Product Description:
The CSH01.1C-PL-EN1-MEM-MA1-NN-S-NN-FW is a plug-in control section produced by Bosch Rexroth Indramat for integration into drive stacks that use the CSH Advanced Controllers series. It supplies axis-specific processing, I/O handling, and feedback evaluation so that an IndraDrive power module can execute precise motion sequences in industrial automation cells. By combining encoder evaluation, analog command inputs, and high-speed memory emulation on one board, the device coordinates servo positioning tasks that require deterministic timing between the master control system and the individual motor channel.
Its output circuitry offers a digital channel block rated at 24 V, 0.5 A, allowing direct actuation of relays or indicators without external drivers. The module occupies a compact slot area of 241 × 49.5 × 103 mm, so multiple axes can be lined up inside a control cabinet with minimal spacing. Command data from the central PLC reaches the section through a Parallel Interface, which minimizes protocol overhead and keeps update latency low. Process variables enter the drive through two differential inputs that accept ±10 V signals. Each incoming sample is digitized with 12 bit resolution, balancing conversion speed with enough granularity for velocity or torque loops.
The EN1 feedback channel evaluates resolver and high-speed sine-frequency transducers. It excites the resolver at 18.2 Vpp and senses return signals at 4 kHz, allowing the drive to calculate absolute rotor position even during rapid acceleration. For legacy CNC systems, the MEM output can emulate both absolute and incremental encoders, and its differential line drivers maintain signal integrity along cables up to 40 m. With a ceiling of 1 MHz for incremental pulse generation, the section can support finely gridded positioning tables without overloading downstream counting electronics.
