occurred to UVW signal
Check the wiring of UVW;
Encoder is damaged
F1-Er
[60] Failed to identify the
expansion card in card slot 1
There is data transmission
in interfaces of card slot 1,
however, it cannot read
the card type
Confirm whether the
expansion card inserted can
be supported;
Stabilize the expansion card
interfaces after power
down, and confirm whether
fault still occurs at next
power-on;
Check whether the insertion
port is damaged, if yes,
replace the insertion port
