Product Description:

The CSH01.1C-SE-EN1-NNN-MD1-S1-S-NN-FW is a motion and logic controller from Bosch Rexroth Indramat in the CSH Advanced Controllers series. It coordinates servo drives and peripheral modules in automated machinery, acting as the central processing unit for axis control, fieldbus traffic, and integrated safety functions at the machine level. The unit is used in high-response packaging, printing, and material-handling lines where deterministic movement and compact cabinet space are important.

It ships in a Single-Axis configuration, so one drive channel is processed per card. Communication with the drive amplifier is executed over fiber-optic cables that carry the real-time SERCOS protocol, limiting ground loops and permitting deterministic cycle times. Position feedback arrives through the combined Resolver / HSF interface, allowing either analog resolver signals or high-speed digital data without extra adapters. The single-line operator panel supplies local status text, and twelve MD1 digital inputs accommodate limit switches or proximity sensors. Each transistor output point is rated at 500 mA, which is adequate for small solenoids or pilot relays without an interposing module. This arrangement supports direct connection to common machine sensors and output devices around the controlled axis.

For feedback excitation, the HSF channel provides 250 mA at 8 VDC, supporting automatic sensor initialization on power-up. The card supplies 8 MD1 sourcing outputs, and each group of four can deliver up to 1000 mA without derating. Resolver reference is driven at 4 kHz with 18.2 Vpp to maintain angle resolution across speed changes. Safety wiring uses a D-Sub 9 female connector fed by a 24 VDC logic rail, and the internal relay contacts are rated for 24 VDC / 1 A stop functions. The safety connector and relay contacts support stop-circuit integration without an additional interface module.
