Trace Selection
Program Utilities Trace
In conjunction with parameter F741
and store 4 ASD output waveform data points. The data may be read and stored
as a function of a trip (At Trip) or it may be initiated by the activation of a
discrete terminal activation (At Trigger).
Set a discrete input terminal to Trace Back Trigger Signal and activate the
terminal to initiate the At Trigger read/store function.
Table 10 on pg. 241 lists the items that may be selected for the data read/store
function along with the associated communication number for each selection.
The duration of the read/store cycle for the selected items is set at parameter
F741.
To acquire and store the data a communications device and a PC are required.
The G9 ASD supports the following communications protocols: RS485
(MODBUS-RTU) Toshiba Protocol, USB Toshiba Protocol, CC-Link,
ProfiBus, and DeviceNet (Refer to the manual of each protocol type for more
information).
Trace data may be viewed graphically via Program  Utilities  View Trace
Data.
Settings:
0 — None (Disabled)
1 — At Trip
2 — At Trigger
