îš‹ Machine Data Copy Function Faults
These faults can occur during the machine data (encoder) COPY function. When a fault occurs, the fault con-
tent is displayed on the operator. The fault or alarm contact output is not operated.

Probable Causes Corrective Actions
WRITE from
inverter to
encoder
ERE
DATA ERROR
A write to encoder command could not be
performed since the drive is in UV (under
voltage) condition.
Make sure that no fault and no alarm is
active and retry.
COPY from
Encoder to
Inverter
EDE
WRITE IMPOSSIBLE
The write to encoder command is prohibited.
Set parameter F1-26 to 1 to permit a write to
encoder command.
EIF
WRITE DATA ERROR
A communication error occurred during the
write to encoder process.
Retry the write to encoder command.
ECE
COPY ERROR
A read to encoder command could not be
performed since the drive is in UV (under
voltage) condition.
Make sure that no fault and no alarm is
active and retry.
EPE
ID MISMATCH
The data in the encoder do not fit to the L7Z
data format.
-
ECS
SUM CHECK ERROR
The check sum of the data, which were writ-
ten into the inverter is wrong.
Retry the COPY command.
VERFIY
EVE
VERIFY ERROR
The data in the encoder and inverter data do
not match.
