14. Er.990: Power input phase loss
Cause:
•
The three-phase servo drive of 1 kW below is allowed to run under single-phase power but
the fault and alarm of power input phase loss (H0A-00) is enabled.
Cause Conrming Method Corrective Action
When H0A-00 = 1 (allow
faults and warnings at
power input phase loss
protection), the three-
phase servo drive (0.75
kW) (H01-02 = 5) can
run under single-phase
power. In this case, the
drive reports the alarm.
•
Check whether it is the three-
phase servo drive that is
allowed to run under single-
phase power.
•
If the alarm is still reported when
the three-phase servo drive is
connected to three-phase power,
troubleshoot the alarm as Er.420
(power cable phase loss).
•
If the alarm is still reported when
the three-phase servo drive is
connected to the single-phase
power, set H0A-00 to 0.
15. Er.994: CAN address conict
Cause Conrming Method Corrective Action
CANlink address conict
occurs.
•
Check whether H0C-00 (servo
shaft address) is allocated
repeatedly.
Allocate the servo shaft address
of the salves and ensure that the
allocation of H0C-00 is not repeated.
6.2.4 Internal Faults
