Explanation
When the equipment connected to IFD9502 is an AC motor drive, the length of data downloaded
from IFD9502 to the AC motor drive is preset as 2 words at addresses H'2000 and H'2001.
IFD9502 is able to download maximum 8 words to AC motor drive. The length of data uploaded
to IFD9502 from AC motor drive is preset as 2 words at addresses H'2101 and H'2102 and
IFD9502 is able to be uploaded maximum 8 words.
The length of data transmitted from IFD9502 to the AC motor drive is preset as 2 words. If you
need to extend the length, you have to first set up Class 0x95>>Instance1>>Attribute2 as the
destination value and next set up Attribute11 ~ Attribute 18. The length of data transmitted from
the AC motor drive to IFD9502 is preset as 2 words. If you need to extend the length, you have to
first set up Class 0x95>>Instance1>>Attribute3 as the destination value and next set up
Attribute25 ~ Attribute32.
Length of I/O data to be exchanged and address for I/O mapping can be modified through
changing Class 0x95 as listed below. The modification will be valid after IFD9502 is re-powered.
Maximum 16 words are allowed for I/O data exchange.
If you are to return the I/O mapping to default setting, change Attribute1 of Instance1 of Class
0x95 into H'0001 and re-power IFD9502. Please note that doing so can only recover the current
I/O data mapping in the AC motor drive.
