DISPLAY
Meaning

Display three digits after decimal point
Display two digits after decimal point
Display one digit after decimal point
No decimal point
The initial value will change depending on the
pulse frequency selection.
The decimal point can be optionally displayed.
When displaying the decimal point, consider the
number of digits to follow the decimal point prior to
setting the scaling display value.
If
p-fre
is set to 30, the initial setting for the
decimal display will be
000.00.
INPUT
Input value
Teaching with actual values is possible.
Instead of setting by inputting with the
Up Key and
Shift Key, current values can be
input as scaling input values for teaching. This is useful for making settings while checking the
operation status of the K3MA-F.
