.
Overview of communication
With the upper host controller, which can be connected with 31 brushless amplifiers at the maximum via serial com-
munication conforming to RS485, enables the following:
①
Rewriting parameters
②
Browsing and clearing status and history of trip condition
③
Monitoring control status including present position, status, I/O, etc.
④
Start and stop of motor
⑤
Trip reset
[Advantage]
・
It is allowed to write parameters by one operation from host controller in startup of the machine.
・
Operating condition of the machine can be displayed, which improves serviceability.

Connection of communications line
Connect one host controller with more than one brushless amplifier via RS485 communication, and set the device
number of each brushless amplifier (Pr5A) at 81h (129)
—
9Fh (159).
Set the device number for the host as 01h (1)
—
1Fh (31).
<Note>
Device number is set at 81h (129) in default setting. When connecting more than one brushless amplifier via RS485,
be sure to change the device number beforehand with the digital keypad or communication software “PANATERM for
BL”.
