Appendix C-3-2 Differences in individual operation modes

Differences in individual operation modes of FX
JOG operation
Change point
The
corresponding to 1 user unit.
However, the FX
pulse even if the value "Position data
multiplier x Pulse rate" is smaller than
Inching travel amount
the feed rate in the machine system
setting or combined system setting
and the pulse number required for the
travel in 1 user unit is less than 1
pulse.
DOG type mechanical zero return operation
Change point
The motor starts the DOG search
DOG search operation when operation even when the direction of
the forward limit/reverse limit the forward limit or reverse limit in the
is ON ON status is the same as the zero
return direction.
The motor stops at the forward limit (or
reverse limit) and the forward limit/
reverse limit error occurs if the DOG
cannot be detected while the motor
Operation when the DOG
starts
cannot be detected
reverses the operation direction at the
reverse limit (or forward limit) and then
reaches the forward limit (or reverse
limit).
Interrupt 1-speed positioning operation
Change point
The motor decelerates when the
interrupt input is detected, and stops at
the target address I.
Operation when the travel
amount is small
(When the time required to
perform deceleration from
the operation speed I is
longer than the travel time)

The motor does not perform the
operation when the direction of the
forward pulse stop (forward limit) or
reverse pulse stop (reverse limit) in the
ON status is the same as the zero
return direction.
The motor stops at the forward limit (or
reverse limit) but no error occurs if the
DOG cannot be detected while the
motor starts the zero return operation,
reverses the operation direction at the
reverse limit (or forward limit) and then
reaches the forward limit (or reverse
limit).
FX -1PG
2N
The motor does not accelerate until
the operation speed I is reached, and
performs acceleration only until it
reaches a speed so as to achieve
"Travel amount during deceleration =
Target address I".

Appendix C-3 Differences in Operation
Replacement point
Confirm that no problem is expected
in the system when the travel amount
generated by 1 inching operation is
large if the pulse
corresponding to 1 user unit is larger
than 1 pulse.
Change the sequence program as
needed.
Replacement point
Confirm that no problem is expected
in the system when an error occurs at
the forward limit or reverse limit, the
zero return operation is executed
from the corresponding limit position,
and the motor reverses the operation
direction.
Change the sequence program as
needed.
Confirm that no problem is expected
in the system when an error occurs at
the forward limit or reverse limit, the
zero return operation is executed
from the corresponding limit position,
and the motor reverses the operation
direction.
Change the sequence program as
needed.
Replacement point
Confirm that no problem is expected
in the system when the operation
speed is different or when the travel
amount is small and the motor stops
immediately.
Change the sequence program as
needed so that the motor operation
using the FX -1PG becomes the
3U

FX -1PG by reducing the operation
