Product Description:

Bosch Rexroth Indramat’s CSH01.1C-PL-ENS-NNN-MD1-L1-S-NN-FW is a control section option card from the CSH Advanced Controllers series. When fitted to an IndraDrive amplifier, it executes motion programs and handles drive diagnostics. It also furnishes mixed-signal I/O so packaging machines, gantries, and other multi-axis stations can coordinate position and speed in real time across the machine network. By combining motion control with local interface functions, the card supports compact drive assemblies that need both axis control and direct signal exchange.

The module’s analog interface is designed for precision. A channel input impedance of 160 kΩ prevents external transducers from being loaded, while each output can source 1 mA with a granularity of 19.5 mV/inc, enabling fine voltage references for torque or speed loops. Discrete control lines use defined thresholds: signals below 5 V are treated as logic-low, and anything above 15 V registers as logic-high, which helps resist noise on long cable runs. For position feedback devices, the board provides a regulated 12 V encoder supply. These resources allow the controller to combine sensor information with command values before forwarding consolidated data to the drive for deterministic actuation.

The card’s transistor drivers can sink up to 500 mA per channel, supporting pneumatic valve clusters and contactor coils. At power-up, the capacitive front end draws an inrush of 4 A, yet continuous demand remains within 17.5 W, allowing installation in compact fan-cooled cabinets. Device communication is handled by an RS-232 service port that reaches 115 kBaud over cables up to 15 m. Event processing tolerates pulse widths down to 100 ms, and the MD1 block presents 12 digital inputs and 8 outputs, while the parallel interface adds 16 inputs and 16 outputs for high-speed interlocks. A safety start inhibit is implemented with a 24 V, 3 mA monitoring input and a redundant 24 V, 1 A relay to interrupt the drive enable circuit when required.
