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 1 shows an example of how the function operates.
Figure 1. 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]
-
H1-xx = 75, 76 [Up 2 Command, Down 2 Command]
If you set them at the same time, the drive will detect oPE03 [Multi-Function Input Setting Err].
