Adjust the inclination with [Cd-24]. Change [Cd-24] to make an adjustment immediately before
the point at which [Ao2] begins lowering from 20 mA.
(For example, see and wait with a range from 75.0 to 85.0%.)
[Cd-23]=20.0%, [Cd-24]=80.0%

Returning [Cd-10] to 00 starts current output of [Ao1] that is adjusted.
With the FM output function, you can make selections from the PWM output in which a duty ratio
changes and the digital frequency output in which a frequency changes.
Precautions for Correct Use
• The finally determined output does not exceed an output range of the [FM] output terminal.
• When [Cd-10]=01 is set, [FM], [Ao1], and [Ao2] respectively perform outputs in accordance
with the values of [Cd-15], [Cd-25], and [Cd-35].
