1E: Reference Sample Hold
Setting Value Function Description
1E Reference Sample Hold
Samples the analog frequency reference input to the terminals A1, A2, or A3, and continues operation at the sampled frequency.
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.
Figure 11.55 Reference Sample Hold
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 or 11 [Up Command or Down Command]
•
H1-xx = 44 to 46 [Offset frequency]

20 to 2F: External Fault
Setting Value Function Description
20 to 2F External Fault
Sets a command to stop the drive when a failure or fault occurs on an external device.
If an external fault is input to the drive, the keypad will show EFx [External Fault (Terminal Sx)] , where x is the
number of the terminal (terminal Sx) to which the external fault signal is assigned. For example, when an external
fault signal is input to terminal S3, the keypad will show EF3.
Use these conditions to select the value to set in
H1-xx :
• Signal input method from peripheral devices
• External fault detection method
• Motor stopping method (operation after external fault detection)
Table 11.28 shows the relation between the conditions and the value set to H1-xx .
