Parameters A - 19
F1-07
Integral Function During
Accel/Decel Selection
PG Ramp PI/I Sel
Sets integral control during acceleration/deceleration to either
enabled or disabled.
0: Disabled - The integral function is not used while accelerating
or decelerating.
1: Enabled - The integral function is used at all times.
0 to 1 0 - A - -
F1-08
Overspeed Detection Level
PG Overspd Level
Configures the overspeed fault (OS) detection.
OS fault will occur, if the motor speed feedback is greater than the
F1-08 setting for a time longer than F1-09. F1-08 is set as a
percentage of the maximum output frequency (E1-04). See F1-03. 0 to 120 115% - A - A

Excessive Speed
Deviation Detection Level
PG Deviate Level Configures the speed deviation fault (DEV) detection.
DEV fault will occur if the speed deviation is greater than the
F1-10 setting for a time longer than F1-11. F1-10 is set as a
percentage of the maximum output frequency (E1-04).
Speed deviation is the difference between actual motor speed and
the frequency reference command. See F1-04.

Number of PG
Gear Teeth 1
PG # Gear Teeth1 Sets the gear ratio between the motor shaft and the encoder (PG).
A gear ratio of 1 will be used if either of these parameters is set to 0.
This function is not available in flux vector control.

PG Open-Circuit
Detection Time
PGO Detect Time
Configures the PG open (PGO) function. PGO will be detected if no
PG pulses are detected for a time longer than F1-14. See F1-02. 0.0 to

PG Rotation 2
PG Rotation Sel2
Determines the direction of rotation for the encoder (PG) connected
to Motor 2.
0: Phase A leads with Forward Run Command.
(Phase B leads with Reverse Run Command.)
1: Phase B leads with Forward Run Command.
(Phase A leads with Reverse Run Command.)
0, 1 0 No Q No Q
F1-23
<3021>
Number of PG
Gear Teeth 1
PG Gear Teeth1 Sets the number of gear teeth (deceleration ratio) between Motor 2
and the pulse generator.
A gear ratio of 1 will be used if either of these constants is set to 0.

Hardware Disconnect
Detection Selection CH 1
Hardware PGO ch1
Enables or disables the drive from detecting when the PG option on
CH1 has been disconnected.
0: Disabled
1: Enabled
Enabled when using PG-T2 or Z2.

Hardware Disconnect
Detection Selection CH 2
Hardware PGO ch2
Enables or disables the drive from detecting when the PG option on
CH2 has been disconnected.
0: Disabled
1: Enabled
Enabled when using PG-Z2.

AI-14 Setup
F2-01
AI-14 Input Selection
AI-14 Input Sel
Sets the function for channel 1 to 3 of the AI-14B analog input
reference option board.
0: 3-channel individual (Channel 1: terminal A1, Channel 2:
terminal A2, Channel 3: terminal A3)
1: 3-channel addition (Summed values of channels 1 to 3 is the
frequency reference)
When set to 0, select 1 for b1-01. In this case, the multi-function
input “Option/Inverter selection” cannot be used.
0 to 1 0 A A A A
Denotes that parameter can be changed when the Drive is running.
* Enabled when an option card is connected to the PG encoder 2CH input (F1-21 to F1-24).
