7.3.21
Trace Function [41]
The trace function is used to register variables of interest of the CTW900 (such as current, voltage, speed) when
a certain event occurs in the system (alarm/ fault, high current, for instance). This event, for triggering the data
storage process, is called trigger in this manual.
Once collected, the variables stored can be viewed as graphics by using the SuperDrive G2 software.
P0550 – Trigger Source for Trace
Adjustable Range:
0 = Inactive
Factory Setting:
0
1 = Total Reference
2 = Present Speed
3 = Armature Current
4 = Armature Voltage
5 = Field Current
6 = Motor Torque
7 = AI1
8 = AI2
9 = AI3
10 = AI4
Properties:
Groups of
01 PARAMETER GROUPS
Access via HMI:
41 Trace Function
........
Description:
It selects the variable that will be used as trigger source for the Trace function.
These variables can be also used as signal to be collected by means of parameters P0561 to P0564.
NOTE!
This parameter has no effect when P0552 = “Alarm”, “Fault” or “DIx”.
P0551 – Trigger Value for Trace
Adjustable Range:
-100.0 to 150.0 %
Factory Setting:
0.0 %
Properties:
Groups of
01 PARAMETER GROUPS
Access via HMI:
41 Trace Function
........
Description:
It defines the comparison value for the variable selected on P0550.
The full scale of the variables selectable as trigger is shown in the following table:

– Full scale of the variables selectable as trigger for the Trace function
Variable
Full Scale
Total Reference
100 % = P0134
Present Speed
100 % = P0134
Armature Current
100 % = P0401
Armature Voltage
100 % = P0400
Field Current
100 % = P0404

100 % = 10 V / 20 mA
AI2
100 % = 10 V / 20 mA
AI3
100 % = 10 V / 20 mA
AI4
100 % = 10 V / 20 mA
