11.2 Speed Limit Function
11.2 Speed Limit Function
The "speed limit function" limits command speed to the value set in " Speed limit value" when command speed
during major positioning control or JOG operation exceeds " Speed limit value".
(1) Control detail
This function is active on major positioning control and JOG operation.
When the value set in " Speed limit value" is exceeded in each control, command speed is limited to
" Speed limit value".
The operation of the speed limit function is as follows.
In the figure above, the speed set in " Speed limit value" is output since " Positioning speed V1" is
faster than " Speed limit value". In this case, the movement amount that was not output because of the
speed limit (1 in the figure) is output later (2 in the figure), delaying the positioning completion.
(2) Precautions for control
Set positioning speed and JOG speed to a value equal to or less than " Speed limit value". If " Speed
limit value" is exceeded, command speed is limited to " Speed limit value".
Also, set OPR speed to a value equal to or less than " Speed limit value". If " Speed limit value" is
exceeded, the error "OPR speed Outside the setting range" (error code: 20) occurs at the start of OPR.
