Parameters 167
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.
-
0.000…20.000 mA
or 0.000…10.000 V
Value of analog input AI1.
1000 = 1 unit
Displays the value of analog input AI1 after scaling. See
parameters
and
.
This parameter is read-only.
-
-32768.000…
32767.000
Scaled value of analog input AI1.
1 = 1
Forced value that can be used instead of the true reading of
the input. See parameter
-
0.000…20.000 mA
or 0.000…10.000 V
Forced value of analog input AI1.
1000 = 1 unit
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
(page
). Control board reboot (either by cycling the
power or through parameter
) is
required to validate any changes in the hardware settings.
V
Volts.
2
mA
Milliamperes.
10
Defines the filter time constant for analog input AI1.
Note:
The signal is also filtered due to the signal interface
hardware (approximately 0.25 ms time constant). This cannot
be changed by any parameter.
0.100 s
0.000…30.000 s
Filter time constant.
1000 = 1 s
No.
