Operation setting when the speed limit value is exceeded

The operation when the speed of any axis exceeds the speed limit value during control can be specified in
AxisName.Pr.VelocityLimit_OverOperation.
The following two types can be selected for the operation when the speed exceeds the speed limit value.
• 0: Ignore (Ignore)
• 3: ImmediateStop (Immediate stop)
When the multiple axes exceed the limit value, the priority is "3: ImmediateStop" > "0: Ignore".
Control continuation
When "0: Ignore" is specified in AxisName.Pr.VelocityLimit_OverOperation, the error "Speed Limit Value Over during
Controlling" (error code: 1A36H) occurs at the time of detecting the set velocity exceeding the speed limit value, and the
command exceeding the speed limit value is output as it is.
Control stop
When "3: ImmediateStop" is specified in AxisName.Pr.VelocityLimit_OverOperation, the error "Speed Limit Value Over during
Controlling" (error code: 1A36H) occurs at the time of detecting the set velocity exceeding the speed limit value, and the
positioning control in execution stops.
