Setting frequency command characteristics

Output frequency is adjusted in relation to frequency command according to external analog signals.
Analog signal is  set to 0: 0 to 10Vdc, 1: 4 to 20mAdc, 3: 0 to 5Vdc.
 analog input filter is effective for eliminating noise from frequency setting circuit. Increase if
operation cannot be done because noise effects stability.
