Gateway Mode processes communications through internal the RS-485 communication function to relay data
from a drive that has the communication option to more than one drive that does not have the communication
option. This function lets you use fieldbus communication to connect a maximum of 5 drives with only one
communication option. The drive sends these commands and responses between the controller (Host device),
master drive (Drive 0), and the slave drives (Drive 1 to Drive 4).
• Commands: Run command and frequency reference
• Output frequency and drive status (during run, faults)
• Read and write parameters
• Read monitors
NOTICE: When you use Gateway Mode, do not install the communication option in slave drives. Failure to obey can cause
problems with synchronization of drive commands and responses.
Note:
• Response speed with the communication option is slower than with point-to-point communications.
• Set H5-03 [Communication Parity Selection] to the same value on the master drive and slave drives.
Table 12.36 shows the parameter settings when you connect 4 slave drives:

*1 Set the number of connected slave drives.
*2 Make sure that you set the communications speed and communications parity to the same value on the master drive and slave drives.
*3 To correctly detect the response timeout, do not change the value of H5-06 from the default value.
*4 Set H5-09 ≥ 0.9 s. When H5-09 < 0.9, the drive will detect CE before it detects a response timeout.
*5 Set the Run command and frequency reference source on slave drives to Modbus communications.
