6.4 Analog signals for frequency setting
6.4.1 Setting frequency command characteristics
H : Analog input/logic input function selection
H : VI/S3 reference point 1 setting (%)
H : VI/S3 reference point 2 setting (%)
H : V1/S3 point 1 frequency (Hz)
H : V1/S3 point 2 frequency (Hz)
• Function
By changing the setting of H, the function of the VI/S3 terminal can be switched
between 0~(5)10Vdc voltage input and 4~20mAdc current input.
The H to H parameters are used to adjust the output frequency according to the
analog signal (voltage: 0~(5)10Vdc, current: 4~20mAdc) from an external device.
