•
By external analog signal input terminals on the function of setting frequency multiplier effects.
•
If many inverters operation proportionally, take advantage of this function on the instructions of the
master inverter to the salve inverter for fine-tuning more effective.
•
After the setting frequency multiplier effects by the setting of P.185, then perform addition and
subtraction operations.
•
If P.185=0, the function is invalid.
For example: When the setting frequency is 50Hz, P.185=50% and external analog signal input for
0~10V.
In the diagram:
At 0V, the target frequency can be calculated by this formula: 50Hz - (50Hz×50%) = 25Hz
At 5V, the target frequency can be calculated by this formula: 50Hz - (50Hz×0%) = 50Hz
At 10V, the target frequency can be calculated by this formula: 50Hz + (50Hz×50%) = 75Hz
Note: 1. Seclection the 4-5 external analog signal (voltage or current) input terminals, please refer to
P.17
; the
frequency range of the external analog signal, please refer to
P.38
and
P.39
.
2. Proportion linkage signal input, please refer to
P.240
