You can set operating frequency by simultaneously using two methods of frequency setting. Main speed is used to
set the operating frequency, and the auxiliary speed can be used for precise adjustment during main speed
frequency. For example, let’s assume that the inverter has been set as in the table above. During operation at 30.00
Hz with Keypad-1 the main speed, if you supply voltage of -10~+10V to V1 terminal and set the gain at 5%
(variables between IN-01 ~ IN-16 are the initial values and IN-06 V1 Polarity is set as Bipolar), precise adjustment is
possible up to 33.00~27.00 Hz.
BAS-01 AUX Ref Src : selects the type of input to be used as auxiliary speed.
Setting Type Function
0 None No auxiliary speed motion
1 V1
Selects the voltage input terminal of the control terminal block as the auxiliary
speed.
2 I1 Selects the current input as the auxiliary speed.
3 V2 Selects the voltage input of the extended IO option board as the auxiliary speed.
4 I2 Selects the current input of the extended IO option board as the auxiliary speed.
BAS-02 Aux Calc Type : The reflection ratio of the main speed can be set by four operations after setting the amount
of the auxiliary speed as gain (BAS-03 Aux Ref Gain).
