Reaction of Controller
Adjustment
The device switches off, restarts after
approx. 60 s.
Final switch-off after three successive at-
tempts (resp. < 60 s).
Check motor and motor connection
cable.
Reset by disconnecting the line voltage.
The device switches off and switches
back on when the temperature drops.
Check cooling of the device (IGBT tem-
perature Diagnostics menu).
The device switches off, restarts after
approx. 60 s.
Final switch-off after three successive at-
tempts (resp. < 60 s).
Check motor and motor connection
cable.
Reset by disconnecting the line voltage.
The device switches off and switches
back on when the temperature drops.
Check cooling of the device (sine filter
Diagnostics menu).
The device switches off, restart after ap-
prox. 30 s. Final switch-off after 5 suc-
cessive attempts (resp. < 10 min), then
reset necessary.
Check high output current.
Immediate switch-off, the error is dis-
played after 75 s.
When voltage okay again, restart after 15
s.
Check line voltage.
Error is displayed after 75 s.
When voltage okay again, restart after 15
s.
Check line voltage.
Error is displayed after 75 s.
When voltage okay again, restart after 15
s.
Check line voltage.
Error is displayed after 75 s.
When voltage okay again, restart after 15
s.
Check line voltage.
The device switches off, restart after ap-
prox. 30 s. Final switch-off after 10 suc-
cessive attempts (resp. < 90 s), then
reset necessary.
Check high output current.
The device switches off and switches
back on when the temperature drops.
Check cooling of the device (filter choke
temperature Diagnostics menu).
The device continues working un-
changed.
check contacts.
