When you use terminal A2 for the frequency reference:
• Voltage input
– Set DIP Switch S1 on the drive to “V”.
– Set H3-09 = 0, 1 [Terminal A2 Signal Level Select = 0 to 10V (Lower Limit at 0), -10 to 10V (Bipolar Reference)].
– Set H3-10 = 0 [Terminal A2 Function Selection = Frequency Reference].
• Current input
– Set DIP Switch S1 on the drive to “I”.
– Set H3-09 = 2, 3 [Terminal A2 Signal Level Select = 4 to 20 mA, 0 to 20 mA].
– Set H3-10 = 0 [Terminal A2 Function Selection = Frequency Reference].
19
When you use terminal A3 for the frequency reference:
• Voltage input
– Set DIP Switch S4 on the drive to analog input side.
– 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].
20
Make sure that the frequency reference gets to the necessary minimum and maximum values.
Note:
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 and then adjust the analog input bias until the frequency reference is at the
desired minimum value.
(For terminal A1 input:H3-04, for terminal A2 input:H3-12, for terminal A3 input: H3-08)
