Function
This parameter specifies whether leading 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 “right-justifies” the programmed word
according to the word format of the programmed word.
Trailing 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 leading zeros.
For example, if this parameter is enabled and the X-axis word format is
4.3, then X01 is decoded as X0000.001 and X2790 is decoded as
X0002.790.

This is a global parameter; the value set here applies to all axes and processes.
Important: Leading zero suppression mode and trailing zero suppression
mode cannot be enabled at the same time.
