7.  EIII Parameter Settings 

Metasys N2 interface communications are enabled by setting parameter 

Opt

 in 

Gr.tr

to 2 (Metasys / Modbus / Tosline-F10).  No other Tosline-F10 communication 
parameter settings apply when using the Metasys N2 interface.  When using any 
communication interface on the EIII inverter, the frequency command and command 
input received from the network can be enabled by setting parameters 

FMOd

 and 

CMOd

, 

respectively, in 

Gr.Ut

 to 3.  For more information on methods for changing parameter 

settings, refer to the TOSHIBA EIII Operation Manual. 
 
The following is a list of the parameters settings that are required during setup to 
enable Metasys N2 communications:

As is the same with all other communication configuration parameters, the inverter 
must be reset after making the parameter changes described above in order for the 
changed settings to be enabled. 
 

IMPORTANT:

The standard factory setting for parameter

Ino

 is 

0

, which is reserved 

for Johnson Controls’ use.  If this parameter is not changed prior to 
enabling Metasys communications, the inverter will trip "

Err8

” 

(communication interface card error). 

 
If the EIII inverter into which a Metasys N2 communication option board is installed 
trips “

Err8

” (communication interface card error) for any reason during initialization or 

operation, it is incapable of being reset via the Metasys network.  When this trip 
condition occurs, therefore, the inverter can only be reset locally via the panel or 
control terminal block. 
 
If inverter control (frequency command input, RUN/STOP, etc.) is to be performed via 
setting Analog Output and Binary Output points from the N2 network, the following 
inverter parameters must also be set as shown:
