Overview of direct data operation
Direct data operation is a mode that allows start of operation at the same time as rewriting of data.
It is suitable to frequently change operation data such as the position (travel amount) or the operating speed, or to
applications to adjust the position finely.
There are the following seven types of triggers to start operation at the same time as rewriting of data.
•
One of the following items: Operation type, position, operating speed, starting/changing speed rate, stopping
deceleration, and operating current
•
The above six items are collectively rewritten
Direct data operation is executed with the TRIG of fixed I/O (IN).
A condition to execute direct data operation can be selected from the following two types using the TRIG-MODE of
fixed I/O (IN).
•
Start at ON edge of TRIG: The motor will start according to the operation data being set when the TRIG is turned
ON.
•
Start at ON level of TRIG: The motor will start at the same time when the data of the trigger set in the “Direct data
operation trigger setting” parameter is changed.
Application example 1 of direct data operation
The position (travel amount) or the operating speed should
be adjusted each time a load is changed because the feed
rate is different in each load.
z
Setting example
•
Position (travel amount): Change as desired
•
Operating speed: Change as desired
•
TRIG-MODE: Start at ON edge of TRIG
z
Operation processing flow
Descriptions are given using the scanner as the subject.
1. Write the position and the operating speed.
2. Turn the TRIG ON.
z
Result
When the TRIG is turned ON, the changed value is updated
immediately, and operation is performed with the new
position and operating speed.
