Perform the preset function by applying an ON voltage to the preset input terminal for external input.

While CH External preset request detection (X4, XB) is on (3)), the preset function cannot be performed even if a voltage 
is applied to the preset input terminal or CH Preset command (Y1, Y9) is turned on.
The preset function can be performed when CH External preset request detection (X4, XB) is turned off by turning on CH 
External preset detection reset command (Y5, YD) (4)).

1)

Write a value to CH Preset value (Un\G0, Un\G1, Un\G32, Un\G33) in 32-bit signed binary.

2)

On the rising edge (off to on) of the preset command (A voltage is applied to the preset input terminal.), the value 
stored in CH Present value (Un\G2, Un\G3, Un\G34, Un\G35) is replaced with the value stored in CH Preset 
value (Un\G0, Un\G1, Un\G32, Un\G33).
The preset function is performed regardless of the on/off status of CH Count enable command (Y4, YC).
