YASKAWA P1000 Quick Start Manual page 111

A 10 Vdc input is equivalent to a 200% frequency reference and 5 Vdc is equivalent to a 100% frequency reference. Since
the drive output is limited by the maximum frequency parameter (E1-04), the frequency reference will be equal to E1-04
above 5 Vdc.
• Gain H3-03 = 100%, bias H3-04 = -25%, terminal A1 as frequency reference input:
An input of 0 Vdc will be equivalent to a -25% frequency reference.
When parameter H3-01 = 0, the frequency reference is 0% between 0 and 2 Vdc input.
When parameter H3-01 = 1, the motor will rotate in reverse between -10 and 2 Vdc input.
