10.1 Specifications for Communications with Connected Inverters
The following table provides the specifications required when connecting inverters through MECHATROLINK.
* 1. The maximum number of connectable inverters in MECHATROLINK-II 32-byte mode can be obtained by the fol-
lowing equation.
Transmission cycle 2 ms: 21
− C2 Message (with: 1, none: 0) − Number of retries to slaves
Transmission cycle 1 ms: 9 − C2 Message (with: 1, none: 0) − Number of retries to slaves
Setting range of number of retry to slaves is 0 to 7.
If the result of the above equation is 16 or greater, the maximum number of connectable inverters is 16.
* 2. The maximum number of connectable inverters in MECHATROLINK-II 17-byte mode can be obtained by the fol-
lowing equation.
Transmission cycle 1 ms: 15
− C2 Message (with: 1, none: 0) − Number of retries to slaves
Setting range of number of retries to slaves is 0 to 7.
