Setting 1E: Analog Frequency Reference Sample / Hold
This function allows the user to sample an analog signal being input to A1, A2, or A3 and change the frequency reference to the sampled level. Once the
digital input that is configured for the Analog Frequency Reference Sample / Hold function is held for at least 100 ms, the drive reads the analog input
and changes the frequency reference to the newly sampled speed.
• The following functions cannot be programmed to a multi-function input terminal the same time as the Analog Frequency Reference Sample / Hold
function. Doing so will cause an oPE03 error.
♦ Hold Accel/Decel Stop (setting: A)
♦ Up command, Down command (setting: 10, 11)
♦ Offset Frequency (setting: 44 to 46)
♦ Up or Down functions (setting: 75, 76)
• The analog frequency reference that has been sampled by this function will be cleared if the power is shut off.
• When the power is shut off and the sampled analog frequency reference is cleared, the frequency reference is reset to 0.
• Remember that the digital input must be held for at least 100 ms. If the digital input is not held for at least 100 ms, the analog input will not be sampled.
Setting 20 to 2F: External Fault
By using the External Fault function, the drive can be stopped when problems occur with external devices.
To use the external fault function, set one of the multi-function digital inputs to any value between 20 to 2F. The operator will display EFo where o is
the number of the terminal (terminal So) to which the external fault signal is assigned.
For example, if an external fault signal is input to terminal S3, "EF3" will be displayed.
Select the value to be set in H1-01 to H1-06 from a combination of any of the following three conditions:
• Signal input level from peripheral devices
• External fault detection method
• Operation after external fault detection
The table below shows the relationship between the conditions and the value set to H1-oo:

*1. Determine the terminal status for each fault: whether the terminal is normally open or normally closed.
*2. Determine whether detection for each fault should be enabled only during run or always detected.
• Always Detected: Detection enabled as soon as the drive is powered up
• Detection during Run: Detection enabled only during run.
