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.
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.
Selects the unit for readings and settings related to analog
input AI1.
Note: This setting must match the corresponding hardware
setting on the drive control unit (see the hardware manual of
the drive). Control board reboot (either by cycling the power
or through parameter 96.08 Control board
validate any changes in the hardware settings.
