F1-06: Encoder 1 Pulse Monitor Scaling
No.
(Hex.)
Name
Description
Default
(Range)
F1-06
(0385)
Encoder 1 Pulse
Monitor Scaling
Sets the ratio between the pulse input and the pulse output of the encoder as
a 3-digit number. The first digit is the numerator and the second and third
digits set the denominator.
001
(001 - 032, 102 - 132
(1 - 1/32))
When the setting value is a 3-digit value (xyz), the dividing ratio is (1 + x)/yz
For example, when
F1-06 = 032
, the dividing ratio is 1/32.
Note:
When you use a single-pulse encoder, the dividing ratio for the monitor signal is 1:1
F1-08: Overspeed Detection Level
No.
(Hex.)
Name
Description
Default
(Range)
F1-08
(0387)
Overspeed Detection
Level
Sets the detection level of
oS [Overspeed]
as a percentage when the
maximum output frequency is 100%.
115%
(0 - 120%)
When the motor speed is more than the value set in
F1-08
for longer than the time set in
F1-09 [Overspeed
Detection Delay Time]
, the drive will detect
oS
.
F1-09: Overspeed Detection Delay Time
No.
(Hex.)
Name
Description
Default
(Range)
F1-09
(0388)
Overspeed Detection
Delay Time
Sets the length of time that the speed feedback must be more than the
F1-08
level to cause an
oS [Overspeed]
.
Determined by A1-02
(0.0 - 2.0 s)
When the motor speed is more than the value set in
F1-08 [Overspeed Detection Level]
for longer than the time
set in
F1-09
, the drive will detect
oS
.
F1-10: Speed Deviation Detection Level
No.
(Hex.)
Name
Description
Default
(Range)
F1-10
(0389)
Speed Deviation
Detection Level
Sets the detection level of
dEv [Speed Deviation]
as a percentage when the
maximum output frequency is 100%.
10%
(0 - 50%)
When the speed deviation between the frequency reference and the actual motor speed is more than the value set
in
F1-10
for longer than the time set in
F1-11 [Speed Deviation Detect DelayTime]
, the drive will detect
dEv
.
F1-11: Speed Deviation Detect DelayTime
No.
(Hex.)
Name
Description
Default
(Range)
F1-11
(038A)
Speed Deviation
Detect DelayTime
Sets the length of time that the difference between the frequency reference
and speed feedback must be more than the level in
F1-10
to cause a
dEv
[Speed Deviation]
.
0.5 s
(0.0 - 10.0 s)
When the speed deviation between the frequency reference and the actual motor speed is more than the value set
in
F1-10 [Speed Deviation Detection Level]
for longer than the time set in
F1-11
, the drive will detect
dEv
.
F1-12: Encoder 1 Gear Teeth 1
No.
(Hex.)
Name
Description
Default
(Range)
F1-12
(038B)
Encoder 1 Gear Teeth
1
Sets the number of gear teeth on the motor side. This parameter and
F1-13
[Encoder 1 Gear Teeth 2]
set the gear ratio between the motor and encoder.
0
(0 - 1000)
After you set the number of gear teeth, the drive uses this formula to calculate the motor speed:
