Command Value
If the following settings are made in the PLC Setup, the inverter frequency
command value will be calculated automatically and set in A23 in the Auxiliary
Area. These settings are on the Inverter Positioning 0 Tab Page in the PLC
Setup.
• Power Supply Frequency for One Motor Revolution per Second (0.1-Hz
increments)
• Number of Encoder Pulses for One Motor Revolution
• Error Counter Cycle (x 4 ms)
The inverter frequency command value in A23 is accessed. The value is
stored in 0.01-Hz increments.
