Speed Deviation Detect
DelayTime
Sets the length of time that the difference between the frequency reference and speed
feedback must be more than the level in F1-10 to cause dEv [Speed Deviation].
Note:
If A1-02 = 0 [Control Method Selection = V/f], you must set H6-01 = 3 [Terminal
RP Pulse Train Function = Speed Feedback (V/F Control)] to enable this
parameter.

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

Encoder 2 Gear Teeth 1
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.

Encoder Open-Circuit
Detect Time
Sets the length of time that the drive must not receive a pulse signal to cause PGo
[Encoder (PG) Feedback Loss].
Note:
Motor speed and load conditions can cause ov [Overvoltage] and oC [Overcurrent]
faults.
If A1-02 = 0 [Control Method Selection = V/f], you must set H6-01 = 3 [Terminal
RP Pulse Train Function = Speed Feedback (V/F Control)] to enable this
parameter.

Deviation 2 Detection
Selection
Usually it is not necessary to change this setting. Sets the number of motor rotations that
the drive will detect more than one Z pulse per rotation to detect dv2.

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.

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).
