NOTE
I025
is the speed reference if at least one among parameters
C143
..
146
is set to
5:Serial Link and the type of reference of the active motor (parameters
C011
/
C054
/
C097
) is set to 0:Speed; I025 is the speed limit if
C147
=5:Serial Link and the type of
reference of the active motor is set to 2:Torque with Speed Limit. The range of this
reference depends on the active Minimum Speed value and Maximum Speed value as
set in parameters
C028
and
C029
(for motor 1, and relevant parameters for motor 2 and
motor 3).
If
C029
≤
C028
, then
Min. speed
=
C029
,
Max. speed
=
C028
.
If
C029
≥
C028
, then
Min. speed
=
C028
,
Max. speed
=
C029
.
NOTE
I026
is the decimal portion of the speed reference in RPM and has effect in
FOC
motor
control mode only.
NOTE
I029
is used as a torque reference if at least one among parameters
C143
..
146
is set to
5:Serial Link and the type of reference of the active motor (parameters
C011
/
C054
/
C097
) is set to 1:Torque or 2:Torque with Speed Limit.
I029
is used as a torque limit if
C147
=5:Serial Link.
I029
is expressed as a percentage of the max. absolute torque set with the parameters
C047
and
C048
(motor 1, and relevant parameters for motor 2 and motor 3). The max.
absolute torque is the max. value between absolute values of parameters
C047
and
C048
.
Max. absolute torque
= Max( |
C047
| , |
C048
|)
The unit of measure is tenths of %:
Torque reference
% = (
I029
*0.1) %
Reference range:
If
C047
≤
C048
, then
Min. torque
=
C047
,
Max. torque =
C048
.
If
C047
≥
C048
, then
Min. torque
=
C048
,
Max. torque
=
C029
.
Example: 1200 = 120.0%
FIELDBUS

KEYPAD
NOTE
The keypad is a special reference source. The keypad reference may be changed with
the
▲
and
▼
keys only if this reference is on a Keypad page displaying a reference in
line 4.
If the keypad is enabled, a
variation
to the active reference may be added through an
algebraic sum (calculated by processing the other reference sources that are activated
at that moment).
The reference variation method can be selected with parameters
P067
,
P068
,
P069
, and
C163
.
This function is the same as the
UP
and
DOWN
functions from the terminal board (see
C161
and
C162 and P068÷P069
in the INPUTS FOR
NOTE
The
LOCAL mode,
that can be enabled with the
LOC/REM
key on the keypad or with
the
LOCAL
command function from terminal board (see
C180
), forces the keypad to
become the only command and reference source, thus ignoring the values set in
parameters
C143
,
C144
,
C145, C146
.
