Product Description:

The CSH01.1C-SE-ENS-EN2-NNN-NN-S-NN-FW is a motion-control processor card from Bosch Rexroth Indramat in the CSH Advanced Controllers series. Installed inside IndraDrive power sections, the card coordinates drive functions, fieldbus communication, and encoder evaluation for multi-axis machinery. It conditions EnDat and TTL feedback, handles analog command channels, and provides the control logic needed to keep servo axes aligned with machine commands during synchronized motion. The module is inserted into the left slot of a drive control section and acts as the command interface between higher-level PLCs and the drive power electronics.

During operation, the controller draws a nominal control bus of 24 V DC and has a base power consumption of 7.5 W, while the auxiliary SE expansion uses an additional 2 W. Each of its two analog outputs is digitized at 19.5 mV/inc, allowing small command steps to be reproduced with stable resolution during speed or torque control. Digital outputs can source up to 500 mA per channel, so relays or status lamps can be driven directly. The optional EN2 encoder interface supports cabling up to 75 m, which helps when motors or feedback devices are mounted away from the cabinet. For serial diagnostics, the onboard RS-232 port accepts cables up to 15 m and sustains 115 kBaud for local setup and service communication.

The dynamic behavior of the feedback channels is governed by the encoder ports on the card. The EN2 port can process square-wave signals up to 1000 kHz and uses an isolated 5.0 V rail that delivers 350 mA to the sensor head. The separate ENS port supplies 11.6 V at 500 mA and records TTL edges to 400 kHz, which suits high-speed encoder inputs. At power-up, the module presents an inrush of 4 A, limited to a 100 ms pulse, allowing standard 24-volt supplies and breakers to remain within their surge ratings during startup.
