5 SERVO PROGRAMS FOR POSITIONING CONTROL
5.4 Setting Method for Positioning Data
This section describes how to set the positioning data used in the servo program.
There are two ways to set positioning data, as follows:
(1) Setting by specifying numerical values … Refer to Section 5.4.1
(2) Indirect setting by devices ……….… Refer to Section 5.4.2
"Setting by specifying numerical values" and "indirect setting by word devices" can be used together in one servo program.
5.4.1 Setting method by specifying numerical values
In the setting method by specifying numerical values, each positioning data is set by a numerical value, and it becomes fixed data.
Data can be set and corrected using MT Developer only.
