7 Other Functions
*1. 07 (LAD frequency) represents the frequency commanded by the inverter and is equivalent of the Output Fre-
quency Monitor (d001) value. 00 (Output frequency) represents a frequency value that takes into account the
aspects of vector control compensation (such as sensorless vector control) and even stabilization control.
When set to 00 (Output frequency), the parameter may produce an output that appears to be unstable at low
speeds, for example, when decelerating due to the overload limit function. In this case, set it to 07 (LAD fre-
quency) to obtain a stable output.
*2. Setting the Pulse Train Input EA Selection (P003) to 01 (Feedback pulse) causes the inverter to output the
frequency displayed in the Real Frequency Monitor (d008).
*3. This setting is enabled only when the 1st/2nd Control Method (A044/A244) is set to 03 (Sensorless vector con-
trol). When A044/A244 is not set to 03, the inverter does not produce output because it remains at 0 V.
*4. When the Frequency Conversion Coefficient (b086) is set, the digital output frequency outputs a converted val-
ue. Refer to 7-1-7 Output Frequency Monitor (After Conversion) [d007] on page 7-6.

EO Gain Setting
You can set the output gain in the EO Gain Setting (C105) when the EO Selection (C027) is set to 00 to
02, 04 to 07, 10, or 12 (settings with PWM output).
When C027 is set to 08 (Digital current monitor), set the reference current value for the output pulses in
the Digital Current Monitor Reference Value (C030). The output will be made in proportion to this value,
so that the current value set in C030 produces an output frequency of 1440 Hz.
When C027 is set to 15 (Pulse train input monitor), you can set the output gain in the Pulse Train Out-
put EO Scale (C047) (to obtain an output of Input value  C047).
