gain setting
adjusted
• H3-02 = 0 [Terminal A1 Function
Selection = Frequency Reference]
• H3-03: 200.0 [Terminal A1 Gain
Setting = 200%]
• H3-04 = 0.0 [Terminal A1 Bias
Setting = 0.0%]
• When you input a 10 V signal, the frequency reference will be 200%.
• When you input a 5 V signal, the frequency reference will be 100%.
When you input a 5 V or more signal, E1-04 [Maximum Output Frequency] will limit the drive output and the
frequency reference will be 100%.

•
H3-02 = 0 [Frequency Reference]
• H3-03 = 100.0 [100.0%]
•
H3-04 = -25.0 [-25.0%]
•
When you input a 0 V signal, the frequency reference will be -25%.
• When H3-01 = 0 [Terminal A1 Signal Level Select = 0 to 10V (Lower Limit at 0)] :
– When you input a 0 V to 2 V signal, the frequency reference will be 0%.
–
When you input a 2 V to 10 V signal, the frequency reference will be 0% to 100%.
• When H3-01 = 1 [-10 to +10V (Bipolar Reference)] :
– When you input a 0 V to 2 V signal, it enables signals of positive and negative polarities and the motor rotates in
reverse.

MEMOBUS/Modbus Multi-Function AI1 to 3 Function Selection
Let the MFAI function be assigned to MEMOBUS/Modbus register 15C1 to 15C3 (Hex.) [Mbus Reg 15C1h through
15C3h Input Function] . Use H3-40 to H3-42 [Mbus Reg 15C1h through 15C3h Input Function] to set the function
and use H3-43 [Mbus Reg Inputs FilterTime Const] to set the input filter.
