3.2.3. Network error detection (c100 - c103, c523)
▼Display of trip information

Title Function Setting range Description
c100
Communication error
detection delay time
0.0-100.0 sec
The waiting time from when a network error occurs
can be adjusted. If a network error continues past
the time set in c100, it is recognized as a
communication error and the operation of the
inverter follows the setting of c101.
When normal communication returns during the
setting time, a communication error is not displayed
and operation is continued.
*The case of Modbus

TCP protocol
The time-out detection time provides by c523
parameter.
Disconnection detection time =
c523 (Time out) +
c100 (
Communication error detection delay time)
*The case of EtherNet/IP

protocol
-At I/O scanning and connected communication
Time-out time =
RPI42
Connection Timeout Multiplier
[μs] + c100
(communication error detection delay time) [0.1s]
RPI: Request Packet Interval
-At Unconnected communication
Time-out is not operating.
c101
Inverter operation at the
communications loss action
0-5
The operation of the inverter when the
communication fault occurs can be specified.
c102
Preset speed operation
selection
1-15
The operation frequency of the inverter when the
communication fault occurs can be specified. (Only
when c101 is set to 5)
c103
Communication time-out
condition selection
0-2
Select the communication time-out condition.
c523 Time out
0.0: Disable
0.5 - 60 sec.
The waiting time from the occurrence of the
network error to detection can be adjusted.
* When you are using unconnected communication
of the EtherNet/IP protocol, time-out is not
detected.
