Common Parameter Area Section 4-3
Data Details Set the allocations for the MECHATROLINK devices connected to the PCU.
Make the following settings using eight bits per axis for axes 1 to 16.
00 hex: Axis not used (no allocation).
40 hex: Axis allocated to the Servo Drive.
Up to 16 axes can be allocated for the CS1W/CJ1W-NCF71, up to 2 axes can
be allocated for the CS1W/CJ1W-NC271, and up to 4 axes can be allocated
for the CS1W/CJ1W-NC471. An error will occur if you allocate more axes than
your Unit supports.
Setting Example In this example, axes 1 to 3, axis 5, and axis 8 are allocated to the Servo
Drive. (The axis number corresponds to the station number for the MECHA-
TROLINK device.)

Data Details This parameter is used to make the settings for MECHATROLINK communi-
cations. For details on settings, refer to
6-2-3 MECHATROLINK Communica-
tions Settings .
Transfer Cycle
This parameter is used to set the cycle for sending and receiving data with
MECHATROLINK communications.
00: 1 ms (default setting)
01: 1 ms
05: 5 ms
02: 2 ms 06: 6 ms
03: 3 ms 07: 7 ms
04: 4 ms 08: 8 ms
A2 hex: 0.25 ms A5 hex: 0.5 ms
Communications Cycle
This parameter sets the cycle for refreshing data in the PCU and MECHA-
TROLINK device. The communications cycle is set in the Common Parame-
ters by setting the factor used to obtain integer multiples of the transfer cycle.
Set value: 00 to 20 hex
The default setting 00 is the same as when the cycle is set to 3. The commu-
nications cycle, however, is set as follows:
