Product Description:

The CSH01.1C-CO-EN2-EN2-MA1-NN-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive cabinet, the card manages motion for one motor axis, handles fieldbus messaging, and conditions feedback from incremental or absolute encoders. In automated equipment, it closes real-time position loops, passes setpoints between the higher-level controller and the drive power stage, and helps maintain coordinated axis response during changing load conditions. Because it is the control section rather than the power module, its main tasks are signal processing, feedback evaluation, and network communication.

This controller supports a single-axis configuration and communicates with external devices through CANopen as well as DeviceNet for synchronized network operation. Nine digital inputs are rated at 24 V, 3 mA, and four digital outputs can switch 24 V loads up to 0.5 A for contactors, relays, or indicator lamps. Each EN2 encoder port is supplied with 5.0 VDC, and the combined current draw for both ports is 350 mA, which allows direct connection of EnDat or TTL sensors without a separate supply module. The MA1 option also provides 2 differential analog input channels for process signals such as tension, pressure, or trim references. This arrangement lets the controller collect machine signals directly from sensors and switches while returning simple status commands to surrounding equipment.

The drive electronics receive logic power between 19 to 30 VDC, which allows the control section to start even when the main three-phase bus is off. An Ethernet-based setup link presented as 100Base-TX supports parameter changes, diagnostics, and trace capture over a standard network connection. Two EN2 terminals accept incremental or EnDat 2.1 encoders and can process 1 Vpp or 5 V TTL signals for high-resolution position capture. The MA1 option includes analog outputs with a ±10 V range, and an additional onboard analog output supplies 0 to 5 VDC for a scaled status signal on external meters or interface devices. Keeping the logic supply separate from the main bus also allows communication and status monitoring during startup and controlled shutdown states.
