Example 1:
Par. 3-00 = “-Max - +Max”
Par. 3-03 “Max reference” = 1500 RPM
Reference send = 1500hex (5376 dec)
The output can be calculated as:
Example 2:
Par. 3-00 = “Min - Max”
Par. 3-02 “Min reference” = 100 RPM
Par. 3-03 “Max reference” = 1500 RPM
Reference send = 1500hex (5376 dec)
The output can be calculated as:
8.2.1. LED Behaviour Stopped Interbus Comm.
In case of stopped Interbus communication, a particular behaviour of the “FC bus” –LED can be observed. The behaviour and conditions are as follows:
•
Interbus communication is stopped by the Master
•
The Interbus option is powered-up while the frequency converter is powered off
• The “FC bus” LED is flashing, indicating baud-rate search
•
The frequency converter is powered-up
• The “FC bus” LED turns off, indicating baud-rate found and no FC-bus communication.
NB!
This might be interpreted as failing FC-bus communication, but in fact, the FC-bus comm. is inactive due to the stopped Interbus comm.
This is not a failure.
