In conjunction with parameter
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).
The table below lists the items that may selected for the data read/store function.
Select At Trip at this parameter to read/store the value of the item selected from
the table below in the event of a trip.
Select At Trigger at this parameter and set and activate a discrete input terminal
to Trace Back Trigger Signal to initiate the At Trigger read/store of the item
selected from the table below.
The duration of the read/store cycle for the selected data is set at parameter F741.
A communications device is required to use this parameter and a PC is used to
store the acquired data. The Q9 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).
Settings:
0 — None
1 — At Trip
2 — At Trigger
