Since communication in the EHD system is solely wire-based, the installation position of steering system components is not limited to a single location on the machine. Taking the cable length limitations and environmental requirements into account, the installation positions are up to the system integrator. © Danfoss | December 2022 AX436683569858en-000101 | 7... -
Page 8: Joystick Overview
In applications where the machine allows auto-guided driving, this button can be used for disabling an active drive mode. This finger function is considered safety-relevant, because the operator needs to be able to reliably disable auto-steering. © Danfoss | December 2022 AX436683569858en-000101... -

Page 13: Operation Modes
The joystick will transmit SAE-J1939 messages every 50 ms per CAN channel. Operation modes JS1-H Steer by Wire implements different operating modes in software: 1. Bootloader Mode 2. Normal Operation 3. Safe State © Danfoss | December 2022 AX436683569858en-000101 | 13... -
Page 14: Bootloader Mode
If detected, the bootloader will start the software and the joystick will run in Normal Operation. If no software is installed, the affected MCU will remain in Bootloader Mode. This can be verified by checking the Danfoss PLUS+1 ® Service Tool. -
