Product Description:

Bosch Rexroth Indramat manufactures the CSH01.1C-PL-ENS-EN2-NNN-NN-S-XP-FW controller as part of the CSH Advanced Controllers series. This unit functions as a command and feedback processor inside automated machines, converting digital instructions into drive-level signals for precise axis actuation. It relies on a parallel interface for real-time communication with upstream PLCs and downstream drives, allowing deterministic transfer of setpoints and status words. Its role is central to coordinating motion sequences, monitoring I/O states, and relaying status data within industrial automation architectures. It is suited for control tasks where command handling and axis response must remain closely synchronized.

The module’s power consumption is limited to 7.5 W, so thermal loading on the drive rack remains low. During start-up, an inrush draw of 4 A must be supplied, after which the internal regulators stabilize. Its analog output channel provides a 0 to +5 V range that can feed speed or torque references to external devices. The digital input block is rated at 24 V / 3 mA, while each digital output can source 24 V / 0.5 A for actuators such as contactors or indicator lamps. Signal timing is governed by a selectable 100 ms pulse width, and the controller does not include integrated safety technology. These electrical characteristics support stable signal exchange between the control section and connected field devices.

For high-resolution position feedback, the En2 port accepts EnDat 2.1 / 1 Vpp / 5 V TTL, delivering up to 350 mA at a regulated 5.0 VDC supply. The parallel Ens interface powers single-turn encoders with 500 mA at the typical 11.6 VDC level. A 16 In / 16 Out parallel I/O stack supports local deterministic handshaking over the dedicated parallel interface used for control communication. Configuration is carried out through the standard control panel, and pulse width filtering helps maintain stable edge recognition across all channels. This arrangement lets the controller process encoder feedback and local I/O activity within the same compact control stage.
