Product Description:
The CSH01.1C-NN-EN2-MEM-MA1-L1-S-NN-FW control section is built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It plugs into IndraDrive power units and orchestrates servo axes in packaging, printing, and assembly cells, translating fieldbus commands into precise current, velocity, and position loops inside the drive. By handling both feedback processing and safety-related start inhibition, it serves as a compact automation control center rather than an external standalone PLC.
The controller samples analog feedback with a 12-bit converter, providing adequate resolution for temperature, pressure, or torque sensors. Two dedicated analog input ports accept single-ended signals, so the module offers 2 channels for acquisition, while another pair delivers voltage outputs for reference generation to external devices. Wiring distances depend on the use of sense leads: feedback-compensated installations can stretch to 75 m, whereas basic runs are limited to 50 m. All encoder emulation signals exit through a driver that is galvanically isolated, which helps minimize ground loops, and the standard front-mounted control panel allows local parameter adjustment. Because emulation power is generated internally, an external supply is not required, and the supported absolute and incremental formats simplify retrofitting of legacy motion axes.
The internal encoder supply provides 350 mA at 5.0 V, which is enough for typical SinCos or TTL transducers even on long cables. Safety interlocks are routed through a D-Sub 9 female connector; the input expects 24 V / 3 mA to arm the drive, while the relay-rated output can source 24 V / 1 A to downstream contactors. A separate D-Sub 15 female, labeled MA1, hosts additional digital I/O and status lines. Configuration variant L1 activates the starting lockout channel for SIL-related safety functions without extra hardware.
