Product Description:

The CSH01.1C-PL-ENS-EN2-MEM-S1-S-NN-FW advanced controller is produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. Mounted on an IndraDrive power section, this card executes real-time axis control, interpolation, and safety logic for servo drives used in factory automation. Its role is to translate high-level machine instructions into deterministic pulse and direction data, letting packaging lines, robotics cells, and conveyor modules maintain coordinated motion without an external PLC.

It exchanges data with upstream control layers through a Parallel Interface, providing microsecond-level strobes instead of cyclic fieldbus polling. Encoder channel 1 supplies 11.6 V at up to 500 mA, a capacity large enough for SinCos sensors with integrated status LEDs, while channel 2 offers 5.0 V and 350 mA for TTL feedback or Hall arrays. A hardware interpolator refreshes emulated quadrature signals at 1 MHz, keeping resolution intact during high-speed spindle work. Digital I/O is equally direct, because the board accepts 16 parallel inputs that are latched synchronously to the motion cycle and mirrors process states to 16 sourcing outputs. Service diagnostics are performed over RS-232 at 115 kBaud, allowing service access and trace collection without occupying the main automation network.

Integrated safety resources remove the need for separate relays. A supervised input line draws 3 mA from a 24 V emergency-stop circuit, and when that loop is interrupted the controller energizes solid-state outputs rated at 24 V / 0.5 A to drop contactor coils. For redundancy, a relay contact can switch 1 A at the same voltage. The matching set of 16 transistor outputs pairs with the earlier input bank, simplifying wiring in control cabinets, while dedicated encoder power rails improve noise immunity by isolating sensor returns from logic ground.
