■ Setting of parameter
●Selection of communication protocol () Shipment setting: 0 (TOSHIBA Inverter Protocol)
Protocol setting with all inverters (both master and slave inverters) engaged in inter-drive commu-
nications
0: Set the TOSHIBA Inverter Protocol.
* Inter-drive communications 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 inverter(transmission of frequency commands) : Master inverter (transmission of
output frequency signals)
- Setting to the slave inverters
Set the desired action on the slave side that will be needed when the master trips.
: Sets the frequency command value to 0Hz. (Output frequency is limited by low-limit frequency)
: Normal operation is continued
(If an output frequency is set on the master side, the output frequency of the master side be-
comes 0Hz due to tripping and the frequency of commands to the slave side becomes 0Hz.)
: Makes an emergency stop (“E” trip).
(The method to stop follows the setting in “Emergency stop selection ()”
*This parameter is validated after resetting the inverter or rebooting the power supply.
• Communication waiting time () ... Shipment setting =
- Setting to the master inverter
Set up more than 0.03 seconds as a transmitting interval on the master side to wait for the proc-
essing time on the slave side(= ).
● Speed setting mode selection () ... Shipment setting = : Built-in potentiometer
Designate a target of speed command input for the inverter to the parameter .
- Setting to the master inverter
Designate a number except for “: serial communication ” ( ≠).
- Setting to the slave inverters
Designate “: serial communication ” ( =).
