CORRECTIVE ACTION
No error – unit ready to configure new
properties
Recycle power. If this does not clear

Recycle power. If this does not clear
the fault:
1. Check fan unit, ensure there
are no obstructions preventing
movement.
2. Check cable length to ensure it
is not too long.
If this does not clear fault:
Consult technical service.
Consult technical service
Consult technical service
Check wiring to motor, look for ph -ph
or ph-Earth short circuit. Check drive is
not forced into overload.
Supply problem.
If this occurs during operation, check
power supply voltage.
Drive is too hot.
Drive temperature below operating
range. Raise temperature over -10
degrees C.
Consult technical service
Check communication between drive
and remote sources.
Drive intended for three phase has lost
one leg.
Consult technical service
Parameters lost, reload. If repeated,
