MECHATROLINK Settings
Section 6-2
Setting the Transfer Cycle and Communications Cycle
The transfer cycle and communications cycle are set as Common Parameters
in the PCU. Set the PCU's transfer cycle and communications cycle according
to the number of connected MECHATROLINK devices so that the set values
are not lower than the values shown in the following table.
Note
Make sure that all of the axis number settings (station numbers of
the MECHATROLINK devices) are set to values equal to or less
than the number of connected devices for the transfer cycle. Here,
the number of connected MECHATROLINK devices is not the ac-
tual number of MECHATROLINK devices connected, but the high-
est registered axis number. For example, when using
MECHATROLINK devices for axis number 9 or higher, the transfer
cycle must be at least 2 ms even if less than nine devices are con-
nected. If the set value for the transfer cycle is smaller than the
number of connected devices or the axis number settings, a Trans-
fer Cycle Setting Error (Unit error code: 0027) will occur when
CONNECT is executed.
For the communications cycle, set the multiplier of the transfer cycle set value
so that the value is not lower than the values shown in the following table.
For example, if up to 3 Servo Drives (axis number 1 to 3) equipped with FNY-
NS115 MECHATROLINK-II I/F Unit are connected to the PCU, either set the
transfer cycle to 0.5 ms min. and the communications cycle set value to 2
(multiplier) or higher, or set the transfer cycle to 1.0 ms min. and the communi-
cations cycle set value to 1 (multiplier) or higher.
