V/f detach separation is generally used in applications such as induction heating, inverter power supply and
torque motor control.
If V/f separated control is selected, the output voltage can be set by parameter 03-14, or set communication can
be given by analog quantity, multi-step speed command, PLC, PID or communication. When a non-numeric
setting is selected, 100% of each setting corresponds to the rated voltage of the motor. When the percentage of
the output setting such as the analog quantity is negative, the set absolute value is used as the effective setting
value.
0.Digital setting (03-14):Voltage is set by 03-14.
1.AVI1
2.AVI2/ACI
Voltage is confirmed by analog input terminal.
4.Pulse setting(MI5)
The voltage reference is given by the terminal pulse. Pulse given signal specifications: voltage range 20V ~ 27V,
frequency range 0kHz ~ 100kHz.
5.Multi-step speed command
When the voltage source is a multi-speed command,set the 04 group and 05 group parameters to select the
correspondence between the given signal and the given voltage.
6. Simple PLC
When the voltage source is a simple PLC, you need to set 05 group of parameters to determine the given
output voltage.
7.PID
The output voltage is generated according to the PID closed loop. For details, see 10 group of PID introduction.
8.Communication setting
The voltage is given by the host computer through communication.
When the above voltage source is selected from 1 to 8, 0 to 100% corresponds to the output voltage 0V to the
rated voltage of the motor.

The V/f detach rise time refers to the time required for the output voltage to change from 0V to the rated voltage of
the motor. As shown in figure 5-5:
