◆ Password Settings: A1-04, A1-05

The user can set a password in parameter A1-05 to restrict access to the converter. The password must be entered to
A1-04 to unlock parameter access (i.e., parameter setting A1-04 must match the value programmed into A1-05). The
following parameters cannot be viewed or edited until the value entered to A1-04 correctly matches the value set to
A1-05: A1-01, A1-03, and A2-01 through A2-33.
Note: Parameter A1-05 is hidden from view. To display A1-05, access parameter A1-04 and press
◆ Copy Function
Parameter settings can be copied to another converter to simplify parameter restoration or multiple converter setup. The
converter supports the following copy options:
• LCD Operator (standard in all models)
The LCD operator used to operate the converter supports copying, importing, and verifying parameter settings. Refer to
o3: Copy Function on page 188
• LED Operator
The optional LED operator also supports copying, importing, and verifying parameter settings. Refer to the manual
supplied with the LED operator for instructions.
• USB Copy Unit and CopyUnitManager
The copy unit is an external option connected to the converter to copy parameter settings from one converter and save
those settings to another converter. Refer to the manual supplied with the USB Copy Unit for instructions.
Note: Connect the USB Copy Unit to the RS-422/RS-485 communication port on the converter.
CopyUnitManager is a PC software tool. It allows the user to load parameter settings from the Copy Unit onto a PC, or
from the PC onto a Copy Unit. This is useful when managing parameters for various converters or applications. Refer to
the manual supplied with CopyUnitManager for instructions.
Copying Procedure for the LCD Operator
■
The LCD operator can perform the following operations by changing the o3-01(Copy Function Selection) parameter in
the converter.
Read (o3-01 = 1)
Copies all parameters from the converter to the LCD operator.
Note: There is a limit to the number of read operations that you can perform from the LCD operator. As a guide, do not perform more
than 100,000 read operations.
