YASKAWA SIEPC71061737D GA800 Drive Technical Reference 845
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
■ F1-33: Encoder 2 Gear Teeth 1
No.
(Hex.)
Name Description
Default
(Range)
F1-33
(03B2)
Encoder 2 Gear Teeth 1
Sets the number of gear teeth on the motor side for motor 2. This parameter and F1-34 [Encoder 2
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:
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
