G3 Parameter Settings
Profibus interface board communications are enabled by setting parameter
COMMUNICATION SELECTION in GROUP:COMMUNICATION SETTING PARAMETERS
to 2 (Profibus, Modbus, DeviceNet). None of the Tosline-F10 communication
parameter settings apply when using the Profibus interface. For more information on
methods for changing parameter settings, refer to the TOSHIBA G3 Operation
Manual.
The following is a list of the parameter settings that are required during setup to
enable Profibus communications:

any value other than
126 ∼ 255.
Note:
Although the INVERTER ID NUMBER parameter can be set from 0 to 255,
the allowable Profibus slave addresses range only from 0 to 125. Therefore,
if this parameter is set to a value from 126 to 255, the Profibus interface card
will trip “OPTION PCB ERROR” upon initialization. To correct this error, set
the INVERTER ID NUMBER parameter to a value from 0 to 125.
To implement any parameter changes in GROUP:COMMUNICATION SETTING
PARAMETERS, the drive must be reset after making the changes.
If the drive into which a Profibus communications interface board is installed trips
“OPTION PCB ERROR” for any reason during initialization or operation (for example,
if it becomes loose from its mounting connections), it is incapable of being reset via
the Profibus network. When this trip condition occurs, therefore, the drive can only
be reset locally via the panel or control terminal block.
If drive control (frequency command input, RUN/STOP, etc.) is to be performed via
the Profibus network, the following inverter parameters must also be set as shown:

FREQUENCY MODE SELECTION GROUP:UTILITY PARAMETERS

Of course, input data can always be monitored from the network regardless of the
settings of COMMAND MODE SELECTION and FREQUENCY MODE SELECTION. Also
note that if the COMMAND MODE SELECTION or FREQUENCY MODE SELECTION
parameters are changed while the drive is running, the change will not take effect
until the next time the drive is stopped.
