16. POSITIONING MODE
16.25 STOP METHOD FOR LSP （ FORWARD ROTATION STROKE END） OFF OR LSN
(REVERSE ROTATION STROKE END) OFF
Select a servo motor stop method for when LSP (Forward rotation stroke end) or LSN (Reverse rotation
stroke end) is off with the first digit of [Pr. PD30].
[Pr. PD30]
setting
Operation status
Remark
During rotation at constant speed
During deceleration to a stop
_ _ _ 0
(initial
value)
Erases the droop
pulses and stops the
motor.
Erases the home
position.
A difference will be
generated between
command position
and current position.
Perform a home
position return again.
_ _ _ 1
Erases the droop
pulse portion and
stops the motor.
Erases the home
position.
A difference will be
generated between
command position
and current position.
Perform a home
position return again.
_ _ _ 2
(Note 1)
Decelerates to a stop
with the deceleration
time constant
currently selected
with the point table or
the program.
Continues operation
for a delay portion of
the S-pattern
acceleration/decelera
tion time constants.
Maintains the home
position.
_ _ _ 3
(Note 2)
Erases the droop
pulse portion and
stops the motor.
Continues operation
for a delay portion of
the S-pattern
acceleration/decelera
tion time constants.
Maintains the home
position.
Note 1.
This will be the same motion as setting "_ _ _ 1" to [Pr. PD30] in the indexer method.
2.
This will be the same motion as setting "_ _ _ 0" to [Pr. PD30] in the indexer method.
Stop method selection for LSP (Forward rotation stroke end) off or LSN
(Reverse rotation stroke end) off
0: Quick stop (home position erased)
1: Slow stop (home position erased)
2: Slow stop (deceleration to a stop by deceleration time constant)
3: Quick stop (stop by clearing remaining distance)
