Notes:
ƒ

The transmission type for mapping this object must be 255; otherwise, an Abort
message (code 0604 0043h) will be transmitted.

ƒ

When this object is used to feed PVT reference points to the drive while a PVT
motion is executing, the drive automatically enters Online Feed mode, in which
the drive is aware of the position written and takes the following precautions:

ƒ

If the feed is too slow, the drive needs to fetch points not yet programmed,
and the motion will abort with a “Queue underflow” emergency.

ƒ

If the feed is too fast, so that points not yet used are overstruck, the drive will
reject the feed attempt with a “Queue overflow” emergency.

ƒ

The Online Feed mode will continue until at least one setting of PVT parameters
has been completed without using the RPDO.
