12.8 H: Terminal Functions
894 YASKAWA SIEPC71061737D GA800 Drive Technical Reference
Note:
Refer to “b4: Timer Function” for more information.
■ 19: PID Disable
Setting Value Function Description
19 PID Disable
Sets the command to disable PID control when b5-01 = 1 to 8 [PID Mode Setting = Enabled].
ON : PID control disabled
OFF : PID control enabled
■ 1A: Accel/Decel Time Selection 2
Setting Value Function Description
1A Accel/Decel Time Selection
2
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].
Note:
Refer to C1: Accel & Decel Time on page 769 for more information.
■ 1B: Programming Lockout
Setting Value Function Description
1B Programming Lockout
Sets the command to prevent parameter changes when the terminal is OFF.
You can continue to view parameter setting values when the terminal is OFF [Parameter Write Prohibit].
ON : Programming Lockout
OFF : Parameter Write Prohibit
■ 1E: Reference Sample Hold
Setting Value Function Description
1E Reference Sample Hold
Sets the command to sample the frequency reference at terminals A1, A2, or A3 and hold the frequency reference at that frequency.
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 12.83 shows an example of how the function operates.
Figure 12.83 Reference Sample Hold
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]
