*F_35 0.00 GAIN FOR FREQUENCY SETTING SIGNAL
to This sets the size (gradient) of the output frequency
250 corresponding to the analog frequency setting as a
percentage of the maximum frequency.
[Example: for 70% gain]
*The gain setting is only active when F_01 = 1
Example:
If the bias frequency function (F_34) and the gain for
frequency setting signal function (F_35) are used together,
the gain for frequency setting signal has priority, and the
bias is applied to the frequency with gain already applied.
The bias frequency f

Example:
If the analog frequency setting voltage is 1 to 5Vdc
and the output frequency is weighted to 0 to 100% then:

*F_36 0 to 400 HIGH FREQUENCY LIMITER
*F_37 0 to 400 LOW FREQUENCY LIMITER
The high and low limits for the output frequency can be
set within a range of 0 to 400Hz in stages of 1Hz.
NOTE:
If the high and low limit settings are reversed, the high
limit has priority and the low limit is ignored.
*F_38 0 to 10 MOTOR CHARACTERISTICS
This adjusts the output current in cases where there is
an irregularity such as current fluctuation. If a current
fluctuation occurs, adjust the setting value while
referring to the tables below.

F_39 DATA INITIALIZATION
This resets all Function Codes to factory settings.
0: Inactive (manual setting)
1: Initial values (Initialization with factory defaults)
[Operation Procedure]
When 0 is being displayed, press the STOP +
keys simultaneously to change the display to 1.
In this condition, press the
all data to the factory default settings. The display
will then automatically switch to show the frequency
setting for STOP mode.
