„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
