5.7 H: Terminal Functions
Referenece Referenece
Sample Hold Input Sample Hold Input
An oPE03 error will occur when one of the following functions is used simultaneously with the Analog Frequency
Reference Sample/Hold function.
• 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)
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-oo from a combination of any of the following three conditions:
• Signal input level from peripheral devices (N.O./N.C.)
• External fault detection method
• Operation after external fault detection
The following table shows the relationship between the conditions and the value set to H1-oo:

<1> Determine the terminal status for each fault, i.e., 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.
Setting 30: PID Integral Reset
By configuring one of the digital inputs as an Integral Reset Input, (H1-oo = 30), the value of the integral component of
PID control can be reset to 0 whenever the configured input is closed. The integral component of PID control will be held
at 0 as long as the configured digital input is held closed.
