Product Description:

The Bosch Rexroth Indramat CSH01.1C-CO-ENS-EN2-MD2-S1-S-NN-FW belongs to the CSH Advanced Controllers series and serves as the command module inside IndraDrive systems. This controller interprets PLC instructions and supervises feedback from multiple encoders during closed-loop operation. It also issues pulse-width-modulated gate signals to the power stage so that coordinated servo motion can be achieved in automated assembly lines, packaging machines, and material-handling stations.

Its analog monitor channel delivers a maximum output of 1 mA at a reference level of 5 V, allowing drive status to be tracked by oscilloscopes or PLC A/D cards without loading the circuit. When the unit is first energized, it draws an inrush of 4 A. After startup, base consumption settles at 7.5 W, which helps with cabinet power budgeting. Discrete command lines tolerate up to 30 V, so standard 24 VDC sensors can be wired with headroom against transients. Each MD2 input sinks 3 mA, pulse commands may be as long as 100 ms without data loss, the CO connector is clamped by a locking screw tightened to 0.5 Nm, and the S1 terminal can supply 1.6 A of auxiliary power.

For high-resolution feedback, the EN2 interface offers an input resistance of 120 ohms and accepts square-wave signals up to 1000 kHz, enabling sub-microsecond edge detection for linear scales or resolvers. The ENS port filters these signals with a cutoff of 500 kHz while sourcing 500 mA at 11.6 V to the attached encoder, which helps prevent line drop on extended cables. Motion-related events, such as brake release, are actuated by the MD2 driver that can deliver 0.5 A per channel, matching most 24 VDC relay coils. Diagnostic data reaches supervisory computers over an RS-232 link that can span 15 m inside the control cabinet, allowing a laptop to connect without disrupting the fieldbus.
