Product Description:

The CSH01.1C-ET-EN1-NNN-NNN-NN-S-NN-FW is a control section from Bosch Rexroth Indramat’s CSH Advanced Controllers series. Installed in an IndraDrive power unit, it processes position loops, manages fieldbus traffic, and interfaces with MHD and MKD motor families through a dedicated encoder channel. Within an automation cell, it serves as the command layer that synchronizes multiple axes in medium-performance packaging, gantry, or handling machines. Its control functions remain centralized in the drive so motion commands and feedback handling can be managed within the same platform.

The board provides two analog outputs that can source up to 7.5 W total from the low-voltage rail. Each channel is rated for a load of 5 kΩ, so standard differential inputs or torque references can be connected without overcurrent risk. Output granularity is set by a resolution of 19.5 mV/inc, allowing fine torque or speed trimming in closed-loop applications. When needed, a command can swing to a maximum of 5 V while sinking only 1 mA, which minimizes heat while maintaining signal integrity over shielded analog lines. Base analog performance is supplemented by an 8 V DC sensor supply that delivers 250 mA for external Hall or homing switches, so separate low-power sensor wiring is not required.

For networked motion, the control section carries a Multi-Ethernet communication module that negotiates protocols over a 100Base-TX link. Two RJ-45, 8-pin ports permit line topology wiring out to industrial cable lengths of 100 m without repeaters. Startup current is limited to 4 A with an inrush pulse of 100 ms, which helps prevent upstream fuses from tripping when drives energize at the same time. The unit has no integrated safety technology, so any SIL-rated functions must be provided by external safety devices.
