Open Node dialog
In the Open Node dialog you specify data for a single component node. There are four different kinds of nodes; each treated slightly different in this dialog box.
Parameters common to all nodes are:
Name A six or five (n-phase components) characters long node name. The parameter caption is read from the support file. If you try to type in a name on the reserved ATPDraw format (XX1234 for single phase or X1234 for three-phase nodes) you will be warned. Ignoring this warning can result in unintentional naming conflicts.
On screen If checked, the node name is written on screen, regardless of the current setting of the Node names option in the View Options dialog box.
UserNamed This checkbox shows whether this node name is specified by the user or ATPDraw. If the user wants to change a user specified node name he must do this where the UserNamed box is checked. If not, duplicate node name warnings will appear during the compilation. Node with UserNamed set are also drawn with a red node dot.
The phase sequence appears after compile circuit is performed (ATP|Run ATP or ATP|Sub-process/Make node names). Transposition is only possible for 3-phase nodes. A four-phase node will have the phase sequence A..D. The user can connect a single phase connection to this node and specify which phase to connect to in the Connection dialog.
The following list explains the type specific node parameters.
Standard and user specified component node:
Ground If checked, the node is grounded. Click on the ground symbol to rotate it.

The Open Node dialog box for standard and user specified components.
Model node:
Type 0=Output.
1=Input current (i)
2=Input voltage (v)
3=Input switch status (switch)
4=Input machine variable (mach)
5=TACS variable (tacs)
6=Imaginary part of steady-state node voltage (imssv)
7=Imaginary part of steady-state switch current (imssi)
8=Output from other model. Note that the model that produces this output must be USEd before the current model. This is done by specifying a lower group number for the model and then select the Sorting by group number option under ATP|Settings/Format.
9=Input of global ATP variable MNT=simulation number...
TACS node:
Type 0=Output.
1=Input signal positive sum up.
2=Input signal negative sum up.
3=Input signal disconnected.
(only necessary if node name is user specified)
TACS controlled machine node:
Type 0=No control.
1=D-axis armature current. Out.
2=Q-axis armature current. Out.
3=Zero-sequence armature current. Out.
4=Field winding current. Out.
5=D-axis damper current. Out.
6=Current in eddy-current winding. Out.

10=Zero-sequence voltage. Out.
11=Voltage applied to field winding. Out.
12=Total mmf in the machines air-gap. Out.
13=Angle between q- and d-axis component of mmf. Out.
14=Electromagnetic torque of the machine. Out.
15=Not in use.
16=d-axis flux linkage. Out.
17=q-axis flux linkage. Out.
