Removal
► Switch off the machine, disconnect it from the power supply and secure it to prevent
unauthorized reactivation. Observe the instructions in section 1.2 "Preparatory Work..." [}15].
► Remove the three fastening screws(1).
► Remove the cover(2) over the board.
► Unplug all electrical connections to the board (see above). You may want to mark the posi-
tions of these connections to make clear assignment easier later on.
► Remove the four fastening screws (see above).
► Remove the "sensor module universal".
Installation
► Follow the removal instructions in reverse order for installation. Also observe the following in-
structions:
CAUTION
Installation instructions
► Perform a embedded software download (see 6.4.11 "eSW Download (SW
70x)" [}130]).
6.4.8 Error "Gantry Crash"
A “gantry crash” error is established by calculating the position difference and speed difference for
both axes. A gantry crash error is signaled via the MGCUs and the CAN Bus. After the "gantry
crash" error message has been issued, both gantries need to be referenced.
