Product Description:

The CSH01.1C-PB-EN1-NNN-MD2-L2-S-NN-FW is a compact motion-control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside IndraDrive servo inverters, it coordinates axis commands and manages fieldbus traffic. It also performs safety-related shutdowns, making it a central element in automated assembly lines, packaging machines, and material-handling cells.

During power-up, the module draws a base inrush current of 4 A, then settles to a continuous base power demand of 7.5 W, values low enough to minimize cabinet heat while keeping logic circuits active. Internal timing routines use a base pulse width of 100 ms for diagnostics and watchdog cycles. For plant networking, the controller communicates over PROFIBUS; access is through the X30 interface, which terminates on a D-Sub 9-Pin Female connector and supports standard telegram rates up to 12 Mbit/s. Axis feedback is evaluated through an SSI encoder interface, allowing absolute position capture without additional converter cards. The MD2 option slot supplies 16 digital inputs and 16 digital outputs so that local sensors or interlocks can be wired directly to the drive instead of a remote PLC.

An auxiliary encoder channel is routed to a D-Sub 15-pin female connector for incremental or absolute transducers used on MKD, MKE, or MHD motor families. The onboard Hall and servo-feedback supply delivers 250 mA at 8 V, providing regulated power to those sensors without external supplies. Motion programs can also rely on the resolver interface, which excites windings with 18.2 Vpp at a carrier frequency of 4 kHz. For machine safety, the hardware implements Safe Torque Off, removing drive energy through hard-wired channels. The duplicated count of 16 digital outputs matches the 16 inputs, allowing symmetrical signal mapping for bidirectional I/O exchanges with higher-level controllers.
