YASKAWA SIEPC71061723A YASKAWA AC Drive CR700 Technical Manual 653
The drive detects dEv when the difference (speed deviation) between the frequency reference and the actual motor
speed exceeds the value set in F1-10 [Speed Deviation Detection Level] for an amount of time longer than the
time set in
F1-11 [Speed Deviation Detect DelayTime]
.
0 : Ramp to Stop
The drive ramps the motor to stop according to the deceleration time. Fault relay output terminal MA-MC will
turn ON, and MB-MC will turn OFF.
1 : Coast to Stop
The drive output shuts off and the motor coasts to stop. Fault relay output terminal MA-MC will turn ON, and
MB-MC will turn OFF.
2 : Fast Stop (Use C1-09)
The drive stops the motor using the deceleration time set in C1-09 [Fast Stop Time] . Fault relay output terminal
MA-MC will turn ON, and MB-MC will turn OFF.
3 : Alarm Only
The keypad shows dEv , and the drive continues operation. Due to potential damage to motor and machinery,
refrain from using this setting except under special circumstances. The output terminal set for Alarm [H2-01 to
H2-05 = 10]
switches ON.

F1-05: Encoder 1 Rotation Selection
No.
(Hex.)
Name Description
Default
(Range)
F1-05
(0384)
Encoder 1 Rotation
Selection
Sets the output sequence for the A and B pulses from the encoder, assuming that the motor is
operating in the forward direction.
Determined by A1-02
(0, 1)
Refer to the installation manual included with the option card for more information on how to confirm and set the
encoder pulse output sequence.
0 : Pulse A leads in FWD Direction
1 : Pulse B leads in FWD Direction
■
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 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 .
