When terminal A3 is to be used for the frequency reference
• Voltage input
– Have you checked to make sure that DIP switch S4 inside the drive is at the analog input side?
– Have you checked to make sure that DIP switch S1-3 inside the drive is at the "V" side?
– Have H3-05 = 0, 1 [Terminal A3 Signal Level Select = 0-10V (LowLim=0), 0-10V (BipolRef)] been set?
– Has H3-06 = 0 [Terminal A3 Function Selection = Frequency Bias] been set?

• Current input
– Have you checked to make sure that DIP switch S4 inside the drive is at the analog input side?
– Have you checked to make sure that DIP switch S1-3 inside the drive is at the "I" side?
– Has H3-05 = 2, 3 [Terminal A3 Signal Level Select = 4-20mA, 0-20mA] been set?
– Has H3-06 = 0 [Terminal A3 Function Selection = Frequency Bias] been set?
Have you checked to make sure that the frequency reference reaches the desired minimum and maximum
values?
Check the following items if the desired values are not reached.
Gain adjustment: Set the maximum voltage and current values, then adjust the analog input gain until the
29
frequency reference reaches the desired 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 desired minimum value. (For terminal A1 input: H3-04, for terminal A2 input: H3-12, for
terminal A3 input: H3-08)
