When Auto is selected, the drive automatically calculates the number of motor poles of
the machine from the settings in parameters 07 and 39. If either of these parameters are
adjusted for a special motor or to modify the V/f characteristic, the automatic calculation
may calculate the number of motor poles incorrectly. This would cause an incorrect slip
compensation to be applied and the rpm speed indication would be incorrect. Therefore,
the correct number of motor poles should be programmed manually.
Used to select the mode of operation of the serial port
AnSI ANSI EIA485 2 wire half duplex serial communications
rtu Modbus RTU protocol
FbUS Fieldbus protocol
When parameter 41 is set to FbUS, parameter 42 ‘baud rate’, is automatically set
to 19.2.
Used to select the comms port baud rate
Used to define the unique address for the drive for the serial interface. Any number in the
permitted range 0.0 to 24.7 which has a zero in it should not be used as these are used
in addressing groups of drives.
Indicates the version of software fitted to the drive.
