Explanation:
When the equipment connected to IFD9502 is a servo drive, the length of data downloaded
from IFD9502 to the servo drive is preset as 1 word at addresses H’0407 (corresponding
address of DI1 ~ DI8). IFD9502 is able to download maximum 16 words. The length of data
uploaded to IFD9502 from the servo drive is preset as 1 word at addresses H’0409
(corresponding address of DO1 ~ DO5). IFD9502 is able to be uploaded maximum 16
words.
The length of I/O data to be exchanged and address for mapping can be modified through
changing Class9B s listed below. The modification will be valid after IFD9502 is re-powered.
Maximum 32 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 0x9B into H’0001 and re-power IFD9502. Please note that doing so can only recover
the current I/O data mapping in servo drive.
