Digital Operator Copy Function Faults - Omron VARISPEED L7 Manual

Digital Operator Copy Function Faults

These faults can occur during the digital operator COPY function. When a fault occurs, the fault content is dis-
played on the operator. The fault or alarm contact output is not operated.

o3-01 was set to 1 to write parameter into the Digi-
PRE
tal Operator when the Operator was write-protected
(o3-02 = 0).
The data file read from the Inverter was of the
IFE
wrong size indicating corrupted data.
An attempted writing of the Inverter data to the
RDE
Digital Operator's EEPROM failed.
The Inverter type or software number was different
CPE
from the stored data in the digital operator
The capacity of the Inverter and the capacity of the
VAE
stored data in the Digital Operator are different.
The control method of the Inverter and the control
CRE
method of the stored data in the Digital Operator
are different.
A parameter setting written to the Inverter was dif-
CYE
ferent from the setting stored in the Digital Opera-
tor.
Upon completion of the COPY function, the
CSE
Inverter's data checksum was different to the digital
operator's data checksum.
The set value of the digital operator and the Inverter
VYE
do not match
Probable Causes Corrective Actions
Set o3-02 to enable writing parameters into the
Operator's memory.
Retry the READ command (o3-01 = 1).
Check the Digital Operator's cable.
Replace the Digital Operator.
A low Inverter voltage has been detected.
Retry the READ command (o3-01 = 1).
Replace the Digital Operator.
Use stored data of the same product (L7) and soft-
ware number (U1-14) only.
Use stored data for the same Inverter capacity only
(o2-04).
Use stored data for the same control
method (A1-02).
Retry the COPY function (o3-01 = 2)
Retry the COPY function (o3-01 = 2)
Retry the Verify function (o3-01 = 3)
