Product Description:

The CSH01.1C-CO-ENS-NNN-NNN-L1-S-NN-FW is a plug-in control section from Bosch Rexroth Indramat that belongs to the CSH Advanced Controllers series. When inserted in an IndraDrive modular inverter, it executes axis interpolation, supervises fieldbus communication, and issues safety lockouts so production machinery follows commanded motion profiles. Its multi-slot design accepts dedicated CO, ENS, and L1 sub-modules, allowing the drive to condense feedback evaluation, command sequencing, and peripheral supply tasks on one compact board for cabinet-level automation.

The controller’s base electronics draw 7.5 W, while the CO mezzanine adds only 1 W to support CANopen messaging through a 5-pin spring terminal connector. A precision analog channel delivers 5 V reference signals, and each digital output can source 500 mA for external relays. A built-in CAN bus terminator of 124 Ω eliminates the need for external resistors, and a peak inrush current of 4 A must be considered when sizing the upstream supply. The ENS daughterboard attaches through a 15-pin D-Sub female connector, consumes 6 W, and provides 500 mA sensor power at 11.6 V DC. The L1 expansion section contributes an additional 2 W but carries no fieldbus signals, so total worst-case steady consumption stays within cabinet power budgets.

On the machine network, CANopen segments can extend to 500 m at 125 kbaud and accommodate up to 127 nodes, giving ample reach for distributed I/O and drive chains. The supply input tolerates a maximum inrush pulse width of 100 ms, ensuring standard circuit breakers remain within their trip curves. Safety startup is governed by Stop Category 0, meaning power to the motor is removed immediately on fault without timed deceleration. The CO port’s internal spring terminals accept stranded conductors without additional tooling.
