0: Fwd=C.C.W. - Phase A leads
with forward run command.
(Phase B leads with reverse run
command.)
1: Fwd=C.W. - Phase B leads
with forward run command.
(Phase A leads with reverse
run command.)
Sets the division ratio for the pulse
monitor of the PG-B2 encoder
feedback option board. This func-
tion is not available with the PG-
X2 option board.
Division ratio = [(1 + n) / m]
(n = 0 to 1, m =1 to 32)
The first digit of the value of
F1-06 stands for n, the second and
the third stand for m. (from left to
right).
The possible division ratio
settings are:
1/32 ≤ F1-06 ≤ 1
Sets integral control during
acceleration/deceleration to either
enabled or disabled.
0: Disabled - The integral
function is not used while
accelerating or decelerating.
1: Enabled - The integral function
is used at all times.
Configures the overspeed fault
(OS) detection.
OS fault will occur, if the motor
speed feedback is greater than the
F1-08 setting for a time longer
than F1-09. F1-08 is set as a
percentage of the maximum output
frequency (E1-04). See F1-03.
Configures the speed deviation
fault (DEV) detection.
DEV fault will occur if the speed
deviation is greater than the F1-10
setting for a time longer than
F1-11. F1-10 is set as a
percentage of the maximum
output frequency (E1-04). Speed
deviation is the difference between
actual motor speed and the fre-
quency reference
command. See F1-04.
