User name for this axis can have a length up to 12 characters. This can be used to help differentiate setup files.
Packed Bits Control Word Value
PackedBits.ControlWord.#.Value
When accessing the Packed Bits Control Words for network mapping or use in a program, the Value parameter is what holds the data. When
used in a program, the "PackedBits." and the ".Value" portions of the parameter name are optional. Therefore, to write to the Control Word
Value in a program, the following lines of code are all interchangeable:
PackedBits.ControlWord.0.Value = 5
PackedBits.ControlWord.0 = 5
ControlWord.0.Value = 5
ControlWord.0 = 5
Packed Bits Status Word Value
PackedBits.StatusWord.#.Value
When accessing the Packed Bits Status Words for network mapping or use in a program, the Value parameter is what holds the data. When
used in a program, the "PackedBits." and the ".Value" portions of the parameter name are optional. Therefore, to read the Status Word Value in
a program, the following lines of code are all interchangeable:
Var.MyVar = PackedBits.StatusWord.0.Value
Var.MyVar = PackedBits.StatusWord.0
Var.MyVar = StatusWord.0.Value
Var.MyVar = StatusWord.0
PLS Direction
PLS.#.Direction
This parameter specifies the direction of motion that a particular PLS output will function. If set to Both, the PLS will activate regardless of
whether the axis is moving in the positive or negative direction. If set to Plus, the PLS will activate only when the axis is moving in the positive
direction. If set to Minus, the PLS will activate only when the axis is moving in the negative direction. When set to Plus or Minus the PLS Status
will activate when the position of the PLS source is > or = to the on position, + or < the off position. See PLS View on page 56 for more
information on how the PLS feature works.
A flying cutoff or flying shear application may use this feature to activate the PLS to fire the knife only when the axis is moving in the positive
direction.
PLS Off Point
PLS.#.OffPosn
PLS.#.Status will be active when the selected source position is between the PLS.#.OnPosn and the PLS.#.OffPosn. The terms On and Off
assume you are traveling in a positive direction.
With the PLS.#.Direction set to "Both". The PLS.#.Status will activate when traveling in the positive direction and the position feedback reaches
the OnPosn. As the motor continues in the same direction, the PLS.#.Status will deactivate when the source reaches or exceeds the OffPosn.
If motor travel changes to the negative direction after passing the OffPosn, the PLS.#.Status will activate when position feedback reaches the
OffPosn, and will deactivate when it continues past the OnPosn. The important thing to remember is that the PLS.#.Status will be active
between the PLS On and Off points.
If using negative values for the OnPosn and OffPosn, the most negative value should go in the OnPosn parameter, and the least negative
value should go in the OffPosn.
If the PLS has a rollover point, and the OnPosn is greater than the OffPosn, the PLS will be active whenever the axis is not between the On
and Off positions, and inactive whenever the axis is between the two positions. However, the PLS.#.Status will not turn on until it reaches the
OnPosn the first time.
PLS On Point
PLS.#.OnPosn
PLS.#.Status will be active when the selected source position is between the PLS.#.OnPosn and the PLS.#.OffPosn. The terms On and Off
assume the motor is traveling in a positive direction.
Assume the PLS.#.Direction is set to "Both". When traveling in the positive direction and the source reaches the OnPosn, the PLS.#.Status will
activate. As the motor continues in the same direction, the PLS.#.Status will deactivate when feedback position reaches or exceeds the
OffPosn. If motor travel changes to the negative direction, the PLS.#.Status will activate when position feedback reaches the OffPosn, and will
deactivate when it continues past the OnPosn. The important thing to remember is that the PLS.#.Status will be active if between the PLS On
and Off points.
If using negative values for your OnPosn and OffPosn, the most negative value should go in the OnPosn parameter, and the least negative
