Fig. 5-37 Traverse operation
The central frequency is actually the preset frequency of simple operation (except PLC, traverse operation, jog),
multi-step speed operation or PLC operations;
Traverse operating function is disabled automatically in Jog operation or close-loop operation process.
If PLC operation and traverse operation start at the same time, the traverse operation is disabled when the drive transits
from one PLC operating stage to another stage. The drive will accelerate to the preset frequency of PLC operation and
then start traverse operation. The drive will decelerate to stop within the Dec time set in PLC operating stage.
