Remedy
After making an axis error reset (refer to [3] in Section
14.1), perform manual control operation (refer to Chapter
11) to move the axis to the position where the upper limit
signal (FLS) will not be turned OFF.
After making an axis error reset (refer to [3] in Section
14.1), perform manual control operation (refer to Chapter
11) to move the axis to the position where the lower limit
signal (RLS) will not be turned OFF.
Check the ON/OFF statuses of the stop command (output
signal/external input issued to AD75) and turn OFF the
active stop commands.
•
Output signals issued to AD75 ... Axis 1: Y13, Axis 2:
Y14, Axis 3: Y1C
•
External inputs ... External device connection connector:
Stop signal (STOP)
After checking the status of the stop command, perform
axis error resetting (refer to [3] in section 14.1) to remove
the error, then turn ON the start signal.
Turn ON the PLC READY signal (Y1D) with the BUSY
signals of all axes OFF.

•
Reset the axis error (refer to [3] in section 14.1) to cancel
the error.
•
Reexamine the sequence program that has turned ON
the positioning start signal [Y10, Y11, Y12], forward run
JOG start signal [Y16, Y18, Y1A], reverse run JOG start
signal [Y17, Y19, Y1B] or " Cd. 22 Manual pulse
generator enable flag".

<Zero point return retry>
0, 1
•
The zero point return retry function (refer to section
12.2.1) is validated (setting: 1).
•
Using manual control operation (refer to Chapter 11) to
move from the current position (zero point) and perform
machine zero point return.

<Zero point return speed>
1 to 1000000 [pulse/s]
1 to 600000000 [mm/min, etc.]
•
Calculate the distance of travel according to the speed
limit, zero point return speed and deceleration speed,
and determine the movement amount after activation at
the near-point dog so that the distance of travel is larger
than the deceleration distance.
•
Set a smaller zero point return speed.
•
Adjust the near-point dog position so that the movement
amount after activation at the near-point dog becomes
longer. (Refer to sections 8.2.5 to 8.2.7)

Correct the creep speed to within the zero point return
speed. (Refer to section 5.2.5)
