3.32.1 Enable Channel Check Box
By default, the analog output channels are not enabled meaning that a value is not being sent to the analog circuit. When the
channel is disabled (check box is clear), the configuration parameters for that analog output are unavailable and therefore
have no effect. To enable the output, simply select the Enable Channel check box, and the configuration parameters will
become available to edit.
If the user wishes to control the Analog Output through other means, it is necessary to clear the Enable Channel check box.
3.32.2 Source
This list box allows the user to create a direct connection from a Source parameter to the Analog Output. The current value of
the parameter selected as the Source will directly determine the value of the Analog Output signal. The Source list box
contains a list of predefined parameters to select from.
Custom Variable
The Custom Variable parameter is only available once the user has selected Custom Variable from the Source list box above.
This text box is used to define what parameter will control the Analog Output. The selected parameter will directly determine
the value of the analog output based on the Max and Min scaling values entered on this view. The parameter is entered here
in program format or see Popup Variables Button, below.
Popup Variables Button
Click this button to open the Select Variables from Tree window. Select the variable and drag the variable over to the Custom
Variable text box to assign the variable to the Analog output channel.
3.32.3 Maximum Value
The analog output is a linear interpolation of the selected drive variable between the minimum and maximum specified end
points. Each end point is specified as the user value and the corresponding output value at that point. The number of decimal
places for both values is taken from the selected drive variable. MaxUserValue is the maximum user unit value which
corresponds to the maximum analog output value.
3.32.4 Maximum Output
The analog output is a linear interpolation of the selected drive variable between the minimum and maximum specified end
points. Each end point is specified as the user value and the corresponding output value at that point. The number of decimal
places for both values is taken from the selected drive variable. MaxOutputValue is the maximum analog output value which
corresponds to the maximum user value.
3.32.5 Minimum Value
The analog output is a linear interpolation of the selected variable between the minimum and maximum specified end points.
Each end point is specified as the user value and the corresponding output value at that point. The number of decimal places
for both values is taken from the selected variable. MinUserValue is the minimum user unit value which corresponds to the
minimum analog output value.
3.32.6 Minimum Output
The analog output is a linear interpolation of the selected variable between the minimum and maximum specified end points.
Each end point is specified as the user value and the corresponding output value at that point. The number of decimal places
for both values is taken from the selected variable. MinOutputValue is the minimum analog output value which corresponds to
the minimum user value.
3.32.7 Feedback
Analog Output Feedback is the Analog output voltage to be sent out after scaling the selected source parameter.
3.33 Motion Group
All motion parameters related to Jogs, Homes, Indexes, Gearing and Camming are located in the Motion hierarchy group.
Motion views will use units that correspond to Realtime or Synchronized motion. This choice is made on each motion view.
The units are customized in the Setup Group: Realtime units are defined on the User Units View, and Synchronized units are
defined on both the User Units View and the Master Units View.
Each of the motion views, when online, have an Online tab that displays feedback information and provides buttons to initiate
motion.
3.34 Jog View
Jogging produces rotation of the motor at controlled velocities in a positive or negative direction. The jog is initiated with the
Jog.#.Initiate destination or from a program.
