(2) Set the forward rotation and reverse
rotation individually.
[
Pr. 807
= 1,
Pr. 808, 809
]
Set the speed limit during forward rotation using [
Pr.
808 Forward rotation speed limit
] and the speed limit
during reverse rotation using [
Pr. 809 Reverse rotation
speed limit
].
The speed during forward and reverse rotation is
limited at the setting value of [
Pr. 808
] when [
Pr. 809
=
9999] (initial value).
The speed limit value changes according to
acceleration/deceleration time of [
Pr. 7, Pr. 8
].
(3) Forward rotation/reverse rotation speed
limit [
Pr. 807 = 2, C12 to C15(Pr. 917, 918), C30
to C33(Pr. 926, 927)
]
When making a speed limit using analog input to
terminal 1 or terminal 6 (FR-A7AZ), the speed limit of
the forward and reverse rotation can be switched
according to the polarity of voltage.
Forward/reverse rotation speed limit is valid when [
Pr.
868 Terminal 1 function assignment
= 5]. (Refer to page
for details of terminal1 function assignment)
Set [
Pr. 406 High resolution analog input selection
= 5] to
limit forward/reverse rotation speed using terminal 6
(FR-A7AZ). When [
Pr. 406
= 5] and [
Pr. 868
= 5],
terminal 6 is the forward/reverse speed limit, and
terminal 1 does not have a function.
Speed limit by analog terminal input can be calibrated
using calibration parameter [
C12
to
15
(
Pr. 917, Pr.
918
)], [
C34
to
37
(
Pr. 928, Pr. 929
)].
For 0 to 10V input, set the forward rotation speed
limit. The reverse rotation speed limit at this time is
the value of [
Pr. 1 Maximum frequency
]. The speed limit
value does not follow acceleration/deceleration time
of [
Pr. 7 and Pr. 8
].
For -10 to 0V input, set the reverse rotation speed
limit. The forward rotation speed limit at this time is
the value of [
Pr. 1 Maximum frequency
] .The forward
rotation speed limit does not follow acceleration/
deceleration time of [
Pr. 7, Pr. 8
].
The maximum speed of both the forward and reverse
rotations is [
Pr. 1Maximum frequency
].
