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 Sp
eed 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 m
ax. 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
For a description of the Fieldbus source, see the FIELDBUS CONFIGURATION MENU.
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
the DIGITAL INPUTS MENU: C161 and C162 and P068÷P069 in the
INPUTS FOR
REFERENCES MENU).
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.
