2.8 H: Terminal Functions
Note:
Refer to "b4: Timer Function" for more information.
■
19: PID Disable
Setting Value Function
19 PID Disable
ON : PID control disabled
OFF : PID control enabled
■
1A: Accel/Decel Time Selection 2
Setting Value Function
1A Accel/Decel Time Selection
2
Note:
Refer to "C1: Accel & Decel Time" for more information.
■
1B: Programming Lockout
Setting Value Function
1B Programming Lockout
You can continue to view parameter setting values when the terminal is OFF [Parameters Cannot be Edited].
ON : Program Lockout
OFF : Parameter Write Prohibit
■
1E: Reference Sample Hold
Setting Value Function
1E Reference Sample Hold
When the terminal is active for 100 ms, this function reads a sample of the analog frequency reference and holds that
sample. When you input the sample/hold command again, the function reads a sample of the analog frequency
reference again and holds that sample. When you turn off the power, the drive erases the saved analog frequency and
resets the frequency reference to 0.
Figure 2.83 shows an example of how the function operates.
You cannot set the Reference Sample Hold function at the same time as these functions:
• H1-xx = A [Accel/Decel Ramp Hold]
• H1-xx = 10, 11 [Up Command, Down Command]
• H1-xx = 44 to 46 [Offset Frequency 1 to 3]

V/f CL-V/f OLV CLV AOLV
Sets the command to disable PID control when b5-01 = 1 to 8 [PID Mode Setting = Enabled].
V/f CL-V/f OLV CLV AOLV
Set this function and H1-xx = 7[Accel/Decel Time Selection 1] together. Sets the drive to use Acceleration/Deceleration Time 3 [C1-
05, C1-06] or Acceleration/Deceleration Time 4 [C1-07, C1-08].
V/f CL-V/f OLV CLV AOLV
Sets the command to prevent parameter changes when the terminal is OFF.
V/f CL-V/f OLV CLV AOLV
Sets the command to sample the frequency reference at terminals A1, A2, or A3 and hold the frequency reference at that frequency.
