MELSERVO-J4, J3 Series
For details of the MELSERVO-J4, J3 Series, refer to
the following manual.
See the technical manual for the MELSERVO-
J4, J3 Series servo amplifiers.
Parameters of MELSERVO-J4, J3 Series
Enter the parameters of the MELSERVO-J4, J3 Series.
*1 Avoid duplication of the station No. with any of the other
axes.
*2 Specify the same transmission speed as that of the GOT.
For the transmission speed setting on the GOT side, refer to
the following.
16.4.1 Setting communication interface
(Communication settings)
POINTPOINTPOINT
(1) Parameter setting
Set the parameter at the pushbutton switch
provided on the operation section of the servo
amplifier or setup software.
(2) When changing the parameter
Turn off then on the servo amplifier to be effective
the new parameter.
16.5.4 Station number setting
Set each station number so that no station number
overlaps.
The station number can be set without regard to the cable
connection order. There is no problem even if station
numbers are not consecutive.
(1) Direct specification
When setting the device, specify the station number of
the servo amplifier of which data is to be changed.
(2) Indirect specification
When setting the device, indirectly specify the station
number of the inverter of which data is to be changed
using the 16-bit GOT internal data register (GD10 to
GD25).
When specifying the station No. from 100 to 115 on GT
Designer3,the value of GD10 to GD25 compatible to
the station No.specification will be the station No.of the
servo amplifier.
(3) All station specification
Target station differs depending on write-in operation or
read-out operation.
• For write-in operation, all station will be a target.
• For read-out operation, only one station will be a
target.
