4.2.5 ALARMS 2061 TO 2068 (ZERO POINT RETURN AREA
ERROR)
Table 4.7
Cause of Trouble
Zero point return start
position was at zero
point side rather than
at deceleration LS side
Final distance of zero
point return is too
short, or, approach
speed is too fast.
Check Method
Try zero point return again while observing
the deceleration LS DECLS:
WI
#3073
Do(lst-axis)
#3073 D, (2nd-axis)
#3073
D, (3rd-axis)

#3073

(6th-axis)
#3073
D~(7th-axis)
#3073
D, (8th-axis)
As shown below an alarm results when
zero point return is made between DECLS
~nd
zero point. Note that this error check
>an
be performed only after power supply is
;urned OFF and the manual return to zero
point
has been completed.

ZERO POINT PULSE
Perform the zero point return by jog feed.
I’ry to change parameter for final distance.
Oompare the parameter for approach speed
with
parameter list.
Solution
Return it to the deceler-
ation LS or try the zero
point return again from a
more distant point.
Make final distance
(parameter) longer:
●
m
pm4451
tO
pm4458
● Approach speed:
pm2521 to pm2528
