„ Setting of parameter
●Protocol selection ( ,  ) Shipment setting: 0 (TOSHIBA)
Protocol setting with all inverters (both master and slave inverters) engaged in inter-drive commu-
nication
0: Set the TOSHIBA.
* Inter-drive communication are disabled when the MODBUS-RTU protocol is selected.
* This parameter is validated after resetting the inverter or rebooting the power supply.
● Setting of master and slave inverters for communication between inverters (setting of master and
slave) ( ,  ) ... Shipment setting = 
Assign one master inverter in the network. Other inverters should be the slave inverters.
*Specify only one inverter as the master. In case two or more inverters are designated for the
master inverter in the same network, data will collide.
- Setting to the master inverter
Set data desired for sending from the master side to the slave side.

: Master (sends a frequency command)
 : Master (sends an output frequency)
 : Master (sends a torque command)
 : Master (sends an output torque command)
- Setting to the slave inverters
Set the desired action on the slave side that will be needed when the master trips.
0 : Slave (issues a 0Hz command if something goes wrong with the master) (when f806 and
f826 are set to 3 and 4, respectively.))
(The output frequency is limited to the lower limit frequency.)
1 : Slave (continues operation if something goes wrong with the master)
Note: If the master inverter trips when an output frequency is specified for it, the operation fre-
quency of the slave inverters become 0Hz because tripping of the master inverter causes its
output frequency to drop to 0Hz.
2 : Slave (trips for emergency stop if something goes wrong with the master)
The way they make an emergency stop depends on the setting of f603 (emergency stop).
*This parameter is validated after resetting the inverter or rebooting the power supply.
• Send waiting time () ... Shipment setting = 
- Setting to the master inverter
Specify a waiting time if you want the master to issue commands to slaves with a given delay.
● Frequency setting mode selection 1 (fm0d) ･･･ Shipment setting = 2: RR/S4 input
Designate a target of speed command input for the inverter to the parameter .
- Setting to the master inverter
Select an option other than RS485 communication (fm0d≠5 or 6).
- Setting to the slave inverters
Select from between:
fm0d
=5: 2-wire RS485 communication input
fm0d =6: 4-wire RS485 communication input
