Axis Program Format Parameters
Chapter 16
16-4
Function
This parameter specifies whether trailing zero suppression mode is active
when a programmed word is decoded by the control. It should be disabled
when decimal point programming is being performed. When this
parameter is enabled, the control “left-justifies” the programmed word
according to the word format of the programmed word.
Leading zeros must be programmed to make sure that each word has its
required number of digits to the left and the right of the decimal point.
This number includes any suppressed trailing zeros.
For example, if this parameter is enabled and the X-axis word format is
4.3, then X01 is decoded as X0100.000 and X279 is decoded as
X2790.000.

mode cannot be enabled at the same time.
