• 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 [Max Output Frequency] will limit the drive output and the frequency
reference will be 100%.
• When you input a 0 V signal, the frequency reference will be -25%.
• When H3-01 = 0 [AI1 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 [0 to +10 V (Without Lower Limit)]
– When you input a 0 V to 2 V signal, it enables signals of positive and negative polarities and the motor
rotates in reverse.
