11-8-2 Umotor sinusoidal
no: The equipment tries to hold the motor
voltage, until possible even on the expense
of the sinusoidal form.
yes: Depending on the DC voltage, the frequency
converter can only compensate the motor
voltage until it remains sinusoidal.

CAN bus
At master/slave relation, the slave devices receive the operation commands from the master.
The contents of the CAN message – depending on the application – can be set.

Explanations to the CAN bus
At selecting „master” the CAN bus operates as output, and sends data to the connected „slave” device or devices!
At selecting „slave” the CAN bus operates as input, and receives data from the connected „master” device!
In case of more independent master/slave relations, the devices can be connected through RS 485 line. Thus the
devices can be operated from a common terminal or computer. In such case, the identifier of each device must be
different!
Features and capabilities of the master/slave connection
• control
The slave device (devices) uses the frequency reference signal received from the master device, and it has
possibility for changing the frequency ratio (e.g. because of different number of poles) (menu 4-30-1)
slave settings: control,
control reference signal source: CAN,
CAN bus: slave,

• regulation to rotation speed

IRE data
The master and the slave(s) run at the same rotation speed from the moment of start on.
