When terminal A3 is used for the frequency reference:
• Voltage input
– Set DIP Switch S4 on the drive to analog input side.
– Set DIP Switch S1-3 on the drive to “V”.
– Set H3-05 = 0, 1 [Terminal A3 Signal Level Select = 0 to 10V (Lower Limit at 0), -10 to +10V (Bipolar
Reference)].
– Set H3-06 = 0 [Terminal A3 Function Selection = Frequency Reference].
• Current input
– Set DIP Switch S4 on the drive to analog input side.
– Set DIP Switch S1-3 on the drive to “I”.
– Set H3-05 = 2, 3 [Terminal A3 Signal Level Select = 4 to 20 mA, 0 to 20 mA].
– Set H3-06 = 0 [Terminal A3 Function Selection = Frequency Reference].

Make sure that the frequency reference reaches the necessary minimum and maximum values.
If drive operation is incorrect, make these adjustments:
Gain adjustment: Set the maximum voltage and current values, then adjust the analog input gain until the
frequency reference reaches the necessary value. (For terminal A1 input: H3-03, for terminal A2 input: H3-11,
for terminal A3 input: H3-07)
Bias adjustment: Set the maximum voltage/current values, then adjust the analog input bias until the frequency
reference reaches the necessary minimum value. (For terminal A1 input: H3-04, for terminal A2 input: H3-12,
for terminal A3 input: H3-08)
