10-8-4 Software Limit Operation
The software limit function operates as described in the following table for the
present position when the software limits are set.
When a movement command is executed using direct operation for which the
target position will exceed the software limit range, the operation when the
software limit is reached will be as shown in the following diagram.

enabled
When the feedback present position for the
active axis reaches the forward/reverse soft-
ware limit, in the same way as when for-
ward/reverse rotation limit input signals are
input, the axis will stop and a For-
ward/Reverse Software Limit Error (error
code: 3002/3003) will occur.
Do not use this setting. Otherwise, the axis
operation will not be performed properly.
1
Forward software
limit disabled
The forward software limit is disabled.
When the feedback present position for the
active axis reaches the reverse software
limit, the axis will stop and a Reverse Soft-
ware Limit Error (error code: 3003) will
occur in the same way as when a reverse
rotation limit input signal is input.
2
Reverse software
limit disabled
The reverse software limit is disabled.
When the feedback present position for the
active axis reaches the forward software
limit, the axis will stop and a Forward Soft-
ware Limit Error (error code: 3002) will
occur in the same way as when a forward
rotation limit input signal is input.
3
Software limit dis-
abled in both direc-
tions
The software limits are disabled in both
directions.
The refresh range and positioning range for
the present position is
−
2,147,483,647 to
2,147,483,647 (command units), and the
possible operating range is within the for-
ward/reverse rotation limit input signal
range.
