Description
0: Phase A leads with Forward
Run Command. (Phase B
leads with Reverse Run
Command.)
1: Phase B leads with Forward
Run Command. (Phase A
leads with Reverse Run
Command.)
Sets the division ratio for the PG
speed control board pulse out-
put.
Division ratio = (1+ n) /m (n=0
or 1 m=1 to 32)
F1-06
n
m
This constant is only effective
when a PG-B2 is used.
The possible division ratio set-
tings are: 1/32 ≤ F1-06 ≤ 1.
Sets integral control during
acceleration/deceleration to
either enabled or disabled.
0: Disabled (The integral
function isn't used while
accelerating or decelerating;
it is used at constant speeds.)
1: Enabled (The integral
function is used at all times.)
Sets the overspeed detection
method.
Frequencies above that set for
F1-08 (set as a percentage of the
maximum output frequency)
that continue to exceed this fre-
quency for the time set in F1-09
are detected as overspeed faults.
Sets the speed deviation detec-
tion method.
Any speed deviation above the
F1-10 set level (set as a percent-
age of the maximum output fre-
quency) that continues for the
time set in F1-11 is detected as a
speed deviation.
Speed deviation is the difference
between actual motor speed and
the reference command speed.
Sets the number of teeth on the
gears if there are gears between
the PG and the motor.
Input pulses from PG 60
F1-01
A gear ratio of 1 will be used if
either of these constants is set to
0.
Used to set the PG disconnec-
tion detection time. PGO will be
detected if the detection time
continues beyond the set time.
