Stored Stroke Limit Ii - Mitsubishi Electric C80 Series Instruction Manual

C80 Series Instruction Manual
7 Setting Machine Movable Area
CAUTION
Always set the stored stroke limit. Failure to set this could result in collision with the machine end.
The stored stroke limit sets a prohibited range with the parameters or program command. The minimum and maximum val-
ues of the prohibited range are set as the coordinate value (radius value) on the machine coordinate system for each axis.
The stroke check will not be executed when both maximum and minimum value are set to the same value.
This function is valid after the reference position return if the system does not apply the absolute position detection system.
Before the machine enters the prohibited range, an error "M01 Operation error 0007" (S/W stroke end) will occur, and the
machine movement will stop. The alarm can be reset by moving the erroneous axis in the opposite direction.
During automatic operation, if an alarm occurs with even one axis, all axes will decelerate to a stop.
During manual operation, only the axis that caused the alarm will decelerate to a stop.
The axis will always stop at a position before the prohibited range.
The distance between the prohibited range and stop position will depend on the feedrate, etc.
The stored stroke limits II and IIB are handled as follows.
Type Prohibited

II Outside Select II or IIB with
the parameters.
IIB Inside

7.1.1 Stored Stroke Limit II

The boundary is set with the axis parameters "#8204 OT-CHECK-N" and "#8205 OT-CHECK-P" or with program com-
mands. Either the inside or the outside of the set boundary is the prohibited range. Whether the inside or outside of the
range is prohibited is determined by "#8210 OT-INSIDE". When the inside is selected, this function is called stored stroke
limit IIB.
When using program commands, entry of the tool into the prohibited range is prohibited with G22, and entry into the pro-
hibited range is enabled with G23.
The stored stroke limit II can be invalidated for each axis with setting "#8202 OT-CHECK OFF" to "1".
