z Relation between the wrap function and the 32-bit counter inside the driver
The 32-bit counter inside the driver outputs the position information of the motor as the number of steps regardless
of whether the wrap function is enabled or disabled.
When the wrap function is enabled, the relation between the wrap coordinate and the 32-bit counter is shown below.
Example:
If the wrap function is activated when the motor rotates by 180 revolutions in the same direction.
Motor output shaft
0 to 180 revolutions
180 rev
Wrap coordinate
(rev)
The present position of the motor is preset by 180 revolutions, however, the 32-bit counter is not preset.
The value of the 32-bit counter can be checked using the following methods.
• Status monitor window of MEXE02 software
• Monitor command of EtherNet/IP
The 32-bit counter goes around between −2,147,483,648 and 2,147,483,647.
It shows 2,147,483,647 after –2,147,483,648,
and after that, it shows in descending order.
