Overrun At Stop Cause Occurrence - Mitsubishi Electric MELSEC iQ-R Series User Manual

Overrun at stop cause occurrence

This function selects operation for the case that the positioning address of an instruction which was executed before a stop
cause occurs is reached during deceleration stop and immediate stop process.
This function is enabled only when the target position exists at stop cause occurrence.
The following parameters for a single axis or an axes group are need to be set in this function.
• Single axis: AxisName.Pr.OverrunOperation
• Axes group: AxesGroupName.Pr.OverrunOperation
AxisName.Pr.OverrunOperation and AxesGroupName.Pr.OverrunOperation have the following two functions.
Immediate stop
1: ImmediateStop
The operation is immediately stopped when reaching the original positioning address during deceleration by a stop cause. In
this case, the operation does not exceed the positioning address set in the on-going FB.
New stop cause occurrence
Original deceleration curve
(automatic deceleration, etc.)
Keep current acceleration/deceleration (Only for a single axis)
2: KeepCurrentAcc
Deceleration continues even though the operation reached the original deceleration stop position during deceleration by a
stop cause. In this case, there is no guarantee that it stops before the positioning address set in the on-going FB.
New stop cause occurrence
