motion tuning values reach the controller through two differential analog inputs, and two analog outputs retransmit calculated setpoints. Both directions share a programmable range of ±10 V and use 12-bit conversion for smooth velocity and torque loops.
