Even if SYNCMOD = 1 (synchronous comm.), SYNCMOD will be set to 0 for
asynchronous data transmission.
In the following case, a warning is generated and the command is ignored. Commands are also ignored in phase 2
(with no alarm).
•
If COM_MOD is set out of range: Data setting warning (A.94)
•
If SUBCMD is set to 1 in 17-byte data transmission: Data setting warning (A.94)
•
If SUBCMD is set to 1 for Ver. 1.0 (VER: 10H): Data setting warning (A.94)
•
If Bit6, Bit5, Bit4, Bit3, or Bit0 is set to 1: Data setting warning (A.94)
COM_TIM
In MECHATROLINK-I, COM_TIM = 2 the units for COM_TIM were 1 = 1 ms and transmission cycles were
fixed at 2 ms.
If COM_TIM ≠ 2: Data setting warning (A.94)

The DISCONNECT command releases the connection. The communication phase shifts to communication phase
1 after this command is completed.
After moving to phase 1, no check for transmission faults is executed. The command can be used in
communication phases 2 and 3.
If this command is received while in phase 2 or 3, the data for the control command to the Drive is cleared to 0,
and a fault reset command is carried out for the Drive.

The INV_CTL command is used to set the drive operation signals, speed references, and others. These bytes do
not need to be set every scan.
The settings are saved in the drive until the next data is received or until the power is turned OFF. For details on
operation signals, refer to
.
The speed reference and the output frequency drives can be selected with
