according to the set value
After the input terminal
selects inverter enabling,

The contactor feedback
detection time is too short
The brake feedback circuit
is offline or the connection
is not good;
The brake feedback
detection time is too short
The set values of torque
verification current and
torque and the detection

time of torque verification
are not reasonable
The joystick does not return
to zero position
When the lower hierarchical
contacts open, the upper
hierarchical contacts close;
When the joystick is at zero

Solution
parameter is set properly or
not;
Increase the maladjustment
detection time
Check the load and the
underload pre-alarm point
Check input terminal setting
and terminal signal
Check the contactor feedback
circuit;
Increase the detection time
P19.25 properly
Check the brake feedback
circuit;
Increase the detection time
P19.24 properly
Check the set values of
torque verification current and
torque and P19.26
Make the joystick return to
zero postition
Close the lower hierarchical
contacts before closing the
upper hierarchical contacts;
Check the joystick
Check the analog wiring
