64 Operation Theory
4.2.13 Simultaneous Start Function
Simultaneous motion means more than one axis can be started by
a Simultaneous signal which could be external or internal signals.
For external signal, users must set move parameters first for all
axes then these axes will wait an extern start/stop command to
start or stop. For internal signal, the start command could be from
a software start function. Once it is issued, all axes which are in
waiting synchronous mode will start at the same time.
4.2.14 Speed Override Function
Speed override means that users can change command’s speed
during the operation of motion. The change parameter is a per-
centage of original defined speed. Users can define a 100% speed
value then change the speed by percentage of original speed
when motion is running. If users didn’t define the 100% speed
value. The default 100% speed is the latest motion command’s
maximum speed. This function can be applied on any motion func-
tion. If the running motion is S-curve or bell curve, the speed over-
ride will be a pure s-curve. If the running motion is t-curve, the
speed override will be a t-curve.
