Mfai Setting Value - YASKAWA HV600 Manual

Adds the offset value for the analog input value. For voltage input, this parameter will set the offset when a signal of 0
V is input. For current input, this parameter will set the offset when a signal of 4 mA [H3-09 = 2] or 0 mA [H3-09 =
3] is input.

0: Frequency Reference
Setting Value Function
0 Frequency Reference
• You can copy the configuration to more than one of the analog input terminals A1 and A2. When you set more than
one analog input terminal with the master frequency reference, the sum value becomes the frequency bias.
• If you use this function to set the analog input value as the master frequency reference, set b1-01 = 1 [Frequency
Reference Selection 1 = Analog Input]. This setting value is the default value for terminals A1 and A2.
• The frequency reference is the sum of the input values for terminals A1 and A2 when you use them at the same
time. For example, when you input a 20% bias to terminal A2 and input a frequency reference of 50% from
terminal A1, the calculated frequency reference will be 70% of the maximum output frequency.
