Infinite position mode
8.4
Overview
8.4.1
The infinite position mode function can be used in scenarios where the device is required to run continuously in a single
direction to ensure that the device can continue to run normally when the travel exceeds the target position value limit or the
motor encoder multi-turn value limit, such as the conveyor belt, turntable, and so on.

There are three setting methods for the [infinite position mode] function: setting [normal infinite position control mode]
only, simultaneously setting [normal infinite position control mode] + [Encoder Multi-Turn Upper Limit Value], and
simultaneously setting [modulo infinite position control mode] + [Encoder Multi-Turn Upper Limit Value]. The differences of the
three methods are as follows:
Normal infinite position mode
This method is suitable for scenarios where the device only needs to run continuously in a single direction and the
operating positions in a single cycle do not need to be known.
When using this method, the set value of the [Encoder Multi-Turn Upper Limit Value] must be 0. The target position value
limit given by the upper computer is limited by the data length of the object "0x607A: Target Position", i.e. -2

-1 Inc. When
the target position value increases progressively and exceeds the upper limit, it is automatically reset to the lower limit and
increments are counted again. Or, when the target position value decreases progressively and is less than the lower limit, it is
automatically reset to the upper limit and decrements are counted again.
Normal infinite position control mode + Encoder Multi-Turn Upper Limit Value
This method is suitable for scenarios where the device needs to run continuously in a single direction and the operating
positions in a single cycle need to be known. Besides, because of the use of absolute multi-turn encoder, it is also possible to
know the current position after restart without returning to the origin.
