Valve outputs | Command value limit
In this setting, the actuator activates the command value limit automatically
after an ETS programming operation. To deactivate the limit a "0" telegram
must be received via the "Command value limit" object. The limit can be
switched on or off at any time using the object.
The status of the command value limit is not automatically tracked in the com-
munication object after a device reset.
It is to be noted that, on account of priority control, the actuator executes the
behaviour configured by the parameters "Behaviour after bus voltage return"
and "Behaviour after an ETS programming operation" on the parameter page
"VOx - General" after bus voltage return and an ETS programming operation.
The command values preset via configuration after a device reset are not influ-
enced by a command value limit. A command value limit only influences the
input command values preset via the bus or emergency operation command
values during command value monitoring.

Activation
This parameter decides whether the limit of the command values can either be activ-
ated and deactivated by the "Command value limit" object or whether the command
value limit is permanently active.
Active after bus voltage return
This parameter decides whether the command value limit is activated or inactive
after voltage return.
Active after ETS programming operation
This parameter decides whether the command value limit is activated or inactive
after an ETS programming operation.
Minimum command value
The minimum command value that is valid when the command value limit is activ-
