Product Description:

The CSH01.1C-PB-ENS-EN2-MA1-L2-S-NN-FW is a motion and I/O control card produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. As a plug-in module for IndraDrive drive systems, it coordinates axis feedback, fieldbus communication, and analog process signals inside automated machinery. The unit translates encoder data, analog references, and network commands into drive-ready information so that servo amplifiers maintain precise torque, speed, and position loops across industrial production lines. Because these interface functions are handled on one card, the surrounding drive hardware can process machine signals without relying on a separate external module for each axis.

Its communication side is anchored by a PROFIBUS-DP interface that enters the board through a D-Sub 9-pin female bus connector, letting the controller exchange cyclic telegrams with higher-level PLCs at 12 Mbit/s. Position feedback is accepted on two encoder channels; the first supports IndraDyn / HIPERFACE / 1 Vpp signals, while the second accommodates EnDat 2.1 / 1 Vpp / 5 V TTL, giving the drive mixed incremental and absolute measurement options. This arrangement allows the control section to work with different feedback styles on the same platform, which is useful when machine axes do not all use the same sensor format. The integrated MA1 option card provides two differential analog inputs that sense command voltages up to ±10 V with a 12-bit resolution. Two analog outputs with the same range let the drive retransmit velocity or torque references to external devices.

Continuous board consumption is only 7.5 W, yet a startup inrush of 4 A must still be considered when the control supply is sized. All MA1 signals are routed through a 15-pin female D-Sub connector that accepts standard shielded cables, while a second 9-pin socket handles safety wiring. That link delivers the dual-channel logic for the certified Safe Torque Off function, and the control circuit remains valid with pulse widths up to 100 ms. The separate sockets keep process signals and safety channels on distinct connection points within the control section.
