YASKAWA GA700 Series Technical Manual page 761

Note:
When A1-02 = 6 [Control Method Selection = AOLV/PM], the drive will automatically set F1-03 = 1 [Coast to Stop]. You cannot
change this value.

F1-04: Speed Deviation Detection Select
No.
Name
(Hex.)
F1-04 Speed Deviation Detection
Select
(0383)
When the difference between the frequency reference and the motor speed is more than the value set in F1-10
[Speed Deviation Detection Level] for longer than the time set in F1-11 [Speed Deviation Detect DelayTime], the
drive will detect dEv.
0 : Ramp to Stop
The drive ramps the motor to stop in the deceleration time. Fault relay output terminal MA-MC turns ON, and
MB-MC turns OFF.
1 : Coast to Stop
The output turns off and the motor coasts to stop. Fault relay output terminal MA-MC turns ON, and MB-MC
turns OFF.
2 : Fast Stop (Use C1-09)
The drive stops the motor in the deceleration time set in C1-09 [Fast Stop Time]. Fault relay output terminal MA-
MC turns ON, and MB-MC turns OFF.
3 : Alarm Only
The keypad shows dEv and the drive continues operation. Only use this setting in special conditions to prevent
damage to the motor and machinery. The output terminal set for Alarm [H2-01 to H2-03 = 10] activates.

F1-05: Encoder 1 Rotation Selection
No.
Name
(Hex.)
F1-05 Encoder 1 Rotation
Selection
(0384)
Refer to the option card installation manual for more information about how to set the encoder pulse output
sequence and make sure that it is correct.
0 : Pulse A leads in FWD Direction
1 : Pulse B leads in FWD Direction
■
F1-06: Encoder 1 Pulse Monitor Scaling
No.
Name
(Hex.)
F1-06 Encoder 1 Pulse Monitor
Scaling
(0385)
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.
Name
(Hex.)
F1-08 Overspeed Detection Level
(0387)
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.

V/f CL-V/f OLV CLV AOLV
Sets the method to stop the motor or let the motor continue operating when the drive detects dEv
[Speed Deviation].
V/f CL-V/f OLV CLV AOLV
Sets the output sequence for the A and B pulses from the encoder, assuming that the motor is
operating in the forward direction.
V/f CL-V/f OLV CLV AOLV
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.
V/f CL-V/f OLV CLV AOLV
Sets the detection level of oS [Overspeed] as a percentage when the maximum output frequency
is 100%.
