32.3 How to Execute Multiple Tables
The execution method for multiple tables of the DRVTBL and DRVMUL instructions includes stepping operation and
continuous operation.
This section describes how to execute each operation.
Stepping operation
In stepping operation, with the DRVTBL instruction, specified tables are executed one by one. Only the DRVTBL instruction
can execute this operation.
Every time a table ends, the complete flag turns on and the next table is not automatically activated. After the table shift
command or external start signal is detected, the next table is executed. (Page 413 Table shift command, Page 398
External Start Signal)
The following figure shows an example of stepping operation with the tables 1 to 3 and dwell time.
*1 When the external start signal is enabled, the drive contact and external start signal must be turned on to activate the positioning
instruction.
*2 Remains on until the user turns off the flag or starts the next table.
