FLOWCHART A
Selecting the Reference
Sources
In the
Motor 1 Control
menu,
select the type of
speed/torque reference (
C011
). The
Control Method
menu
includes
the parameters selecting the reference
source.
You can set up to four sources, which are summed up
to each other. For speed control, and if references are
to be sent also from
digital inputs
, see the
Multispeed
menu
.

The reference scaling is obtained through
the parameters included in the
Input
Reference
menu. Each source is assigned
to a parameter setting its min. value and
max. value for the min./max. speed/torque
reference of the connected motor (e.g.
Motor 1 speed reference:
C028
for min.
speed,
C029
for max. speed.
Torque reference:
C047
for min. torque,
C048
for max.
torque)
No reference scaling is required. Speed
references are expressed in rpm, torque
references are expressed as a percentage of the
motor rated torque. Saturation of the reference
values depends on Min. Speed and Max. Speed
parameters (speed control), and on Min. Torque
and Max. Torque parameters (torque control).
(E.g. Motor 1 speed:
C028
for min. speed,
C029
for max. speed; Motor 1 torque:
C047
for min.
torque,
C048
for max. torque)
