Speed ref 1
1st reference value for the speed. The value to be entered depends on the factor function.
Speed ref 1 (%)
1st speed reference value as a percentage of the
Speed base value
Speed ref 2
2nd reference value for the speed. The value to be entered depends on the factor function.
Speed ref 2 (%)
2nd speed reference value as a percentage of the
Speed base value
Speed ref (rpm)
Total speed reference value in rpm.
Speed ref (d)
Total speed reference value in the dimension specified by the factor function.
Speed ref (%)
Total speed reference value as a percentage of the
Speed base value
.
The total speed reference value consists of the signed addition of
Speed ref 1
and
Speed ref 2
.
n
ote
:
Speed base value cannot exceed 8192 rpm.
Example 1:
Speed ref 1
= + 50 %
Speed ref 2
= + 30 %
Speed ref
= 50 % + 30 % = 80 %
Example 2:
Speed ref 1
= + 40 %
Speed ref 2
= - 60 %
Speed ref
= 40 % - 60 % = - 20 %
0 ... 10 V, 0 ... 20 mA and 4 ... 20 mA signals can be used when setting the reference value via terminals. The
speed reference value has an upper and a lower limit.
If the ramp is selected,
(Enable ramp
parameter= Enabled), the reference value input
Speed ref 1
is automati
-
cally linked with the ramp output.
6.4.3 Torque current reference (T current ref)
INPUT VARIABLES
T current ref
[39]
T current ref 1 [%]
[40]
T current ref 2 [%]
The current reference value is proportional to the armature current of the motor and determines the torque, the
polarity determines the torque direction. For most applications
T current Ref
comes from the speed regulator
output.
T current ref 2
can also be used as a correction value.
