Figure 4.37 Analog Frequency Reference Sample/Hold
An oPE03 error will occur when one of the following functions is used simultaneously with the Analog frequency reference
sample/hold command:
• Hold accel/decel stop (setting: A)
• Up command, Down command (setting: 10, 11)
• Up or Down functions (setting: 75, 76)
Settings 20 to 2F: External Fault
The External fault command stops the drive when problems occur with external devices.
To use the External fault command, set one of the multi-function digital inputs to a value between 20 and 2F. The digital
operator will display EFo where o is the number of the terminal 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
An “On-Delay” timer will be applied to the external fault if it is “Normally Open” and an “Off-Delay” timer will be applied
to the external fault if it is “Normally Closed”.
If the external fault is set to “During Run”, the time delay will start after the Run command is received.

shows the relationship between the conditions and the value set to H1-oo:
Terminal statuses, detection conditions, and stopping methods marked with an “O” are applicable to the corresponding settings.
