Axis Program Format Parameters
Chapter 16
16-3
The zero suppression mode parameters are covered in the following
sections:
Parameter: Page:
Leading Zero Suppression Mode 16-3
Trailing Zero Suppression Mode 16-4
Error if Letter Numeric Missing 16-5
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.

mode cannot be enabled at the same time.
