Using the PC Software — DOP Plus
During application development, using the
DOP Plus software is a great way to
configure your inverter. This package
works with several Hitachi inverter
families, providing these features:
• Automatic detection of inverter family
• Save parameter settings to disk
• Load parameters settings from disk
• Print all parameters and functions
• Compare inverter settings with disk file
• RS232/422 converter and cable included
• Built-in help screens for functions
• Automatic Quick Function Parameter
Select
• Runs on a PC with either Windows 3.1, Win95/98, or Windows NT
Initial setup is easy, using the 2-meter cable and RS232/422 converter as shown below.
The RS422 electrical characteristics are more noise-immune to electrical interference
from inverters and large motors. We recommend that you keep the communications
cable away from inverter power supply or motor wiring as a precaution.
When you connect the cable and go on-line with the DOP software, the inverter keypad
is disabled (except for the Stop/Reset key). When you go off-line or disconnect the
cable, the inverter keypad becomes fully enabled.
