Product Description:

The CSH01.1C-PL-EN1-EN2-MEM-NN-S-NN-FW is an advanced controller card produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It plugs into IndraDrive modular drives and coordinates servo axes, sensor feedback, and field-level signals inside automated machinery. By handling position loops, converting encoder data, and routing discrete I/O, the card forms the real-time link between the drive’s power section and higher-level motion programs used in conveyors, pick-and-place gantries, and other factory automation equipment.

Base power consumption is rated at 7.5 W, so the control rack can allocate minimal standby power for each card. Command exchange with the drive occurs through a Parallel Interface, which supports deterministic signal timing. The first encoder channel, EN1, accepts Resolver/HSF feedback and provides up to 250 mA from an auxiliary supply of 8 V DC for transducer excitation. When memory emulation is active, the integrated line driver can support a cable length of 40 m without repeaters. Typical startup draw is 4 A, and a 100 ms inrush pulse profile helps protect upstream fuses while capacitors charge. The absolute position format follows SSI, allowing bit-serial transfer of multi-turn data.

The second encoder channel supports EnDat 2.1, 1 Vpp, or 5 V TTL signals and is designed for feedback lines up to 75 m. It powers the transducer with 5.0 V DC at a continuous 350 mA source limit, enabling high-resolution sine-cosine encoders. For rapid nonvolatile storage, the MEM port streams absolute or incremental data at a clock rate of 1 MHz. Discrete machine states are wired directly to the board through 16 DI / 16 DO, eliminating the need for separate I/O modules. The I/O and memory functions support direct sensor acquisition, actuator control, and retained position data during power interruptions.
