Setting Precautions
When using sample/hold of analog frequency reference, you cannot use the following commands at the same
time. Otherwise operation fault OPE03 (invalid multi-function input selection) will occur.
• Acceleration/Deceleration Ramp Hold command
• UP/DOWN command
• Trim Control Increase/Decrease command
Application Precautions
• When performing sample/hold of analog frequency reference, be sure to close the digital input for 100 ms
or more. If the sample/hold time is less than 100 ms, the frequency reference will not be held.
• The frequency reference value that is held will be deleted when the power supply is turned OFF.
îš‹ Switching Operation Source to Communication Option Card
The source of frequency reference and RUN command can be switched between a Communication option
card and the sources selected in b1-01 and b1-02. Set one of the parameters H1-01 to H1-05 (digital inputs S3
to S7 function selection) to 2 to enable operation source switch over.
If a RUN command is active, the switch over will not be accepted.

îš„Setting Precautions
To use the operation source switching function make the following settings:
• Set b1-01 (frequency reference source) to a value different from 3 (option card).
• Set b1-02 (RUN command source) to a value different from 3 (option card).
• Set one of the parameters H1-01 to H1-05 to 2.
îš‹ Jog Frequency with Direction Commands (FJOG/RJOG)
The FJOG/RJOG function operates the inverter at the jog frequency. It can be activated by using the terminal
ON/OFF operation. When using the FJOG/RJOG commands, there is no need to input the RUN command.
To use this function, set one of the parameters H1-01 to H1-05 (terminal S3 to S7 function selection) to 12
(FJOG command) or 13 (RJOG command).
