The error message is displayed when there is hardware error, software error or lose of
connection of wire.
Display of trip information
■
- 23 (Error code : 55) : Add-on option 1 error
e
(This error is displayed at the time the bottom side option has an error or only one option
is installed and has an error.)
- 24 (Error code : 56) : Add-on option 2 error
e
(This error is displayed at the time the two-units are installed and the upper side option
has an error.)
6.2. Disconnection error of network cable
■Display of trip information
err8 (Error code : 27) : Communication error
■Related parameter
『f850 Disconnection detection extended time』
『f851 Inverter operation at disconnection』
『 f852 Preset sped operation selection』
The range : 0.0 to 100.0 sec.
The waiting time from when a network error occurs to when a communication error
" err8 " is displayed can be adjusted. If a network error continues past the time set
in f850, it is recognized as a communication error and " err8 " is displayed.
When normal communication returns during the set time, a communication error is
not displayed and operation is continued.
The range 0 : Stop and Communication release
(CMOD, FMOD)
: None (continued operation)
1
: Deceleration stop
2
: Coast stop
3
: Network error (err8 trip)
4
: Preset speed operation (by f852 setting)
5
The action of the inverter when the communication error occurred can be specified.
Setting range
0
to 15 : Preset speed operation (by parameter setting)
1
: None
