Product Description:

The CSH01.1C-PL-ENS-EN2-EN2-NN-S-NN-FW is a controller module in the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. Mounted beside IndraDrive power units, it forms the command layer that regulates motor current, speed, and position for multi-axis machines. The board provides three on-board encoder sockets, consisting of one ENS connection and two EN2 connections, so feedback devices can be connected without external adapters. It also offers parallel and serial communication links so the drive can connect with PLCs, HMIs, or diagnostic terminals in industrial automation cells.

For stable logic operation, the unit uses a base supply of DC 24 V, and the internal electronics consume only 7.5 W under nominal load. When power is first applied, the input can surge to 4 A, but this inrush is limited to 100 ms, which helps prevent nuisance trips on the cabinet supply. Once energized, motor phase currents are evaluated and updated every 125 µs, supporting tight torque regulation on fast-moving axes and improving response during rapid load changes. Control commands arrive through the dedicated parallel interface, while service data is exchanged through an RS-232 port. The module does not include safety technology, and a single 1 N/O relay output is available for auxiliary signaling.

Feedback distribution is handled through the ENS socket and the two EN2 channels. Each EN2 path uses 35 Ω termination and can source up to 350 mA at 5 V for incremental encoders, while the ENS output delivers 500 mA at 11.6 V to support absolute sensors. Two analog outputs can be mapped to velocity or torque demands from the host PLC, allowing analog process variables to operate alongside the digital command stream. These electrical figures set the allowed load selection and wiring practices so the controller can maintain commanded bandwidth without exceeding its thermal or supply limits.
