Analog Outputs (AO)
All analog outputs (AO) points have the following features:
● Support Change of State (COS) reporting based on override status.
● Always considered reliable.
● Overriding of the AO points is the method used to change a value. Overriding an AO point with a value
beyond the limit allowed by the drive’s internal variable will result in an Invalid Data error and the
override status and value will remain unchanged. If the overridden value is beyond the drive’s parameter
limit but within the range that will fit in the variable, an acknowledge response is given and the value will
be internally clamped to its limit.

Binary Outputs (BO)
All binary outputs (BO) points have the following features:
● Support Change of State (COS) reporting based on override status.
● Always considered reliable.
● Overriding BO points control the drive. These points are input commands to the drive. When released, the
drive’s internal value remains at its last overridden value.
