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.

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]
