F1-13
(038C)
Encoder 1 Gear
Teeth 2
Sets the number of gear teeth on the load side. This parameter and
F1-12 [Encoder 1 Gear Teeth 1] set the gear ratio between the
motor and encoder.

F1-14
(038D)
Encoder Open-
Circuit Detect
Time
Sets the length of time that the drive must not receive a pulse signal
to cause a PGo [Encoder (PG) Feedback Loss].
Note:
Motor speed and load conditions can cause ov [Overvoltage] and
oC [Overcurrent] faults.
2.0 s
(0.0 - 10.0 s)

F1-18
(03AD)
Deviation 3
Detection Selection
Sets the number of rotations necessary to detect conditions that
invert the torque reference and rate of acceleration and cause dv3
[Inversion Detection].

Encoder 1 PCB
Disconnect Detect
Sets the function that enables and disables detection of a
disconnected encoder connection cable to cause PGoH [Encoder
(PG) Hardware Fault].

Encoder 2 Pulse
Count (PPR)
Sets the number of output pulses for each motor revolution for
motor 2.
1024 ppr
(1 - 60000 ppr)
825
F1-32
(03B1)
Encoder 2 Rotation
Selection
Sets the output sequence for the A and B pulses from the encoder
for motor 2. This parameter assumes that the motor is operating in
the forward direction.
0 : Pulse A leads in FWD Direction
1 : Pulse B leads in FWD Direction

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)

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)

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.
The dividing ratio = (1 + x)/yz when the setting value is a 3-digit
value (xyz).
