Product Description:
The CSH01.1C-PB-EN1-EN2-MEM-S2-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted inside IndraDrive power units, this module directs servo axes, processes encoder feedback, and relays motion commands to the drive. By combining analog monitoring with fieldbus communication, it serves as the intermediary between higher-level PLCs and the drive inverter, allowing coordinated positioning and speed control in industrial automation systems across integrated motion applications.
This version provides two analog channels with an input resistance of 160 kΩ, while each output can source up to 1 mA. The unit has 2 analog outputs that support velocity or torque setpoints. Controller losses remain low, with a basic power draw of only 7.5 W, which helps minimize cabinet heat. For direct position feedback, Encoder 1 uses the HSF/RSF interface and is supplied with 8 V; it supports SSI absolute emulation and can switch to incremental operation through the absolute and incremental emulation mode. Encoder 2 accepts EnDat 2.1, 1 Vpp, or TTL signals and is powered from a 5 V rail. Together, these interfaces enable mixed feedback combinations such as linear scales on channel 1 and rotary encoders on channel 2.
The master fieldbus is PROFIBUS, accessed through a D-Sub 9-pin female connector. When the module is used as a segment repeater, it draws 75 mA from the bus and is energized by a separate 5 V logic supply. Safe Motion functionality is integrated, giving the drive the ability to execute STO, SS1, and other safety-related stop functions with a rating of SIL2 / Cat. 3 PL d. These capabilities support machinery safety functions without adding external safety relays, while keeping wiring and diagnostic data on the same network.
