1. Interface Board Installation / Removal
The Modbus Communications Option ROM enclosed with the Modbus kit is
compatible only with G3 inverters with V120 or later main software. An error will occur
if the option ROM is installed in an inverter with pre-V120 main software. The main
software version number is printed on the CPU package (IC1) on the control board.
Additionally, this version number can be read from inverter memory by displaying the
parameter CPU VERSION in GROUP:UTILITY PARAMETERS. If you are unsure of
the software version of your inverter, please contact Toshiba International Corporation
for more information.
The Modbus option ROM version number is printed on the label attached to the ROM.
The option ROM version number can also be read from the inverter’s memory and
displayed on the LCD panel after initialization by displaying the parameter ROM
VERSION in GROUP:UTILITY PARAMETERS. The option ROM version number
replaces the standard ROM version number after installation/initialization.
IMPORTANT NOTE: The option ROM included with the Modbus interface kit
is for installation into G3 230V/460V units only. Do not install the option ROM into any
other inverter unit (such as H3, E3, or G3 600V units). All inverter units other than the
G3 230V/460V series are shipped from the factory with full communications capability,
and installation of the option ROM may cause incorrect operation or inverter damage.
1.1 Before Installation
All parameters will be automatically reset to the factory default values after the option
ROM is installed in the inverter. If it is desired to retain the current parameter settings,
the user should access the user-changed parameter group to display and record all
the parameters and setting values that have been changed from factory defaults.
Even if the current settings are saved to non-volatile memory by setting the
STANDARD SETTING MODE SELECTION parameter in GROUP:UTILITY
PARAMETERS to 5
*
, they will be erased from memory during initialization of the option
ROM.
• Setting the standard mode selection parameter will be referred to in this manual as
performing a TYPE X RESET, where X is the parameter setting value.
1.2 Installation Procedure
Installation of the TOSHIBA Modbus option ROM and interface board into a
TOSVERT-130 G3 inverter should only be performed by a qualified technician familiar
with the maintenance and operation of the G3. To install the option ROM and interface
board, complete the following steps:
1. Record the option ROM version number located on the label of the option ROM in
the following box. The option ROM version is the number immediately following
the “V” on the ROM label. For example, if the label indicates “V6401”, the option
