Table A.1 F7 Parameter List (Continued)
Description
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.
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.
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.
Sets the gear ratio between the motor shaft and the encoder (PG).
Input pulses from PG (PPR) x 60
F1-01
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.
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.
Sets the number of pulses for the encoder (pulse generator) for each
full rotation of Motor 2.
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.)
Sets the number of gear teeth (deceleration ratio) between Motor 2
and the pulse generator.
Input pulses from PG (PPR) x 60
PG Constant (F1-21)
A gear ratio of 1 will be used if either of these constants is set to 0.
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.
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
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.
