(7) Battery error (XA)
Switches on when battery voltage drops.
(8)
Error detection (XB)
Switched on by any of the errors in Chapter
8.
Switched
off
when
the error
is
reset. For resetting, refer to Section 3.5.2 (page 3-44].
(9) Zeroing complete (XC, XD)
Switches on to indicate the completion
of
zeroing. Switched off
at
the
start
of
the next process.
(10)
M
code
ON
(XE, XF)
The
ON
timing for this
signal
depends on
the
parameter setting
(see
Table 3.5, page 3-9, item 16).
If
set
in WITH mode, the
"M
code
ON"
signal
is
given
at
the
start
of
positioning, if set in AFTER
mode
it
is
given after positioning
is
complete. Switched
off
by the
"M
code OFF" signal. Remains
off
when the
M
code
is
not used
(M
code
=
0)
or
in test mode using the A6GPP.
(11) Positioningstart (Y10, Y11, Y12)
The leading
edges
of
the pulses cause the operations to
start as
shown in Table 3.9.
(12)
Zeroing start (Y13, Y14)
The leading
edges
of the pulses cause the operations to
start
as
shown in Table 3.9.
(13) Stop (Y15, Y16)
Terminates the current operation.
(If
the BUSY signal
is
on, the
"M
code
ON"
signal turns
off.)
For restarting the operation
see
Section 6.3.9.
(14) Jog
start
(Y17 to Y1A)
The motor
is
driven for
as
long
as
the jog
start
signal
is
on. When
it
is
switched off
the
motor
is
ramped down to
a
halt.
(15)
M
code OFF (YlB,
y1c)
I'
The leading edge
of
this signal switches the
"M
code
ON"
signal
Off.
