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

(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

Approach speed:

pm2521 to pm2528
