Serial port communication error
Reset by pressing the STOP/RESET key, seek for
service support
The fault alarm parameters are set
improperly.
Modify the P15.03 and P97.00 settings
The host device does not work.
Check if the host device is working and if the wiring
is correct.
Er.rLy
Abnormal
contactor

reference
command lost
During the frequency main reference or
the torque command selection analog
current reference, the analog reference
signal is disconnected or too low (less
than 2mA).
Check the wiring or adjust the input type of the
reference signal

Operation panel
parameter
copying error
The operation panel parameters are
incomplete or the operation panel
version is inconsistent with main control
panel version.
