Description
Drive generates an A7EE Control panel loss
only occurs if control is expected from the control panel, or if
supervision is forced using parameter
supervision force.
WARNING! Make sure that it is safe to continue
operation in case of a communication break.
Applies the settings of parameters 49.01...49.05.
Note: Refreshing may cause a communication break, so
reconnecting the drive may be required.
Refresh done or not requested.
Refresh parameters 49.01...49.05. The value reverts
automatically to Done.
Activates control panel communication monitoring separately
for each control location (see section
external control on page 20).
The parameter is primarily intended for monitoring the
communication with the panel when it is connected to the
application program and not selected as a control source by
drive parameters.
Value
1 = Communication monitoring active when Ext 1 is being used.
1 = Communication monitoring active when Ext 2 is being used.
1 = Communication monitoring active when local control is being
used.
Panel communication monitoring selection.
Selects how the drive reacts to a control panel (or PC tool)
communication break. This action is taken when
• the panel is parametrized as an alternative control or
reference source but is not currently the active source, and
• communication supervision for the active control location is
not forced by parameter
force.
No action taken.
