5.3.4 Setting output frequency
This sets the AC voltage frequency.
When either AC-SYNC or AC+DC-SYNC mode is selected, the AC voltage frequency cannot be set.

See “3.4.7 Using limiter functions”
, when using a setting range limit for output frequency.
Operation steps
To set the output frequency, set a numerical value labeled in the SET menu.
See “3.4.6 Setting output frequency” , for description of output frequency settings.
See “5.5.5 Setting range limiter (LIMIT)”
, for description of setting range limits.

CAUTION
-------------------------------------------------------------------------------------------------
If the frequency is set under 40 Hz in AC-INT mode, there is a possibility that the output
waveform will be distorted and DC offset will be output.

5.3.5 Output initial phase settings
When AC-INT, AC-ADD, AC-SYNC, AC+DC-INT, AC+DC-ADD, or AC+DC-SYNC mode is selected,
the AC voltage phase can be set according to the internal signal source when output is on.
