I/O group I 1 [Filter time constant for V0 input] 10 0/9999 10
I 2 [V0 input minimum voltage] - 0/10 0 V
I 3 [Frequency corresponding to I2] - 0/400 0.0 Hz
I 4 [V0 input max voltage] - 0/10 10 V
I 5 [Frequency corresponding to I4] - 0/400 60.0 Hz
 Set Frq – [Frequency Mode] to 2.
 The set frequency can be monitored in 0.0- [Frequency Command].
 I 1 : [Filtering time constant for V0 input]
Effective for eliminating noise in the frequency setting circuit.
Increase the filter time constant if steady operation cannot be performed due to noise. A larger setting
results in slower response (t gets longer).
 I 2 - I 5 : [Min/Max input voltage and corresponding frequency setting]
The corresponding frequency to V0 input voltage is settable.
Example: When setting I 2 - [V0 input minimum voltage] = 2V, I 3- [Frequency corresponding to I 2]=
10Hz, I 4 - [V0 input max voltage] = 8V and I 5 - [Frequency corresponding to I 4]= 50Hz, the following
figure is shown.
