Product Description:

The CSH01.1C-SE-ENS-EN2-MA1-S1-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. The module plugs into an IndraDrive power unit and serves as the motion processor that converts network commands into axis-level torque and speed references. It combines drive control, encoder evaluation, and safety logic on one card, allowing synchronized and secure motion in servo-driven packaging lines, gantries, and processing machines while reducing cabinet space and wiring.

Its base electronics draw only 7.5 W, so the backplane power supply remains lightly loaded even in multi-axis racks. At startup, the card can momentarily demand an inrush current of 4 A, a value used for fuse sizing and power distribution planning. Communication with the higher-level controller is handled through the optical SERCOS II interface, which provides deterministic cycle times for tightly coupled motion loops. The En2 encoder channel is powered internally at 5.0 V and up to 350 mA, supporting incremental encoders that report high-resolution position data. For emergency-stop chains, the safety circuitry terminates on a D-Sub 9 connector and accepts a 24 V, 3 mA pilot signal to supervise external relay contacts.

The second encoder supply, Ens, provides 11.6 V at 500 mA for SinCos or Hiperface sensors, while the associated TTL capture input accepts edge frequencies up to 400 kHz for rapid spindle feedback. The MA1 analog interface delivers a symmetrical control window of ±10 V on both input and output channels, and each direction uses 12-bit resolution to preserve fine speed references. For time-based events, the control section can generate pulses as long as 100 ms without external timers. When the safe-torque-off function is triggered, the card can sink or source machine interlock loads up to 24 V / 0.5 A, allowing direct actuation of contactors or valve coils without auxiliary relays.
