Product Description:
The CSH01.1C-CO-EN2-MA1-MD1-L2-S-NN-FW control section is an automation controller from Bosch Rexroth Indramat within the CSH Advanced Controllers series. Designed as a plug-in module for Rexroth drive inverters, it generates command and feedback processing for servo axis hardware on production machinery, conveying equipment, and packaging lines. Its role is to interpret incoming references, process sensor feedback, and pass control values to the inverter power stage. By executing real-time motion routines, the unit coordinates torque, speed, and position loops while linking the drive with higher-level PLC or fieldbus networks.
This controller manages a single-axis drive, and its electronics draw only 7.5 W at the backplane, reducing cabinet heat. Field communication is handled through CANopen / DeviceNet, so parameter data and cyclic setpoints can be exchanged over a single twisted-pair bus. Encoder feedback is accepted through the EnDat 2.1, 1 Vpp, and 5 V TTL interface, and a dedicated 5 V sensor supply is provided on the same connector. This arrangement allows the controller to work with several common feedback signal types on compatible drive hardware. The MA1 option board delivers two differential analog inputs and two analog outputs, and the outputs have 12-bit resolution for velocity or process reference generation. A single-line display on the front panel allows parameter access without a laptop, and the RS-232 serial port supports service diagnostics with shielded cable lengths up to 15 m.
Discrete control is handled by the MD1 module, which offers 12 digital inputs for sensor states and eight transistor outputs for actuator drives. The analog outputs deliver a ±10 V span so proportional valves or legacy velocity loops can be driven from this controller. Functional safety is integrated as Safe Torque Off, activated through the 9-pin D-Sub STO connector, removing drive power within microseconds to meet stop category 0 requirements. This lets the drive shut off torque while the control section continues to manage signal and motion tasks.
