2-speed positioning operation
Change point FX3U-1PG FX2N-1PG Replacement point
When the operation direction
is different between the 1-
speed and the 2-speed
The motor reaches the target address
I at the operation speed I, reverses the
operation direction, and then reaches
the target address II at the operation
speed II.
The motor reaches the target address
II at the operation speed II from the
beginning.
Confirm that no problem is expected
in the system when the motor
reverses the operation direction if the
operation direction is different
between the 1-speed and the 2-
speed.
1-speed positioning operation can be
substituted for operation of the FX2N-
1PG.
Change the sequence program as
needed.
Operation when the travel
amount at the 1-speed is
small
(When the time required to
perform acceleration until the
operation speed I is longer
than the travel time until the
target address I)
The motor performs acceleration until
it reaches the target address I.
The motor starts with operation speed
II from the beginning.
Confirm that acceleration until the
operation speed I causes no problem
in the system.
1-speed positioning operation can be
substituted for operation of the FX2N-
1PG.
Change the sequence program as
needed.
Operation when the travel
amount at the 2-speed is
small
(When the time required to
perform deceleration from
the operation speed I is
longer than the travel time
until the target address II)
The motor starts deceleration at the
end of the 1-speed, and stops
immediately when it reaches the target
address II.
The motor starts deceleration before it
reaches the target address I, and
stops when it reaches the target
address II.
Confirm that immediate stop causes
no problem in the system.
1-speed positioning operation can be
substituted for operation of the FX2N-
1PG.
Change the sequence program as
needed.
