Device
number
80ｈ(128)
81h(129)
Set the device number of motor in communi-
cation (Motor ID).
This value is the shaft number in communica-
tion.
80h (128) is the device number for setting
control data (such as control start) by one op-
eration to all connected motors. (No response
is made by motors.)
When the device number is set to 80h (128),
change of parameter and request for status are
ignored, therefore set to 81h (129) - 9Fh (159)
normally.

Communication response time is the shortest
time for setting transmission mode in RS485
bus for response after the motor has received
communication data. Actual data response
time depends on the type and data of order.

Protocol
timeout

Protocol timeout is the time allowed from re-
ception of a character code to reception of the
next one in communication. If normal charac-
ter code is not received within this time, com-
munication is timed out, and received data is
discarded. If timeout should continue to occur,
and the number of detections exceed the retry
times, the motor trips due to RS485 communi-
cation error.
Unit [seconds]
Change of parameters above is made effective when power is turned on.
・
Time required for data transmission per byte is calculated by the following formula. For example in the case of
9600 [bps], 8 bits, parity present (even number or odd number), and stop bit 1:
(1000/9600)
(1 + 8 + 1 + 1) = 1.14 [ms/byte]
Time is 4.58 [ms/byte] for 2400 [bps], and 2.29 [ms/byte] for 4800 [bps].
Note, however, actual communication time will be added time necessary for processing received command, and
necessary for switching between a line and transmission/reception control.
(2) Extension parameter (special command): 8103h - 81B0h
These are parameters to get motor status or to give commands to the motor. Refer to P.76 “Communication
command” for detail.
