6-1 Overview of direct data operation
Direct data operation is a mode that allows rewriting of data and start of operation to be executed at the same time.
It is suitable to frequently change operation data such as the position (travel amount) and speed or to fine-tune the
position.
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, speed, starting/changing speed rate, stopping deceleration,
and operating current
• The above six items are collectively rewritten
The 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 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
• Speed: Change as desired
• TRIG-MODE: Start at ON edge of TRIG

Operation processing flow
Descriptions are given using the host controller as the
subject.
1. Write the position and the speed.
2. Turn the TRIG ON.

Result
When the TRIG is turned ON, the changed value is updated
immediately, and operation is performed with the new
position and speed.
