Product Description:

The CSH01.1C-PL-ENS-EN2-NNN-S2-S-XP-FW control section belongs to the CSH Advanced Controllers series produced by Bosch Rexroth Indramat. It functions as a motion and safety processor inside IndraDrive systems, converting position commands into real-time switching patterns for power stages while supervising encoder feedback and coordinating status exchange with the drive electronics. By integrating Safe Motion technology, the unit lets a drive system handle standard motion control and safety-related monitoring in one compact module that links higher-level PLC networks to the inverters used on automated production lines.

The board communicates through a parallel interface, and its mixed-signal terminals support coordinated axis tasks during machine operation. Two analog channels can source 1 mA or 5 V for reference transducers, and one digital path delivers up to 500 mA for solenoid or lamp actuation. Discrete control is organized as 16 In / 16 Out, giving deterministic bit updates along the backplane for command and status handling. Within the EN2 encoder supply, a 35-ohm load resistor keeps the 350 mA source current stable during transient shorts while the 5.0 V rail stays within tolerance. A single-line panel display reports parameter codes, the pulse generator stays within the 24 V / 1 A safety-relay ceiling, and Safe Motion logic supervises stop functions without requiring separate relay hardware.

Power sequencing introduces additional electrical limits for startup and continuous operation. Inrush current reaches 4 A at startup, yet steady operation requires only 7.5 W, which helps limit continuous heat buildup inside the compact control section during normal use. The ENS feedback rail maintains 500 mA at 11.6 V so secondary encoders remain powered during bus drops, and internal watchdog traffic holds a pulse width of 100 ms to provide a clear timing window for safety diagnostics before gate signals are re-enabled.
