Configuration of the AX1 module
Analogue input ports used as indicator input are pre-
configured in the “VI-setup” profile (VS) defined for a virtual
indicator (VI); this is also the case if DIM/HV3 is used as indicator input.
The configuration of the analogue dimmer input is pre-configured in the selected Product Profile (PP).
Menu access:
The default settings of the extension module may be changed/adjusted via the XDi menu system.
Adjustment of dimmer settings is in the
“User menu”, and indicator input settings are located in the more protected
“Installation menu”.
Via the installation menu, it is possible to adjust the analogue setup parameters, for example calibrate the zero
point, adjust max/min scaling values, or change direction of the scaling (CW/CCW) and much more.
Please see
the “Installation menu” section for detailed information.
The available analogue inputs on the AX1 can be configured as follows:
Type
Input
Type
Note
Sin cos input
Port 1 = SIN and
Port 2 = COS
High voltage, max. +/-30 V or
High current, max. +/-20 mA
Input pair
Double triangle
input
Port 1 = input 1
Port 2 = input 2
High voltage, max. +/-30 V or
High current, max. +/-20 mA
Input pair
Single input
Port 1 or
Port 2
High voltage, max. +/-30 V or
High current, max. +/-20 mA or
Low current, max. +/- 2 mA or
Low voltage, max. +/- 2 V DC
Low current and Low voltage
use the same input connectors.
Single input
Port 3 (Dim)
High voltage, max. +/-30 V DC
Dimmer input.
Is fully calibrated and can also
be configured as an indicator
high voltage input (3).
High accuracy
potentiometer
input
Port 1,
Port 2 or
Port 3 (Dim)
High voltage, default 0 to 7.3 V (=
Vref)
Vref is continuously measured and
may be overwritten by an external
voltage b7.5 and +30 V DC
The input to output scaling is
made relative to Vref and
thereby corrected for drift or
fluctuations in the reference
voltage also if it is overwritten.
5.6.9.1 Sin/cos dual input with +/- 10V supply to the potentiometer
Input 1 and 2 can be predefined in the VS as a SIN/COS input pair. This type of input is often used for 360° angle
measurements, and the input signals are provided by a special double potentiometer, supplied by the same voltage
source.
If you by accident select a PP and a VS profile that are both set up to configure the DIM/HV3
input port, then the XDi will assign port 3 as dimmer input as defined by the product profile (PP)
and the virtual indicator (VI) will miss the input configuration and indicate that analogue input
data is lost!
