Analog Output X
Menu group to configure the analog output X. Changes to the calibration values made in this group, act only on the indicated analog
output and not on the others.
An.Out. X source
Parameter that allows you to select the source of the outgoing analog reference. Using the keys you can select the source from among
these:
•
NOT USED
: the analog output is not used and the “Value” is always at 0 %.
•
MOTOR TORQUE
: the analog output (standard on AO1) indicates the motor torque in percentage value. When the para-
meter “Value” reaches 100 % it means that the motor is subjected to the rated load and that it may lose speed if it is charged
further.
•
MOTOR SPEED
: the analog output (standard on AO2) indicates the motor speed with this scale:
Speed
=
Value
100
⋅
Maximum Speed
Value = Value shown in the parameter “Value” of the analog
output under consideration (see Drawing 16).
Maximum Speed = Maximum speed of the motor as inserted in the
parameter ”Maximum speed“ on page 37.
Speed = Speed of the motor in RPM.
•
DC BUS VOLTAGE
: the analog output (standard on AO4) indicates a value proportional to the DC BUS voltage. If the
parameter “Value” is 100 % means that the voltage on the DC BUS is 881Vcc.
•
AI1 VALUE
: the analog output indicates the value measured by the analog input n.1. The parameter “Value” of the analog
output has the same value as the parameter “Value” of the analog input 1, so it is not possible to define an exact scale as it de-
pends on the calibration parameters of the analog input 1. It is as if the calibration block of the analog input of drawing 15 of
page 40 is connected to the block of the analog output of drawing 16.
•
ASW1 Output
: The speed reference is taken from the exit of the Analog Switch 1 block (see section 5.6.11 on page68).
•
ASW2 Output
: The speed reference is taken from the exit of the Analog Switch 2 block (see section 5.6.11 on page68).
•
ASW3 Output
: The speed reference is taken from the exit of the Analog Switch 3 block (see section 5.6.11 on page68).
•
ASW4 Output
: The speed reference is taken from the exit of the Analog Switch 4 block (see section 5.6.11 on page68).
•
SumBlock Summ1
: The speed reference is taken from the “Summ1” output of the summing block (see paragraph 5.6.10 on
page 67).
•
SumBlock Summ2
: The speed reference is taken from the “Summ2” output of the summing block (see paragraph 5.6.10 on
page 67).
•
SumBlock Summ3
: The speed reference is taken from the “Summ3” output of the summing block (see paragraph 5.6.10 on
page 67).
