Product Description:

The CSH01.1C-PL-ENS-EN1-MA1-L1-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Designed to plug into a compatible power section, the board coordinates drive, encoder, and I/O data so the connected servo axis can be synchronized with the plant controller. Within an automation line, it handles signal conditioning, position evaluation, and safety interlock functions that connect motion hardware to a higher-level PLC. This layout helps reduce cabinet wiring and keeps machine integration straightforward across varied platforms where compact, modular drive assemblies are preferred.

During operation, the control section draws a base power of 7.5 W, which helps limit heat inside the drive rack. All logic circuits are fed from an external 24 V DC supply, so a loss of the main drive bus does not immediately reset the controller or interrupt low-voltage logic. When first energized, the section can momentarily demand up to 4 A, which must be considered when selecting the upstream supply capacity. Command and status data are exchanged through a Parallel Interface, enabling direct handshaking with legacy machine controls without protocol conversion. For machine-level signals, the onboard PL area provides 16 digital inputs that are scanned in step with the drive cycle, which supports consistent timing between external status signals and axis control.

The MA1 analog block offers two differential inputs and two outputs, and each channel is converted at 12 bits to balance resolution with cycle time. Both outputs can source or sink signals across a linear range of ±10 V, allowing direct connection to proportional valves, tension controllers, or speed references. Axis feedback versatility is increased by the EN1 port, which supports resolver and HSF evaluation, while the ENS port supplies regulated encoder voltage for standard incremental feedback devices. A built-in safety feature called starting lockout keeps the power stage inhibited until valid enable conditions are present, providing predictable startup behavior after the system is powered.
