Product Description:

The CSH01.3C-PB-EN2-NNN-CCD-NN-S-NN-FW control section is produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. It mounts on an IndraDrive power unit and generates the real-time motion profiles that synchronize servo axes, spindles, and auxiliary actuators on automated production lines. By translating fieldbus telegrams into finely resolved analog and digital commands, the module serves as the central processing element that links supervisory PLCs to the electromechanical hardware on the machine floor. This arrangement lets the drive system respond quickly to command changes while maintaining coordinated axis behavior.

The module’s internal logic draws a base power of 8.5 W, so normal operation imposes minimal thermal load on the cabinet. At power-up, it withstands an inrush current of 4 A, which affects fuse and circuit breaker sizing. Two onboard analog outputs provide a resolution of 19.5 mV/inc, delivering precise voltage references, while the single analog input captures feedback for local monitoring. Each digital output can source up to 500 mA, allowing direct actuation of relays and signal lamps. The EnDat 2.1 / 1 Vpp / 5 V TTL encoder interface supplies incremental or absolute position data, and the En2 auxiliary channel accepts loads within the resistance and voltage range listed below.

For deterministic machine networking, the controller offers PROFIBUS-DP as its primary fieldbus, supporting cyclic process data exchange. Service access uses a 100Base-TX port that complies with the IEEE 802.3 standard and carries diagnostics at 100 Mbit/s. Internally, the signal blocks can toggle at up to 16 kHz, matching the requirements of high-bandwidth current loops in servo drives. The En2 encoder supply delivers 5.0 V at 350 mA and can drive sensors with impedances down to 35 Ohm without voltage sag. A serial maintenance channel reaches 115 kBaud over cables up to 15 m, providing an alternative access path when network traffic is unavailable.
