Product Description:

The CSH01.1C-PL-EN1-MA1-MD2-NN-S-NN-FW controller module is produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. Designed for drive-based automation, this plug-in card governs motion axes, processes digital and analog feedback, and coordinates I/O tasks inside Indramat servo drive racks. By combining multiple feedback formats with field-oriented logic, the unit serves as the central command element that links servo drives to higher-level PLCs in industrial machinery and material-handling systems.

The module’s base electronics consume only 7.5 W, reducing cabinet thermal load during continuous operation. Command data are exchanged over a Parallel Interface, so position words reach the drive without protocol overhead. The card supplies DC 8 V to MKD, MKE, and MHD encoders and also supports R0, R1, S0, and M0 resolvers. The safety monitor draws 250 mA from the HSF rail, simplifying fuse sizing. Each MA1 board has two analog channels rated at ±10 V, with 2 inputs and 2 outputs for direct loop wiring. A front-mounted single-line display shows operating status and error codes.

Startup transients are limited to an inrush of 4 A, which sets the minimum rating for the drive backplane’s pre-charge circuitry. Each MA1 channel digitizes feedback with 12-bit resolution, matching the granularity expected for fine speed regulation in packaging or printing lines. The MD2 extension offers sixteen transistor outputs rated 24 V / 0.5 A and also provides sixteen corresponding inputs, bringing the total MD2 I/O count to 16 inputs and 16 outputs. Independent of option cards, the base parallel port adds another 16 inputs and 16 outputs for fast handshake tasks. Resolver feedback is supported through a carrier of AC 18.2 Vpp at 4 kHz, and the timing logic can generate pulses up to 100 ms wide for short-duration actuator commands.
