6.3.3. Function to Limit Acceleration / Deceleration
l
You may set limitation of steep changes in acceleration and deceleration induced by changes of
velocity commands.
l
The parameter AL sets the limitation of acceleration and deceleration.
l
If a command of acceleration or deceleration exceeds the setting of parameter AL, the
acceleration and deceleration will be limited to AL [ s
-2
].

Set AL limitation
No limitationas as acceleration is less
than AL.

PLS velocity
Velocity command
However, the function of limiting acceleration /deceleration is not valid in the following cases.
à
When the Motor is stopping due to the EMST input or the MS command.
à
When the control mode is position control or velocity control.
l
Limiting function of acceleration/deceleration is invalid if the parameter AL is set to 0.
