The gateway mode performs communications processing to relay data from a drive equipped with the
communication option to multiple drives not equipped with the communication option via the internal RS-485
communication function. This enables up to a maximum of 5 drives to be connected via fieldbus communication
using only one communication option. The following commands and responses are exchanged 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 (running, faults)
• Reading and writing parameters
• Reading monitors
Note:
• Do not mount the communication option in slave drives when using the gateway mode.
• Doing so may disrupt synchronization of drive commands and responses.
• Response speed using the communication option is slower than when using point-to-point communications.
• Make sure H5-03 [Communication Parity Selection] is set to the same value on both the master drive and slave drives.
The following example illustrates the parameter settings when connecting four slave drives.

*1 Set the number of connected slave drives.
*2 Make sure the communications speed and communications parity are set to the same value on both the master drive and slave drives.
*3 Do not change the value of H5-06 from the default value to correctly detect the response timeout.
*4 Set H5-09 to a value of at least 0.9 seconds. When H5-09 < 0.9, CE will be detected before the response timeout is detected.
*5 Set the Run command and frequency reference source on slave drives to MEMOBUS/Modbus communications.
