Update notice
CHANGED (page 90): Cyclic high priority communication
The minimum update cycle time for the following drives is:
ACSM1, ACS850 and ACS880: 500 us (2000 Hz)
ACS355: approximately 4 ms (250 Hz)
ACS580: 2 ms (500 Hz)
Use the high priority service for axis commands and feedback data, ie, torque, velocity and
position commands and feedback values. There is room for the drive control word and reference
values (command values) and the drive status word and two actual values (feedback values).
The values of the following objects are transferred – or the data where the values of the
following objects are derived is transferred – between the drive and the adapter module via the
cyclic high priority service.
Note: Since there is room only for two feedback values, the CiA 402 feedback data objects will
not be operational unless the corresponding feedback data has been selected to be transmitted
from the drive. See sections
examples – ACS850
