2. Protective Functions
2.5 Causes and corrective actions
E.EHR
• Appears when Ethernet communication is interrupted by physical factors while Pr.1431 Ethernet signal loss
detection function selection = "3" or Pr.1457 Extended setting for Ethernet signal loss detection
function selection = "3".
• The inverter output is shut off if Ethernet communication is broken for the time set in Pr.1432 Ethernet
communication check time interval or longer for all devices with IP addresses in the range specified for
Ethernet command source selection (Pr.1449 to Pr.1454).
• Check that the Pr.1432 setting is not too short.
• When the CC-Link IE Field Network Basic is used, the inverter output is shut off in the following cases: the data
addressed to the own station is not received for the predetermined timeout period or longer, or the status bit of
the cyclic transmission addressed to the own station turns OFF (when the master inverter gives a command to
stop the cyclic transmission). (For the details of the timeout period, status bit of the cyclic transmission, and
command to stop the cyclic transmission, refer to the User's Manual of the master device which supports the
CC-Link IE Field Network Basic.)
• When BACnet/IP is used, the inverter output will be shut off after the time period set in Pr.1432 after power is
supplied to the inverter if an IP address of any other inverter falls within the Ethernet IP address range set for
command source selection. (This protective function is available for the Ethernet model and the safety
communication model.)
• Check for a break in the Ethernet cable.
• Check that the Pr.1432 setting is not too short.
• Check for excessive noise around the inverter.
• When the CC-Link IE Field Network Basic is used, check that the timeout period set in the master is not shorter
than the period during which the inverter does not receive the data addressed to the own station.
• When the CC-Link IE Field Network Basic is used, check that the status bit of the cyclic transmission addressed
to the own station is not OFF.
• When BACnet/IP is used, check that IP addresses of other inverters are not included in the Ethernet IP address
range set for command source selection.
• Check that the Ethernet cable is connected to the Ethernet connector properly and the Ethernet cable is not
damaged.
• Set a larger value in Pr.1432.
• When excessive noise occurs around the inverter, change the communication setting of the master. (The noise
may be reduced by setting a shorter timeout period or increasing the number of retries in the communication
setting of the master.)
• When the CC-Link IE Field Network Basic is used, set a timeout period longer than the period during which the
inverter does not receive the data addressed to the own station. When the CC-Link IE Field Network Basic is
used, turn ON the status bit of the cyclic transmission addressed to the own station.
• When BACnet/IP is used, do not include IP addresses of other inverters in the Ethernet IP address range set
for command source selection.

E.CMB
Appears when the combination of the circuit board and the inverter is not appropriate or when the circuit board
is not connected to the inverter.
Check that the board is connected to the inverter properly.
• Connect the board to the inverter properly.
• Contact your sales representative.
E.PID
The inverter output is shut off if the measured value exceeds the PID upper limit or PID lower limit parameter
setting, or the absolute deviation value exceeds the PID deviation parameter setting during PID control. Set this
function in Pr.131 PID upper limit, Pr.132 PID lower limit, Pr.553 PID deviation limit and Pr.554 PID signal
operation selection. This protective function is not available in the initial status.
• Check the meter for a failure or break.
• Check that the parameter settings are correct.
• Check that the meter has no failure or break.
• Set the parameters correctly.
