Possible cause
The two inserted expansion
cards are of the same type.
type
No electric level variation
occurred to UVW signal.
No data transmission between
card
the communication card and the
host controller (or PLC).
There is no data transmission
between the CAN master and
slave communication cards.
Motor overtemperature input
terminal is valid.
The temperature detection
resistance is abnormal.

Confirm whether the expansion
card inserted can be supported.
Stabilize the expansion card
interfaces after power-off, and
