Product Description:

The CSH01.1C-PB-EN2-NNN-MEM-S1-S-NN-FW is a single-axis control section from the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. It plugs into IndraDrive power sections and executes real-time motion tasks for servo axes in automated machinery. Acting as the local intelligence, the unit processes encoder feedback, exchanges status data with higher-level PLCs, and governs safety inputs and outputs so the drive complies with machine-level functional safety requirements.

This controller draws only 7.5 W at its base operating state, a low internal load that simplifies cabinet cooling calculations. Fieldbus communication is handled by a dedicated PROFIBUS-DP interface, giving the drive cyclic process data exchange with masters operating at up to 12 Mbit/s. When power is first applied, the electronics experience an inrush of 4 A, and that surge lasts a maximum of 100 ms, so upstream fusing and supply sizing must tolerate the brief pulse. The board supports EnDat 2.1, 1 Vpp, and 5 V TTL encoder interfaces and delivers a 5.0 V supply voltage at up to 350 mA for position transducers. Safety channels accept 24 V signals at 3 mA and source 24 V outputs rated for 0.5 A.

For axis simulation and diagnostic tools, the unit outputs emulation signals that reproduce both absolute and incremental formats. These differential channels can be carried up to 40 m without signal conditioners and operate at a maximum frequency of 1 MHz, allowing high-resolution feedback replication for downstream devices. The incremental tracks drive loads down to 35 ohms, and the shared safety supply rail can provide 1.6 A to multiple connected modules. When the drive's safe torque off logic disengages the power stage, the dedicated safety output can still provide status confirmation for external relays and other connected actuators.
