Parameters 189
Speed ref safe Drive generates a warning (A8A0 AI supervision) and sets the
speed to the speed defined by parameter 22.41 Speed ref
safe (or 28.41 Frequency ref safe when frequency reference
is being used).
WARNING! Make sure that it is safe to continue
operation in case of a communication break.

12.04 AI supervision
selection
Specifies the analog input limits to be supervised. See
parameter 12.03 AI supervision function.
0b0000
0b000...0b1111 Activation of analog input supervision. 1 = 1
12.11 AI1 actual value 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.
0
0.000…11.000 V Value of analog input AI1. 1000 = 1 unit
12.12 AI1 scaled value Displays the value of analog input AI1 after scaling. See
parameters 12.19 AI1 scaled at AI1 min and 12.20 AI1 scaled
at AI1 max.
This parameter is read-only.
0
-32768.000…
32767.000
Scaled value of analog input AI1. 1 = 1
12.13 AI1 forced value Forced value that can be used instead of the true reading of
the input. See parameter 12.02 AI force selection.
0
0.000…11.000 V Forced value of analog input AI1. 1000 = 1 unit
12.15 AI1 unit selection Selects the unit for readings and settings related to analog
input AI1.
Note:
In firmware ASCL2 and ASCL4), this setting must
match the corresponding hardware setting on the drive
control unit. See chapter Electrical installation, section
Switches in the Hardware manual of the drive and the default
control connections for the macro in use in chapter Control
macros (page 101). Control board reboot (either by cycling
the power or through parameter 96.08 Control board boot) is
required to validate any changes in the hardware settings.
