1B: Program Lockout
Setting Function

The user can still 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 Function
1E Reference sample
hold
This function takes a sample of the analog frequency reference at the point in time 100 ms has passed since the
terminal was turned ON, and holds the sample. If the sample/hold command is re-input, the function takes another
sample of the analog frequency reference and holds it. If the power is shut off, the analog frequency that was
saved via sampling will be erased and the frequency reference will be reset to 0.
The following illustration shows an example of how the function operates.
The Reference sample hold function cannot be set at the same time as the following functions. Setting them at the
same time will trigger oPE03 [Multi-Function Input Setting Err].
• H1-xx = A [Accel/Decel Ramp Hold]
• H1-xx = 10, 11 [Up Command, Down Command]
• H1-xx = 44 to 46 [Offset frequency]
• H1-xx = 75, 76 [Up 2 Command, Down 2 Command]

V/f CL-V/f OLV CLV AOLV
Disables PID control using an external input when b5-01 = 1 to 8 [PID Function Setting =
Enabled].
V/f CL-V/f OLV CLV AOLV
It is used in combination with the Accel/decel Time Selection 1 [H1-xx = 7]. Switches between C1-
01 to C1-08 [Acceleration and Deceleration Times 1 to 4].
V/f CL-V/f OLV CLV AOLV
The following parameter setting values can be changed when the terminal set for program lockout
is ON. When the terminal is OFF, the setting values of parameters cannot be changed.
V/f CL-V/f OLV CLV AOLV
The analog frequency reference input via terminal A1, A2 or A3 will be sampled and operation will
continue at that frequency.
