 Control by PC (Computer Link)
When using the RS-485 serial communication interface, you must specify each drive’s
communication address in Pr.09-00. The computer then implements control using the drives’
individual addresses.
 Modbus ASCII (American Standard Code for Information Interchange): Each byte of data is the
combination of two ASCII characters. For example, one byte of data: 64 Hex, shown as ‘64’ in
ASCII, consists of ‘6’ (36Hex) and ‘4’ (34Hex).

Communication Response Delay Time
Default: 2.0
Settings
0.0–200.0 ms
 If the host controller does not finish the transmitting/receiving process, you can use this
parameter to set the response delay time after the AC motor drive receives communication
command as shown in the following picture.
09-10
Communication Main Frequency
Default: 60.00
Settings
0.00–599.00 Hz
 When you set Pr.00-20 to 1 (RS-485 communication input), the AC motor drive saves the last
Frequency command into Pr.09-10 when there is abnormal power off or momentary power loss.
When power is restored, the AC motor drive operates with the frequency in Pr.09-10 if there is
no new Frequency command input. When a Frequency command of 485 changes (the
Frequency command source must be set as Modbus), this parameter also changes.
