Product Description:

The CSH01.1C-PB-ENS-NNN-MA1-S2-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Housed in an IndraDrive servo inverter, it links motion commands from upper-level PLCs to drives and feedback devices on the machine. The section accepts clip-on option cards, allowing fieldbus communication, encoder evaluation, and analog processing to be combined in one compact slot. In multi-axis systems, it handles coordinated positioning, distributes safety states, and returns diagnostic data to the control system. This arrangement helps centralize motion-related functions within the drive platform.

The integrated analog board provides 2 inputs and 2 outputs with 12 bits of resolution for accurate setpoint and feedback scaling. Each channel operates on a bipolar range of ±10 V, allowing direct connection to common velocity or torque references. Signals enter through an analog D-Sub 15 female connector, while the base stage can source 5 V at 1 mA on two reference outputs for external potentiometers. Field communication to the host control system occurs over PROFIBUS-DP. Local parameter access is available through the RS-232 serial port. The MA1 multifunction module has low power demand, which helps keep the added control load modest inside the inverter.

An independent encoder interface terminates on a 15-pin D-Sub female connector and delivers regulated power at 12 V to sensors that meet the S2 requirement. Supported feedback formats include IndraDyn S, 1 Vpp, Hiperface, EnDat 2.1, and 5 V-TTL, allowing the controller to work with several common motor feedback types. Functional safety is handled by the integrated Safe Motion set, enabling monitored stop and limited-speed functions without external relays. Power consumption of the ENS encoder supply remains at 6 W, which helps limit cabinet heat load. The separate encoder connection also allows feedback processing without requiring an additional external evaluation module.
