Setting of Terminal A1 Frequency Reference
Frequency
reference with the
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 Vor more signal, E1-04 [Maximum Output Frequency] will limit the drive output and the
frequency reference will be 100%.
Frequency
reference with the
negative number
bias set
• 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.
