Product Description:

The CSH01.1C-NN-NNN-NNN-NNN-L2-S-NN-FW is an advanced drive controller manufactured by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. Mounted on an IndraDrive power module, it executes current, speed, and position regulation for one servo axis while also coordinating auxiliary machine signals. The device provides onboard logic, a removable single-line display panel for direct parameter access, and multiple field wiring terminals for local control and signal connections. In industrial automation, it links the motion task generated by the PLC with the power electronics that energize the motor, delivering deterministic control that preserves product quality and machine throughput.

Its current loop is refreshed every 125 µs, giving the drive sufficient bandwidth to suppress load-induced torque ripple. The module accepts one differential analog feedback channel with a resolution of 1.23 mV/inc, allowing precise capture of sensor voltages such as torque or tension signals. Two programmable analog outputs are generated at 19.5 mV/inc so external recorders or valve amplifiers receive finely graduated setpoints. Up to 11 digital inputs can be wired for start, limit, or homing commands, and as many as 4 digital outputs are available to activate contactors, pilot lamps, or interlock relays.

Functional safety is implemented through the integrated Safe Torque Off channel that removes drive energy without relying on mechanical contactors. Motion data or diagnostic messages are exchanged over the built-in RS232 service port, which is useful when higher-level fieldbus hardware is not installed. Each digital input draws only 24 V / 3 mA, minimizing load on sensor power supplies, while the single relay contact can switch control circuits up to DC 30 V / 1 A for tasks such as brake release or axis-ready signaling in low-power control circuits.
