Chapter 12 Description of Parameter SettingsME300
12.1-09-12
Communication Main Frequency
Default: 60.00
Settings 0.00–599.00 Hz
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 no new
Frequency command is input. When a Frequency command of 485 changes (the Frequency
command source must be set as Modbus), this parameter also changes.
