Product Description:

Bosch Rexroth Indramat’s CSH01.1C-PL-EN2-NNN-MEM-L1-S-NN-FW is a plug-in control unit belonging to the CSH Advanced Controllers series. Fitted to IndraDrive power sections, the board generates motion profiles, handles encoder feedback, and coordinates multi-axis sequences during automated assembly, packaging, or printing tasks. By embedding closed-loop algorithms close to the drive electronics, the card reduces response latency and allows the host PLC to offload time-critical interpolation for precise position and speed control across the machine.

Within the rack, the module exchanges command words through a Parallel Interface, while sixteen inputs capture tool states and sixteen outputs return status bits. A dedicated acknowledgment driver sources 24 V / 1 A for contactors, and the analog monitor delivers 5 V / 1 mA for reference tracking. Discrete signaling is reinforced by a transistor stage rated at 24 V / 0.5 A to power relay coils or indicators. The card provides an encoder port for EnDat 2.1, 1 Vpp, and 5 V TTL signals, supplied from an internal 5 V rail, so it can accept absolute and incremental sensors without external conditioning. A starting-lockout terminal evaluates 24 V at 3 mA before permitting drive enable. Encoder emulation signals can be retransmitted over 40 m of shielded cable without timing degradation.

The emulation stage reproduces differential step-direction tracks with an output of 1 MHz, driven at 20 mA so downstream drives receive clean square edges for phase-locked speed tests. Cable management is application-dependent: installations that implement sense conductors may span up to 75 m, whereas unsensed runs must not exceed 50 m to maintain voltage stability. These distance limits, combined with encoder emulation that mirrors both absolute and incremental formats, let the controller synchronize auxiliary axes and perform setup procedures without a motor connected.
