Product Description:

The CSH01.1C-NN-ENS-NNN-MD1-L2-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It plugs into compatible IndraDrive power sections and manages signal processing, safety, and feedback functions so the overall drive can position servomotors in automated machinery. By separating high-level logic from the power electronics, the unit keeps control functions modular and leaves cabinet wiring unchanged when used with matching power hardware.

This control section is powered through a dedicated control supply of DC 24 V, which isolates its electronics from the mains circuit. Fieldbus lines are not equipped, so network communication requires a separate option card when that function is needed. For local wiring, the board provides 12 extension inputs that can be assigned to drive functions such as homing triggers, reference switches, or sensor interlocks. Encoder feedback enters through a shielded cable on a D-SUB 15-pin female connector, and the interface supports feedback formats listed as IndraDyn, Hiperface, 1 Vpp, and 5 V TTL. This arrangement keeps feedback processing inside the controller and helps maintain low-latency position control.

Power for connected feedback devices is supplied internally at 11.6 V with a current limit of 300 mA, which is suitable for many single-turn and multi-turn encoders without a separate external supply. Functional safety is handled by the integrated Safe Torque Off circuit, which removes drive output torque without depending on software action when the safety chain opens. The safety connection uses a dedicated D-SUB 9-pin female connector, allowing the STO channel to remain separate from standard control wiring. This layout supports hardware-based motion disable paths in systems that require a dedicated safety circuit.
