6.4.3
Motor rotating direction
The motor rotating direction is determined by the contents of parameters number
11
and number
18,
..
and the wiring orientation between the
PGU
and the
DRU.
Rotating direction
The direction the motor turns when the machine is moved by a forward pulse may also be
changed by the wiring and the machine specifications.
Correct connection
of
emergency limit switches
Notes: When
PARA
number
12
is
IO',
pulse generation
stops
when an emergency
LS
is turned
ON.
When
PARA
number
12
is
"l',
pulse generation
stops
when an emergency
LS
is turned
OFF.
*
Install the LSF and
LSR
to positions a little away from the normal operating range.
When an emergency LS is actuated, the motor stops running. Manually give a STOP input
to the PGU to reset errors before restarting operations.
(Memo)
To
enable servo motor operation, LSF and LSR must be connected
to
the
DRU,
and the setting on
the PGU must be normally
ON
(PARA number
12
"1
")
or OFF (PARA number
12
"0").
In this case, when the
DRU
is automatically stopped by an actuation of LSF or LSR, the
PGU
cannot
recognize the stop state. Therefore, use the auxiliary LSF and LSR which operate before
LSF
or
-
LSR operates and are connected
to
the PGU for improved operations control.
