Product Description:
The CSH01.1C-CO-ENS-EN1-EN2-NN-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It works as a communication and I/O interface that links servo drives with higher-level automation equipment. By handling fieldbus exchanges, encoder signals, and discrete inputs and outputs, the unit enables coordinated motion sequences and time-critical probing tasks on production machinery. This arrangement allows the control section to exchange network data, process feedback, and pass commands between the drive and the machine controller during synchronized operation.
One analog channel presents an impedance of 160 kΩ, so external sensors are not heavily loaded by the controller input stage. A complementary analog output delivers a reference level of 5 V, 1 mA for drive setpoints. Control communication uses CANopen and DeviceNet, supporting up to 127 devices on the CANopen segment and 64 on DeviceNet, which provides flexibility in node count. Digital inputs draw only 3 mA, while outputs can source up to 500 mA, making them suitable for relays or optically isolated loads. The EN1 connector provides an 8 V supply for incremental encoders, and the second encoder port uses 120-ohm differential termination with square-wave reception up to 1000 kHz. Internal logic rails are held at 11.6 V for the ENS interface, and the probe latch circuit resolves events with 1 µs accuracy. The high input impedance also helps preserve signal quality when the controller is connected to reference sources with limited drive capability.
Additional hardware provisions include a built-in line-end resistor of 124 Ω for the CAN backbone, which removes the need for an external terminator at the module. The EN1 feedback port can energize resolvers with a carrier amplitude of 18.2 Vpp, allowing mixed feedback types on the same drive. For switching higher-energy loads, the board routes a Form A relay rated at DC 24 V, 1 A. Service and diagnostics over the maintenance interface use RS-232 cables up to 15 m, which supports cabinet layouts without added repeaters.
