Table 5-109: Copy Function Parameter Settings
The keypad has parameter COPY capabilities via built-in non-volatile memory. The keypad can READ all of the
parameters in the VFD and store them for later, and then WRITE back to the VFD or into a VFD with the same product
code and software number. In order to read the parameter values and store them into the keypad, select O04-02 = 1
(Enabled). If you attempt to READ the data, which overwrites any previously stored data, without first setting O04-02 =
“1: Enabled,” you will get the following error:
After setting O04-02 = 1 (Enabled), it is possible to store parameter values in the
keypad
by setting O04-01 = 1
(INV
→ OP READ). A successful READ of the parameter values will display:
An error may occur while saving the parameter values to the
keypad
’s memory. If an error is displayed, press any
key to cancel the error display and return to parameter O04-01. Error displays and their meanings are covered in
Chapter 6: Troubleshooting of Copy function Related Faults. To COPY the parameter values into a VFD, set O04-
01 = 2 (OP
→ INV WRITE). During the writing of the parameter values into the VFD, the
keypad
will display:
