Product Description:

The CSH01.1C-SE-ENS-EN1-MD1-S1-S-NN-FW is a modular motion-logic controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed in IndraDrive power sections, the unit manages drive regulation, digital I/O, and safety monitoring so servo axes can follow programmed motion profiles in industrial automation cells, packaging machinery, and material-handling gantries. Through its onboard processor, the card executes position loops, supervises fieldbus traffic, and passes time-critical status data to higher-level PLCs. This arrangement allows the controller to coordinate motion commands with local safety and I/O functions inside the same drive platform.

It interfaces with drives over the SERCOS real-time bus and transmits telegrams through fiber-optic cables, which helps reduce electrical noise on long runs. During idle operation, the controller draws 7.5 W, helping keep cabinet power demand low. Analog diagnostics use a channel rated at 5 V / 1 mA, while twelve MD1 digital inputs accept 24 V / 3 mA signals from limit switches or sensors. Eight transistor outputs share a common supply to drive auxiliary actuators, and the single-line display presents axis codes for local status reading. The optical link also helps maintain signal quality where routing passes near power conductors.

At power-up, the supply sees 4 A for no longer than 100 ms, allowing standard circuit breakers to remain closed. Two encoder supplies are provided: the EN1 port delivers 8 V for TTL or incremental encoders, and the ENS port provides 12 V for high-resolution serial devices. Resolver feedback is supported through a 4 kHz carrier with 18.2 Vpp amplitude, giving absolute shaft angle even during power interruptions. Safety wiring terminates on a D-Sub 9 female connector that follows the S1 designation, and a separate relay path can switch 24 V loads up to 1 A when isolation is required.
