5.2.3 Troubleshooting of Warnings
Er.110: Setting error of frequency-division pulse output
Cause Conrming Methods Corrective Action
The number of
frequency-division
pulses of encoder
does not conform to
the specication.
For incremental encoder, the number of frequency-division
pulses cannot exceed encoder resolution.
Resolution of 20-bit serial incremental encoder is 1048576
P/r.
Resolution of 2500-PPR serial incremental encoder is
10000 P/r.
For absolute encoder, the number of frequency-division
pulses cannot exceed one fourth of encoder resolution.
Reset H05-17 (Encoder
frequency-division pulses)
correctly according to the
specication.
Er.601: Homing timeout
Cause Conrming Methods Corrective Action
1. The home
switch fails.
There is only high-speed searching and no
low-speed searching during operation of
returning to home.
After high-speed searching of returning to
home, the drive keeps reverse low-speed
searching.
If hardware DI is used, check whether DI function
FunIN.31: HomeSwitch (home switch) has been
allocated to a DI and then check wiring of the
DI. Make logic of the DI change manually and
observe whether servo drive receives level
change of the DI through H0B-03. If not, wiring
of the DI is incorrect. If yes, a fault occurs during
operation of returning to home. Please use the
returning to home function correctly.
If a virtual DI is used, check whether VDI is used
correctly according to the IS620P User Manual.
2. The search
time is too short.
Check whether time for homing set in H05-
35 is too short.
Increase H05-35.
3. Speed of high-
speed searching
home switch
signal is too
small.
Check distance from initial position of
returning to home to home switch. Then
check whether H5-32 (speed of home
switch signal at high-speed searching)
is too small, resulting in too long time of
nding home switch.
Increase H05-32.
Er.730: Encoder battery warning
Cause Conrming Methods Corrective Action
Battery voltage of absolute encoder is
lower than 3.0 V.
Measure battery voltage.
Replace a new battery with matching
voltage.
Er.831: AI zero drift too large
Cause Conrming Methods Corrective Action
1. AI wiring is incorrect
or interference exists.
Check wiring by referring to correct wiring
diagram.
Use shielded twisted pair cable and shorten
cable length.
Increase AI lter time constant:
AI1 lter time constant: H03-51
AI2 lter time constant: H03-56
2. The servo drive is
faulty.
Disconnect AI cable (input voltage is 0).
Check whether AI sampling value in group
H0B exceeds 500 mV.
If AI sampling value in group H0B exceeds
500 mV, replace the servo drive.
