Overrun signal was
detected and the overrun
processing mode was
configured to alarm
If you do not want to alarm
immediately when the overrun
occurs, you can change the
overrun signal processing mode.
Overrun signal
connection error
(1) When the motor is in
forward rotation, it
encounters reverse
overrun signal.
(2) When the motor is in
reverse rotation, it
encounters forward
overrun signal.
Check over-run signal connection
and over-run terminal allocation.
(2) Stop timeouts too
short
(3) The setting of
braking torque is too
small.
(1) Reduce inertia or use brake
motor;
(2) Increase the stop timeout time
P0-30;
(3) Increase braking torque P3-32.
(1) Oscillation caused by
external forces
(2) Load inertia is large
and the setting of load
inertia ratio is wrong or
the gain is too small,
which leads to the
oscillation of
positioning.
(1) Check the source of external
force to see if there are any
problems in mechanical
installation;
(2) Increase the servo gain to
improve the anti-disturbance
ability;
(3) Acquisition speed curve
analysis; When the first three
peaks are convergenced after
pulse instruction completed (0.8* |
first peak | > | second peak | and
0.8* | second peak | > | third peak
|), the driver should not alarm,
which can adjust the relevant
threshold.
When the first three peaks speed
are not less than 300 rpm for three
consecutive times after the
completion of the pulse
instruction, the driver will alarm.
