Product Description:

The CSH01.1C-CO-EN1-EN2-NNN-NN-S-NN-FW is a plug-in control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It is installed in IndraDrive systems to process motion commands, manage feedback signals, and coordinate communication between the inverter and the higher-level machine control. By combining sensor interfaces with real-time communication links, the module supports deterministic control, interpolation tasks, and safety-related stop functions used in multi-axis industrial automation.

Analog resources on the board accept a differential input range of ±10 V, allowing reference signals to be read without additional scaling hardware. Its single analog output can source 1 mA across a span of 5 V for proportional control or external speed reference duties. For relay coils or brake release solenoids, the card provides a protected digital output that supports up to 0.5 A of sink current. The logic section draws 7.5 W from the DC bus, which helps keep internal power demand low. Position feedback is handled through two independent channels, with Encoder 1 supporting a resolver or HSF transducer and Encoder 2 supplying 5.0 V at up to 350 mA while recognizing EnDat 2.1, 1 Vpp, or 5 V TTL formats for incremental or absolute sensors on secondary axes.

At power-up, the section can draw an inrush current of 4 A, so upstream protection and supply wiring must be sized for startup demand. After startup, the RS-232 maintenance port supports point-to-point communication at up to 115 kBaud and can be cabled over distances of up to 15 m from the drive. Cyclic machine data are exchanged with higher-level controllers over the dual-purpose CANopen / DeviceNet interface. External command gating can also be synchronized through pulse signals of up to 100 ms, which helps coordinate control timing with other machine logic.
