12.4
Speed/Position Expansion Function Setting
The speed/position expansion function uses a 24-bit encoder to perform optimum positioning.
To do so, the setting ranges are expanded for speed parameters, position parameters, and
serial command data.
This function is supported for INDEXER Modules with software version 0007 or higher.
If you set PnB54 to 1 (Enable Expansion Mode), the setting ranges for parameters, serial com-
mands, and program tables, the number of display digits for monitor commands, and the num-
ber of display digits on the Digital Operator will be expanded. Details are provided below.
