Absolute value
servo encoder
battery low voltage
alarm (can shield
this alarm)
Usually the
problem of the
encoder itself, or
the power supply of
the encoder is
unstable.
In the absence of batteries, this
alarm may occur when the encoder
cable is disconnected.
Absolute value
servo encoder data
access alarm
Motor continues to
run in one direction,
encoder data value
is too large,
overflow
(1) F1-06=1 is used to clear cycles
of the absolute value encoder
(2) The alarm can be shielded by
P0-79=1.
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.
