Operation Timing
The timing with which the software limit function operates will depend on the
type of positioning performed.

1.
In the axis parameter area, set the software limits so that CCW software
limit
<
CW software limit.
2.
Establish the origin using origin search or present position preset (the No
Origin Flag turns OFF). The software limit function is disabled during origin
search.
3.
After the origin has been established, there are two times at which checks
are made: before positioning (pulse output is stopped) and during position-
ing (during pulse output). The timing of the checks varies with the opera-
tion as shown in the following table.

Setting range:
C0000001 to 3FFFFFFF Hex
(–1,073,741,823 to 1,073,741,823 pulses)
If the CCW software limit is greater than or
equal to the CW software limit, the software
limit function will be disabled.
Both the CCW and CW software limits
have the configuration shown below
Positioning operation
Check before positioning: Is the
position setting within the
software limits?
Check during positioning
Within range
Outside range
Direct operation
Absolute posi-
tioning or rela-
tive positioning
OK
Operation not
possible.
No check is performed unless the position
setting is changed during operation.
If the position setting is changed during
operation and the new position is outside the
software limit range, operation decelerates
to a stop to a position within the software
limit range.
Interrupt feeding
OK
OK
If the total number of pulses (the position)
output during speed control is outside the
software limit range, operation decelerates
to a stop to a position outside the software
limit range.
If the sum of the specified amount of move-
ment after the interrupt input and the num-
ber of pulses output until the interrupt input
is received is outside the software limit
range, operation decelerates to a stop to a
position outside the software limit range.
