Product Description:

The CSH01.1C-CO-EN2-EN2-MA1-S1-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It fits into modular drive stacks and supervises one servo axis, converting process inputs, encoder feedback, and fieldbus commands into precise motion profiles. By combining analog I/O, safety monitoring, and multiple communication links on a single board, the module streamlines machine-level automation tasks such as positioning, velocity regulation, and synchronized tooling. Its role is to coordinate command processing and feedback evaluation inside the drive so the connected axis responds consistently during changing operating conditions.

The board provides two external analog channels in each direction, so it can accept two inputs and supply two outputs without expansion hardware. Every input accepts a differential signal within ±10 V and is digitized at a resolution of 12 bits to preserve reference accuracy. The outputs reproduce setpoints over the same span with matching resolution. Motion computation is dedicated to a single axis, shown by an axis count of 1. For real-time coordination with PLCs, the unit supports the CANopen / DeviceNet control bus, while diagnostics are handled over an RS-232 link that operates from 9.6 to 115 kBaud.

Encoder feedback supports EnDat 2.1, 1 Vpp, or 5 V TTL standards and is powered from an isolated 5 V supply on the board. Network cabling attaches through a 5-pole spring terminal, which reduces installation time in multi-axis cabinets. Functional safety is handled locally through a Safety Technology I/O block on a D-Sub 9 female connector. It supervises inputs rated at 24 V / 3 mA and can switch outputs up to 24 V / 0.5 A. This arrangement supports emergency-stop and guard-lock circuits without requiring external relays.
