19 TRACE FUNCTION [52]

19.1 TRACE FUNCTION

The trace function is used to record variables of interest from the CFW-11 (as current, voltage, speed) when a
particular event occurs in the system (e.g.: alarm/fault, high current, etc.). This system event, for starting the data
recording process, is called "trigger". The stored variables can be visualized as graphs through the SuperDrive
G2 executed by a PC connected via USB or Serial to the CFW-11.
The parameters related to this function are presented next.
P0550 – Trigger Signal Source
Adjustable 0 = Not selected
Range: 1 = Speed Reference
2 = Motor Speed
3 = Motor Current
4 = DC Link Voltage
5 = Motor Frequency
6 = Motor Voltage
7 = Motor Torque
8 = Process Variable
9 = PID Setpoint
10 = AI1
11 = AI2
12 = AI3
13 = AI4

Description:
It selects the variable that will be used as the trigger source for the Trace Function.
This parameter has no effect when P0552 = "Alarm", "Fault" or "DIx".
Those same variables can also be used as signals to be acquired, through the parameters from P0561 up to
P0564.
