!
ATTENTION: If you initiate a command to start
motor rotation (command a start or jog) and then
disconnect the programming device, the drive will not
fault if you have the SCANport communications fault
set to be ignored for that port.
Viewing the SCANport Fault Status
If a fault occurs while using SCANport, you can use parameters 442
and 443 to determine the port at which the fault was encountered.
Use parameter 442, SP Fault Sts, to view the fault status and
parameter 443, SP Warn Sts, to view the warning status. For either
parameter, you can use the following table to determine where the
problem was encountered:
This bit: Represents:
1 SCANport device 1
2 SCANport device 2
3 SCANport device 3
4 SCANport device 4
5 SCANport device 5
Using the SCANport Image
The SCANport image is a mechanism for transferring data between
SCANport devices and the drive. The SCANport image is used in
transferring real-time data in the same way as the PLC image is used.
The devices on SCANport allocate the SCANport image so multiple
devices can use different parts of the image. The image can can only
be used in a full rack. This allows a maximum of four devices to
access the drive at the same time.
You can view the values in the SCANport image table by using
parameters 314 through 321 for input and 343 through 350 for
output:
