When combined speed control is adopted for frequency source, F206 is used to confirm the
relative object of the setting range for the secondary frequency.
F205 is to confirm the reference of the secondary frequency range. If it is relative to main
frequency, the range will change according to the change of main frequency X.
F207 Frequency source selecting
Setting range:
0: X;
1: X+Y;
2: X or Y (terminal switchover);
3: X or X+Y (terminal switchover);
4: Combination of stage speed and
analog
5: X-Y
6: Reserved
Mfr’s value: 0
Select the channel of setting the frequency. The frequency is given by combination of main
frequency X and secondary frequency Y.
When F207=0, the frequency is set by main frequency source.
When F207=1, X+Y, the frequency is set by adding main frequency source to secondary
frequency source. X or Y can be given by PID.
When F207=2, main frequency source and secondary frequency source can be switched over
by frequency source switching terminal.
When F207=3, main frequency given and adding frequency given(X+Y) can be switched over
by frequency source switching terminal. X or Y cannot be given by PID.
When F207=4, stage speed setting of main frequency source has priority over analog setting of
secondary frequency source (only suitable for F203=4 F204=1).
When F207=5, X-Y, the frequency is set by subtracting secondary frequency source from main
frequency source. If the frequency is set by main frequency or secondary frequency, PID speed
control cannot be selected.
Notes
When F203=4 and F204=1, the difference between F207=1 and F207=4 is that when F207=1,
frequency source selecting is the addition of stage speed and analog, when F207=4, frequency
source selecting is stage speed with stage speed and analog given at the same time. If stage
speed given is cancelled and analog given still exists, inverter will run by analog given.
Frequency given mode can be switched over by selecting F207. For example: switching PID
adjusting and normal speed control, switching stage speed and analog given, switching PID
adjusting and analog given, and so on.
The acceleration/deceleration time of stage speed is set by function code of corresponding
stage speed time. When combined speed control is adopted for frequency source, the
acceleration/deceleration time is set by F114 and F115.
The mode of automatic cycle speed control is unable to combine with other modes.
When F207=2 (main frequency source and secondary frequency source can be switched over
by terminals), if main frequency is not set to be under stage-speed control, secondary
frequency can be set to be under automatic cycle speed control (F204=5, F500=0). Through
the defined switchover terminal, the control mode (defined by X) and automatic cycle speed
control (defined by Y) can be freely switched.
If the settings of main frequency and secondary frequency are the same, only main frequency
will be valid.
