Distinction between inching mode continuous mode

Continuous traversing in jog mode can be performed in jogging or in continuous traversing.
Continuous traversing in jog mode
In jog mode, the axis traverses as long as the traversing key is pressed. With the release of
the traversing key, the axis is decelerated to standstill. The movement is completed when
the parameterized exact stop criterion of the axis is reached.
If the axis reaches a traversing range limit before the traversing key is released (working
area limitation, software limit switch, etc.), the axis is stopped at the limit.
Continuous traversing in continuous mode
In continuous mode, traversing of the axis is started by pressing the traversing key. The
traversing movement is continued even after the traversing key is released.
Risk of collision
In continuous mode, several axes can be started by pressing the respective traversing key.
Any interlocks must be implemented by the user / machine manufacturer via the PLC user
program.
The traversing movement can be interrupted and continued by the operator at any time or
aborted. If the axis reaches a traversing range limit before canceling the traversing
movement (working area limitation, software limit switch, etc.), the axis is stopped at the
limit.
Interrupt traversing movement
The operator can interrupt traversing via the user interface of the machine control panel
(MCP) in the following ways:
● Feedrate override = 0%
● Feedrate stop
● NC stop or NC stop axis/spindle
If the cause of the interruption is removed, the axis continues to traverse.
