G3. Not all functions may be accessible, however, in other units. These exceptions will be noted where applicable. Also, use of this interface in other Toshiba 3-series drives may require the use of an additional plug-in communications option ROM. For more information regarding the required combinations of adjustable speed drives, interface boards and option ROMs, please contact your local distributor or Toshiba International Corporation.
Usage Precautions Operating Environment • Please use the communications interface only when the ambient temperature of the inverter unit into which the interface is installed is within the following specified temperature limits: Operation: -10 ∼ +40°C (+14 ∼ +104°F) -25 ∼ +65°C (-13 ∼ +149°F) Storage: •...

If the inverter unit does not appear to power up, or does not function properly, immediately turn power OFF. Repeat steps 1 ∼ 3 to remove all power from the inverter. Then, verify all connections. Contact Toshiba International Corporation for assistance if the problem persists.
1.2 Removal Procedure Removal of the N2 interface board from a EIII inverter should only be performed by a qualified technician familiar with the maintenance and operation of the EIII. In order to protect the interface board connector’s reliability, do not repeatedly connect and disconnect the interface board.

2. Grounding Grounding is of particular importance for reliable, stable operation. Communication system characteristics may vary from system to system, depending on the system environment and grounding method used. A ground connection with an impedance of less than 100Ω should be used. Please be sure to consider the following points for making proper ground connections: Grounding method checkpoints 1.
4. Maintenance And Inspection Preventive maintenance and inspection is required to maintain the Metasys N2 communications interface in its optimal condition, and to ensure a long operational lifetime. Depending on usage and operating conditions, perform a periodic inspection once every three to six months. Before starting inspections, always turn off all power supplies to the inverter unit, and wait at least five minutes after the inverter’s “CHARGE”...
The EIII Metasys N2 communications interface kit is covered under warranty for a period of 12 months from the date of installation, but not to exceed 18 months from the date of shipment from the factory. For further warranty or service information, please contact Toshiba International Corporation.
6. N2 Interface Configuration 6.1 N2 Network Connections Each EIII Metasys N2 interface board can be directly connected to the N2 bus by using twisted-pair cable connected as shown in Figure 4. Connect the N2+ wire to terminal “A”, the N2- wire to terminal “B”, and the cable shield to terminal “SHIELD” on the interface board’s TB1 terminal block.

8.3 Individual Object Descriptions This section gives a brief overview of each object, including any notable behavior or settings. For those parameters outlined here that directly map to internal EIII configuration parameters, refer to the EIII Operation Manual for further information regarding their usage or behavior.
8.3.2 Binary Input Objects BI #1 ..Indicates whether the inverter is running or stopped. BI #2 ..Indicates whether the inverter is running in the forward or reverse direction. BI #3 ..Indicates whether the inverter is currently using acceleration time #1 and deceleration time #1 or acceleration time #2 and deceleration time #2 when accelerating and decelerating.
8.3.3 Analog Output Objects IMPORTANT: Most of the AO objects detailed in this section map directly to EIII configuration parameters (parameters accessible via the EIII’s keypad). When these parameters are changed (from either the keypad or N2 network), they are stored in the EIII’s non-volatile EEPROM.

Note that the actual internal frequency command will be limited by the upper limit frequency (parameter UL in Gr.F). If the EIII was running at the time of the communications loss, it will then accelerate to and continuously run at the upper limit frequency;...
8.3.4 Binary Output Objects IMPORTANT: BO #9 and BO #10 map directly to EIII configuration parameters (parameters accessible via the EIII’s keypad). When these parameters are changed (from either the keypad or N2 network), they are stored in the EIII’s non-volatile EEPROM.
