Communication Response Delay Time
Default: 2.0
Settings 0.0–200.0ms
Sets the response delay time after the AC motor drive receives a communication command as
shown in the following.
Communication Main Frequency
Default: 600.0
Settings 0.0–1500.0 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 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.
