Setting for Communication error detection [C606] to [C609]
[C606: Emb Eth. Communication error detection delay]
Adjustment range: 0.0 - 100.0 sec.
The waiting time of network error detection can be adjusted. If network error was removed during [C606],
inverter will continue normal operation.
[C607: Emb Eth. Communication error operation]
Adjustment range:
0: Turn off bit 10, 14 and 15 of FA36
1: Continue running
2: Deceleration stop
3: Coast stop
4: Network error stop (E-43 trip)
5: Preset speed operation (by C608 setting)
When the communication error is detected, inverter will operate in accordance with the setting of [C607].z
[C608: Emb Eth. Preset speed at communication error]
Adjustment range:
0: None
1 to 15: Preset speed
When the communication error is detected, operation frequency can be selected from preset speed (Only
when [C607] is set to 5). When you set "0: None", inverter will operate in accordance with enabled
frequency command.
[C609: Emb Eth. Communication error detection]
Adjustment range:
0: Always
1: Communication command
2: 1 + during run
Condition of communication error detection can be selected by setting of [C609].
When [C609] is set to "1: Communication command", inverter will enable the communication error
detection if frequency command and communication command 1 from Embedded Ethernet are enabled.
When [C609] is set to "2: 1 + during run", inverter detect the communication error during operation only in
the above condition.
[C666: Emb Eth. I/O scan timeout detection time]
Adjustment range:
0: Disable
0.1-30.0 s
When you use the I/O scanning service of ModbusTCP, inverter will detect the time out error if I/O
scanning is not performed between periods of [C666] setting.
When [C666] is set to "0: Disable", timeout for I/O scanning function does not detected.
