d2-14
Voltage digital setting for V/F separation
Default
0 V
Setting Range
0 V ~ rated motor voltage
V/F separation is generally applicable to these sites, such as induction heating, inverse power supply and motor
torque control.
If V/F separated control is enabled, the output voltage can be set in d2-14 or by analog, Multi-function, simple
PLC, PID or communication. If you set the output voltage by means of non-digital setting, 100% of the setting
corresponds to the rated motor voltage. If a negative percentage is set, its absolute value is used as the effective
value.
0: Digital setting (d2-14)
The output voltage is set directly in d2-13.
1: AI1;
2: AI2;
3: AI3
The output voltage is set by analog input terminals.
4: Pulse setting (HDI)
The output voltage is set by pulses of the terminal HDI.
Pulse setting specification: voltage range 9V~30 V, frequency range 0kHz~100 kHz
5: Multi-function
6: Simple PLC
If the voltage source is simple PLC mode, parameters in group FC must be set to determine the setting output
voltage.
7: PID
The output voltage is generated based on PID closed loop. For details, see the description of PID in group C0.
8: Communication setting
The output voltage is set by the host computer by means of communication.
The voltage source for V/F separation is selected in the similar way to the frequency source selection. For details,
see b0-03 (main frequency source X specification). 100.0% of the setting in each mode corresponds to the rated
motor voltage. If the corresponding value is negative, its absolute value is used.
d2-15
Voltage rise time of V/F separation
Default
0.0s
Setting Range
0.0s~1000.0s
Note: It indicates the time for the voltage rising from 0 V ~ rated motor
voltage.
d2-15 indicates the time required for the output voltage to rise from 0 V to the rated motor voltage shown as t1 in
the following figure.
