826 YASKAWA ELECTRIC SIEP C710617 05F YASKAWA AC Drive GA700 Technical Manual
After you set the number of gear teeth, the drive uses this formula to calculate the motor speed:
Note:
When F1-33 = 0 or F1-34 = 0, the gear ratio is 1.
■ F1-34: Encoder 2 Gear Teeth 2
No.
(Hex.)
Name Description
Default
(Range)
F1-34
(03B3)
Encoder 2 Gear Teeth
2
Sets the number of gear teeth on the load side for motor 2. This parameter
and F1-33 [Encoder 2 Gear Teeth 1] 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:
Note:
When F1-33 = 0 or F1-34 = 0, the gear ratio is 1.
■ F1-35: Encoder 2 Pulse Monitor Scaling
No.
(Hex.)
Name Description
Default
(Range)
F1-35
(03BE)
Encoder 2 Pulse
Monitor Scaling
Sets the ratio between the pulse input and the pulse output of the encoder as
a 3-digit number for motor 2. 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 F1-35 = 032, the dividing ratio is 1/32.
Note:
For a single-pulse encoder, the dividing ratio for the monitor signal is 1:1.
■ F1-36: Encoder 2 PCB Disconnect Detect
No.
(Hex.)
Name Description
Default
(Range)
F1-36
(03B5)
Encoder 2 PCB
Disconnect Detect
Sets the function that enables and disables detection of a disconnected
encoder connection cable to cause PGoH [Encoder (PG) Hardware Fault]
for motor 2.
1
(0, 1)
0 : Disabled
1 : Enabled
■ F1-37: Encoder 2 Signal Selection
No.
(Hex.)
Name Description
Default
(Range)
F1-37
(03BD)
Encoder 2 Signal
Selection
Sets the number of channels for the signal to the encoder option card for
motor 2.
0
(0, 1)
0 : A Pulse Detection
1 : AB Pulse Detection
