E70 Series Instruction Manual
7.1 Stored Stroke Limit
II - 61
The stored stroke limit sets a prohibited range with the parameters or program command. The maximum and minimum
values of the prohibited range are set as coordinate values (radius values) on the basic machine coordinate system for
each axis. If the parameters (#8204 OT-CHECK-N and #8205 OT-CHECK-P), for setting the prohibited range, are set to
the same value, the stroke will not be checked. This function is valid only for the axis for which the reference position is
established.
If the machine enters the prohibited range, an operation error 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.
The stored stroke limits I, II are handled as follows.
7.1.1 Stored Stroke Limit I
This is a stroke limit function used by the machine tool builder. The boundary is set with the parameters ("#2013 OT -
(Soft limit I -)" and "#2014 OT + (Soft limit I +)"). The outside of the set boundary is the prohibited range. The outside of
the set boundary is the prohibited range.
When used with the stored stroke limit II function, the confined range designated by the two functions becomes the
moveable range.
: Moveable range
: Prohibited range
(A): Set value for (-) side
(B): Set value for (+) side
Point 1: "#2014 OT+ (Soft limit I +)" and
Point 2: "#2013 OT- (Soft limit I -)" are set with the coordinate values in the basic machine
coordinate system.
(Note)
This function will be invalid if the same value excluding "0" is set for both "#2013 OT -" and "#2014 OT +".
