Explanation
Sets the travel distance for STEP operation.

Positive direction software limit
Setting range

(−2147483648 to 2147483647)
Explanation
Sets the software limit value in the positive direction.
An error will occur when the command value created in every unit scan
exceeds this software limit.
The value has to satisfy the following conditions:
P3AA02 [command unit] = + direction upper limit/minimum setting unit
P3AA03 [command unit] = − direction upper limit/minimum setting unit
P3AA03 < P3AA02
Ex) When positioning X-axis (ball screw) in 0.01 mm unit (P5AA01, P5AA2)
within − 100 to 100 mm, the following values are to be set:
P3AA02 = 100mm/0.01 mm = 10000 [command unit]
P3AA03 = − 100mm/0.01 mm = − 10000 [command unit]
The setting of this parameter is ignored in the following cases:
• When Software limit enabled/disabled (P3AA04) is set to either 0 or 2.
• When an origin has not been defined.
• When Axis feed mode (P5AA07) is set to 0010h (unlimited length).
