Possible cause
There is no data transmission
between the CAN master and
slave communication cards.
Fault occurred to one of the
CAN slave VFDs.
The input terminal selects VFD
enabling, but the terminal signal
is invalid.
The contactor feedback circuit
is disconnected or in poor
contact.
The contactor feedback
detection time is too short.
The brake feedback circuit is
disconnected or in poor contact.
fault The brake feedback detection
time is too short.
The torque verification current,
moment force setting, and
torque verification fault
detection time are set
improperly.
The operating lever does not
return to the zero position.
The operating lever
zero-position signal is adhered.
Running speed too low.
The terminal gives both the
upward and downward
commands at the same time.
The terminal command is
detected at power-on.
Check whether the
communication card wiring is
loose or dropped.
Detect the CAN slave VFD and
analyze the corresponding fault
cause.
Check the input terminal setting
and terminal signal.
Check the contactor feedback
circuit.
