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.

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.
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
- 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
fm0d
=5: 2-wire RS485 communication input
fm0d
=6: 4-wire RS485 communication input
