Selecting the Reference
Sources
Motor 1 Control menu, select the type of
C011). The Control Method
includes the parameters selecting the reference
You can set up to four sources, which are summed up
to each other. For speed control, and if references are
to be s
ent also from digital inputs, see the Multispeed
.
Forcing the Reference Sources
REF Ref Analog Input
AIN1 AIN1 Analog Input
AIN2 AIN2 Analog Input
Pulse Input Frequency Input (MDI8)
Encoder Encoder Input
Serial Link Reference from serial link
Fieldbus Reference from fieldbus
Keypad Ref. from display/keypad
Preset Speed Reference from digital
input
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)
