Product Description:

Bosch Rexroth Indramat manufactures the CSH01.1C-PL-ENS-NNN-NNN-S1-S-NN-FW controller card within its CSH Advanced Controllers series. This plug-in module functions as the central intelligence for IndraDrive power sections, processing feedback, fieldbus traffic, and local I/O so the drive can execute position, speed, and torque loops in industrial automation lines. By concentrating the control logic on a removable card, the design allows fast adaptation of axes to application-specific sensor configurations while maintaining a consistent power platform.

The electronics draw a control supply of 24 V, and at power-up they can momentarily absorb an inrush of 4 A, which is important when sizing cabinet fuses and auxiliary power supplies. During steady operation the board demands only 7.5 W, limiting thermal rise inside closed drive racks. One isolated analog channel provides up to 5 V / 1 mA for tasks such as transducer reference or actuator biasing. Internal position capture is handled by an encoder converter with 12-bit resolution, translating differential TTL signals into numerical counts for the drive.

Dedicated encoder power is delivered at 11.6 V with a maximum draw of 500 mA, allowing many incremental encoders to be supplied directly without external regulators while still supporting TTL edge rates up to 400 kHz and pulse widths to 100 ms. Host communication uses an RS-232 port that sustains 115 kBaud over cables as long as 15 m, simplifying setup from a laptop on the plant floor. For machine-level logic the module exposes 16 parallel digital inputs plus an equal number of sourcing outputs, and it includes separate S1 channels rated 24 V/0.5 A for higher-current loads. These discrete interfaces let the drive react to limit switches and forward status bits to a PLC without extra interface hardware.
