2. Er.601: Home return timeout
Cause:
•
When using the home return function (H05-30 = 1 to 5), the home is not found within the
time set in H05-35.
Cause Conrming Method Corrective Action
1. The home switch
fails.
•
There is only high-speed
searching and no low-
speed searching during the
operation of returning to
home.
•
After high-speed searching of
returning to home, the drive
keeps reverse low-speed
searching.
If the hardware DI is used, check
whether the DI function FunIN.31:
HomeSwitch (Home switch) has been
allocated to a DI and then check the
wiring of the corresponding DI. Make
the logic of the DI change manually
and observe whether the servo drive
receives the level change of the DI
through H0B-03. If not, the wiring of
the DI is incorrect. If yes, a fault occurs
on the operation of returning to home.
Please use the returning to home
function correctly.
If a virtual DI is used, check whether
the VDI is used correctly.
2. The search time is
too short.
•
Check whether the time for
home return set in H05-35 is
too short.
Increase H05-35.
3. The speed of the
high-speed searching
home switch signal is
too small.
•
Check the distance from the
initial position of returning to
home to the 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 the home
switch.
Increase H05-32
