Yaskawa E7L Drive Bypass - Manual (Page 170)

Programming 5 - 78
o3 Digital Operator Copy Function
o3-01 Copy Function Selection
The membrane over the Drive keypad also makes the keypad non-removable on Bypass units. In order to use the keypad copy
function on a Bypass unit - order a separate keypad, part number CDR001115 and obtain locally a standard CAT 5
Ethernet cable.
Note: The copy function is disabled when serial communication is active.
o3-02 Read Allowed Selection
The digital operator has parameter COPY capabilities via built in non-volatile memory. The digital operator can READ all of
the parameters in the Drive and store them for later WRITE back to the Drive or into a Drive with the same product code and
software number. In order to read the parameter values and store them in the digital operator, select o3-02= “1: Enabled”. If
you attempt to READ the data, which overwrites any previously stored data, without first setting o3-02= “1: Enabled”, you
will get a PrE error.
After setting o3-02= “1: Enabled”, it is possible to store parameter values in the digital operator by setting o3-01=1
(INV →OP READ).
A successful READ of the parameter values will display rEd.
An error may occur while saving the parameter values to the digital operator’s memory. If an error is displayed, press any key
to cancel the error display and return to parameter o3-01. To COPY parameter values into a Drive, set o3-01= “2: OP->INV
WRITE”. During the writing of the parameter values into the Drive the digital operator will display CPy.
An error may occur while writing the parameter values to the Drive. If an error is displayed, press any key to cancel the error
display and return to parameter o3-01.
It is possible to compare the parameter values stored in the digital operator with the parameter values currently in the Drive by
using the VERIFY function. This VERIFY function should not be confused with the “-VERIFY-“ that is displayed on the
digital operator when viewing the “Modified Constants” menu. To VERIFY the parameter values in the Drive as compared
with those stored in the digital operator, set o3-01= “3: OP<-->INV VERIFY”. During the comparing of the parameter values
into the Drive the digital operator will display uFy.
If all the parameter values stored in the digital operator do not match those programmed in the Drive, the digital operator
displays the following uYE.
