Product Description:

The CSH01.3C-CO-EN2-EN2-CCD-S2-S-NN-FW is an advanced controller module from Bosch Rexroth Indramat within the CSH Advanced Controllers series. It is designed to coordinate servo drives, manage fieldbus messaging, and enforce safety functions in automated lines. Installed next to power inverters, the device supplies logic control and network arbitration so that multiple axes can be synchronized and supervised from a single embedded platform. Its compact format fits standard control racks and connects directly to upstream PLCs over the selected fieldbus.

During continuous service, the controller draws a base load of 8.5 W, easing cabinet ventilation requirements. A resident 124 Ω termination resistor is switched onto the CAN physical layer when this unit is the segment end, helping maintain proper signal integrity. Configuration and diagnostics are carried out through the 100Base-TX Ethernet engineering port, while cyclic control data move over selectable CANopen or DeviceNet protocols. Power-on energization produces an inrush of 4 A, so supply breakers must tolerate that short pulse. Acting as the master station, the module can address up to 64 DeviceNet / 127 CANopen nodes, and message timing is limited to a 100 ms maximum pulse width for cross communication under IEEE 802.3.

Position feedback is handled by two EN2 interfaces. Each channel presents 35 Ω input impedance and can deliver up to 350 mA at 5.0 V for encoder excitation. The ports accept EnDat 2.1 bidirectional serial encoders, analog 1 Vpp sine-cosine sensors, or 5 V TTL incremental signals, allowing mixed feedback technologies on the same controller. Mechanical connection is made through a D-Sub 9-pin female safety plug, and all shutdown functions rely on Safe Motion logic that is processed internally without external relays. Dual encoder monitoring supports redundancy checks so that motion can be stopped safely when position data deviate from calculated limits.
