Product Description:

The CSH01.3C-CO-EN1-EN2-CCD-NN-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in a modular drive cabinet, the unit functions as the intelligence layer between a plant-level PLC and Indramat power stages. By interpreting motion commands, reading encoder feedback, and issuing finely timed gate pulses, it coordinates servomotor position, velocity, and torque in packaging lines, gantry loaders, and other process equipment. It also passes status information between the higher-level controller and the power electronics so multiple axes can remain synchronized during dynamic machine cycles.

Two onboard analog channels generate reference or diagnostic voltages. Each channel can source up to 5 V / 1 mA with a step size of 19.5 mV/inc. The unit has 2 outputs, allowing simultaneous delivery of velocity and torque setpoints to ancillary devices. Base electronics draw only 8.5 W, so cabinet heat rise remains limited even when the relay switches loads rated at DC 24 V / 1 A. CANopen and DeviceNet ports manage cyclic control communication, while the SERCOS III master interface handles cross-communication telegrams among neighboring axes. Resolver and HSF signals are accepted on Encoder Interface 1, and Encoder Interface 2 accepts EnDat 2.1, 1 Vpp, or 5 V TTL formats for closed-loop operation.

Pulse trains to the connected inverter are switched at a maximum of 16 kHz, supplying the control loop with ample bandwidth for high-speed positioning. For applications that need finer servo resolution, the incremental output of Encoder 1 is refreshed at 4 kHz and uses a dedicated supply of DC 8 V / AC 18.2 Vpp. Encoder 2 receives a stabilized 5 V feed, which helps maintain clean feedback signals during operation. Deterministic traffic over the integrated Ethernet port conforms to the IEEE 802.3 standard, permitting streamlined network wiring. An auxiliary 5 V rail powers external sensors, and the module supports analog cross-checking through its analog outputs to monitor command consistency during safety sequences.
