In the case of no battery,
unplugging the encoder cable may
cause this alarm.
Absolute value

value overflow
The motor runs in one
direction continuously,
the encoder data value is
too large, overflow
① Set F1-06 = 1, clear the
absolute encoder's multiple turns;
② Set P0-79 = 2, the alarm can
be shielded.
The error

The error between motor
encoder feedback and
grating encoder feedback
(user command
resolution) exceeds the
setting value of P9-02
① Mechanism error. The motor
outputs the shaft position directly
and reaches the moving platform
through the mechanism. The
feedback of the grating ruler is
directly from the moving
platform, and there will be errors
in it after passing through the
synchronous belt or lead screw
② Grating ruler installation is not
parallel
③ Set P9-05 to P9-08 reasonably

When P9-02 is set to 0,

The error between the

Check that the correct P9-05 ~
P9-08 is selected for the
mechanism and power on again.
Timing error in

① The number of
consecutive errors in

sequence is greater than
the value in P0-68
② Check the arrangement of
transmission cables to ensure that
the strong and weak current are
wired separately.
③ High current equipment is
supplied separately.
④ The grounding is good.
The received encoder
