Product Description:
The CSH01.1C-SE-EN1-EN2-NNN-L2-S-K2-FW is a plug-in control section produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It is mounted inside an IndraDrive drive stack and supplies axis computation and field-level signaling. This allows servo drives to follow coordinated motion profiles in automated assembly cells, packaging lines, and other multi-axis systems.
The card is powered from a logic supply of 24 V DC and accepts an inrush current of 4 A when first energized. Its two analog outputs drive loads down to 5 kΩ, and each step changes the signal by 19.5 mV for fine setpoint resolution. Digital outputs source up to 500 mA, providing enough current for contactors or optical isolators. Parameter access and diagnostics over the service port reach a maximum rate of 115 kBaud, with RS-232 cabling allowed up to 15 m. A separate 5 V TTL interface supports incremental encoders that do not use the main bus. For real-time motion commands, the module communicates over SERCOS II; telegrams pass through an internal fiber ring so neighboring drives share the same cycle clock.
Safety and feedback features are integrated rather than added externally. The Safe Motion circuitry implements Safe Torque Off, removing gate signals to the power stage when a monitored fault occurs. Command and feedback telegrams travel over a fiber-optic medium that is immune to EMI typical of inverter cabinets. Resolver and HSF feedback are supported, and an EnDat interface running version 2.1 handles absolute position sensors without additional wiring. When sin-cos encoders are used, the controller expects a differential level of 1 Vpp, and it captures zero-speed alignment with a 100 ms pulse width. A D-Sub 9-pin female connector groups the safety contacts in one accessible interface.
