Description
Drive generates a warning
speed to the speed defined by parameter
safe (or 28.41 Frequency ref safe
is being used).
WARNING! Make sure that it is safe to continue
operation in case of a communication break.
Specifies the analog input limits to be supervised. See
parameter 12.03 AI supervision
Description
1 = Minimum limit supervision of AI1 active.
1 = Maximum limit supervision of AI1 active.
1 = Minimum limit supervision of AI2 active.
1 = Maximum limit supervision of AI2 active.
Activation of analog input supervision.
Activates analog input supervision separately for each control
location (see section Local control vs. external control
page 20).
The parameter is primarily intended for analog input
supervision when the input is connected to the application
program and not selected as a control source by drive
parameters.
Description
1 = AI1 supervision active when EXT1 is being used.
1 = AI1 supervision active when EXT2 is being used.
1 = AI1 supervision active when local control is being used.
1 = AI2 supervision active when EXT1 is being used.
1 = AI2 supervision active when EXT2 is being used.
1 = AI2 supervision active when local control is being used.
Analog input supervision selection.
Displays the value of analog input AI1 in mA or V (depending
on whether the input is set to current or voltage by a hardware
setting).
This parameter is read-only.
Value of analog input AI1.
Displays the value of analog input AI1 after scaling. See
parameters 12.19 AI1 scaled at AI1 min
at AI1 max.
This parameter is read-only.
Scaled value of analog input AI1.
