5.
3-02 Minimum Reference
. Set minimum internal
frequency converter reference to 0 Hz. (This sets
the minimum frequency converter speed at 0 Hz.)
Figure 5.4
6.
3-03 Maximum Reference
. Set maximum internal
frequency converter reference to 60 Hz. (This sets
the maximum frequency converter speed at 60
Hz. Note that 50/60 Hz is a regional variation.)
Figure 5.5
7.
6-10 Terminal 53 Low Voltage
. Set minimum
external voltage reference on Terminal 53 at 0 V.
(This sets the minimum input signal at 0 V.)
Figure 5.6
8.
6-11 Terminal 53 High Voltage
. Set maximum
external voltage reference on Terminal 53 at 10 V.
(This sets the maximum input signal at 10 V.)
Figure 5.7
9.
6-14 Terminal 53 Low Ref./Feedb. Value
. Set
minimum speed reference on Terminal 53 at 20
Hz. (This tells the frequency converter that the
minimum voltage received on Terminal 53 (0 V)
equals 20 Hz output.)
Figure 5.8
10.
6-15 Terminal 53 High Ref./Feedb. Value
. Set
maximum speed reference on Terminal 53 at 50
Hz. (This tells the frequency converter that the
maximum voltage received on Terminal 53 (10 V)
equals 50 Hz output.)
Figure 5.9
With an external device providing a 0-10 V control signal
connected to frequency converter terminal 53, the system
is now ready for operation. Note that the scroll bar on the
right in the last illustration of the display is at the bottom,
indicating the procedure is complete.
Figure 5.10
shows the wiring connections used to enable
this set up.
