Motion Control in PR Mode Chapter 11
Procedure Section
This section uses the IF statement to determine whether the user-defined
condition is fulfilled. If it is true, jump to the specified PR command. If false,
jump to the other specified PR command. If you click Next PR in Quick Setting,
the software automatically inputs the condition and then jumps to the next PR
command. If you leave this section blank, then the PR procedure stops once the
basic operation is done. See Table 100
for data formats and operators.
Table 100 - Field Description for the Procedure Setting Section
Statement Section
This section includes statements and memory capacity. Statements save the data
from the expression and procedure sections. Data in the expression and
procedure sections of the same statement always remain identical and can be
shared by multiple PR commands. If data in those two sections are different, then
the data is saved to another statement. The time required to execute the
statement is shown in the Spend Time field. Total Capacity shows the servo
drive's memory capacity. Basic operations cannot be performed if there is no
memory space available.
The Statements tab is shown in Figure 117
. The upper section displays all the
statements and the lower section displays the operations in each statement and
the values.
