Communication Main Frequency
Settings
 When you set Pr. 00-20 to 1 (RS-485 serial communication), the AC motor drive saves the last
frequency command into Pr. 09-10 when there is abnormal power off or momentary power loss.
After the drive reboots when power is restored, it checks the frequency in Pr. 09-10 if there is no
new frequency command is input. When a frequency command of RS-485 changes (the
frequency command source must be set as Modbus), this parameter also changes.
