BOARD
This menu relates to ES847 I/O expansion board. It can be viewed only if
R023
(I/O board setting) = XAIN (see the
EXPANSION BOARD CONFIGURATION MENU).
In addition to the analog inputs located on the control board, a current analog input and a voltage analog input can be
acquired if ES847 is fitted.
31.1.
Scaling Analog Inputs XAIN4, XAIN5
NOTE
Please refer to the Sinus Penta’s Motor Drives Accessories – User Manual for hardware details
about analog inputs.
Two analog inputs (XAIN4, XAIN5) are located on ES847 control board.
XAIN4 is a current input and XAIN5 is a voltage input. They are both bipolar analog inputs (–10V
÷
+10V or –20mA
÷
+20mA).
For both analog inputs, parameters
P390
to
P399
allow setting the type of signal to be acquired, offset compensation (if
any), scaling to obtain a speed reference or a torque reference, the signal filtering time constant.
Parameter
P393
sets the offset of the input analog signal (if
P393
=0 offset is zero), while parameter
P394
defines the
filtering time constant (factory setting:
P394
= 100ms).
The voltage signal can be bipolar (–
10V
÷
+10V
) or unipolar (
0V
÷
+10V
).
The current signal can be bipolar (
–20mA
÷
+20mA
), unipolar (
0mA
÷
+20mA
)
or can have a minimum offset (
4mA
÷
20mA
).
The user will set each analog input mode in parameters
P390
,
P395
.

NOTE
Configurations different from the ones stated in the table above are not allowed.
Scaling is obtained by setting the parameters relating to the
linear function for the conversion
from the value read by
the analog input to the corresponding speed/torque reference value.
The
conversion function
is a
straight line
passing through
2 points
in
Cartesian coordinates
having the values read
by the analog input in the X-axis, and the speed/torque reference values in the Y-axis. The speed/torque reference
values are multiplied by the reference percent parameters.
Each point
is detected through its
two coordinates
.
The ordinates of the two points are the following:
the value of
Speed_Min
(or
Trq_Min
for the torque reference) multiplied by the percentage set with
P391a/P396a
for
the
first point
; the value of
Speed_Max
(or
Trq_Max
for the torque reference) multiplied by the percentage set with
P392a/P397a
for the
second point
.
Speed_Min
depends on the selected motor: see parameter
C028
(motor 1),
C071
(motor 2), or
C114
(motor 3).
Trq_Min
depends on the selected motor: see parameter
C047
(motor 1),
C090
(motor 2) or
C133
(motor 3).
Speed_Max
depends on the selected motor: see parameter
C029
(motor 1),
C072
(motor 2) or
C115
(motor 3).
Trq_Max
depends on the selected motor: see parameter
C048
(motor 1),
C091
(motor 2), or
C134
(motor 3).
The X-axis values of the two points depend on the analog input:
XAIN4
Input:
Parameter
P391
is the X-axis of the
first point;
parameter
P392
is the X-axis of the
second point.
