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
zero point return again while observing
the deceleration LS DECLS:
#3073
#3073
(2nd-axis)
#3073
(3rd-axis)
#3073
#3o73
(5th-axis)
#3073
(6th-axis)
#3073
#3073
(8th-axis)
As shown below an alarm results when
zero point return is made between DECLS
zero point. Note that this error check
be performed only after power supply is
OFF and the manual return to zero
has been completed.

ZERO POINT PULSE
Perform the zero point return by jog feed.
to change parameter for final distance.
the parameter for approach speed
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:

pm4458
●
