correction Assumed cause Correction Prevention
An EtherCAT slave that is allocated to
an axis was disconnected or replaced
while the Servo was ON. Reconnect the EtherCAT slave that is
allocated to the axis to the network. Turn OFF the Servo before you dis-
connect or replace a slave.

Meaning The target position after the interrupt input was received for the MC_MoveFeed (Interrupt Feeding) instruction over-
flowed or underflowed.

System-defined
variables Variable Data type Name
_MC_AX[*].MFaultLvl.Active BOOL Axis Minor Fault Occurrence
Cause and
correction Assumed cause Correction Prevention
The target position after the interrupt
input was received for the
MC_MoveFeed (Interrupt Feeding)
instruction exceeded the range of
signed 40-bit data when converted to
pulses. Correct the input value for the com-
mand position in the program. The
target value after the interrupt input is
received must not exceed the valid
range for the number of pulses when
it is converted to pulses. Write the program correctly. The input
value for the command position must
not cause the target value after the
interrupt input is received to exceed
the valid range. The valid range is
signed 40-bit data for the number of
pulses when the target value is con-
verted to pulses.
