Product Description:

Bosch Rexroth Indramat builds the CSH01.1C-S3-EN2-MEM-MD2-NN-S-NN-FW as a plug-in control section for the IndraDrive platform within the CSH Advanced Controllers series. The card provides axis logic, fieldbus communication, and encoder processing, so it serves as the central coordinator between power electronics and higher-level automation systems. By combining motion control, I/O handling, and feedback evaluation on a compact board, it supports precise positioning tasks in packaging machines, material handling cells, and printing lines without the need for separate standalone controllers.

Its real-time bus interface is SERCOS III, enabling cyclic position, velocity, and diagnostic telegrams with microsecond-level jitter. The MD2 expansion contributes 16 digital inputs for proximity switches and 16 digital outputs that can drive contactors or optocouplers directly from the drive stack. Encoder port EN2 supplies regulated 5 V at 350 mA supply current and uses a 35 ohm load resistance to maintain signal integrity over mixed-mode feedback cables. These resources allow the controller to read EnDat 2.1, 1 Vpp, or 5 V TTL encoders while still reserving bandwidth for high-speed axis updates.

The EN2 channel tolerates square-wave edges up to 1000 kHz, so fine-resolution incremental encoders can be processed without external multipliers. For step or frequency command applications, the MEM output remains reliable on cable runs of 40 m, and its driver can stream pulses at 1 MHz to stepper amplifiers or counters. Parameters are accessed through the RS-232 port, which sustains 115 kBaud on shielded lines. Absolute feedback over SSI is routed through a RJ12, 6-pin connector, letting position data travel alongside control signals while the MD2 interface supports 75 m extensions inside machinery.
