Explanation
Sets the travel distance for STEP operation.
Name
Positive direction software limit
Setting range
80000000 to 7FFFFFFF Hex
00
(−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 0.01mm unit (P5AA01, P5AA2)
within − 100 to 100mm, the following values are to be set:
P3AA02 = 100mm/0.01mm = 10000 [command unit]
P3AA03 = − 100mm/0.01mm = − 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).
Name
Negative direction software limit
Setting range
80000000 to 7FFFFFFF Hex
00
(−2147483648 to 2147483647)
Explanation
Sets the software limit value in the negative direction.
An error will occur when the command value created in every unit scan is
smaller than this software limit.
(See the setting example of P3AA02: + direction software limit on page 77.)
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).
