Possible cause
Fuse blown.
Power loss on operational current on one
or several phases.
Fault
The main contactor or circuit breaker is
open.
Main contactor opens too quickly at stop.
Excessive disturbances in the operational
supplying network.
Short power loss on all three phases in the
Fault
operational network.
Operational current too low or lost on one
or several phases.
Fault Phase loss on line side or motor side.
Thyristors not able to conduct
The motor is too small.
(current is out of measuring range).
Solution
• Check and replace fuses in all three
phases.
• Check and correct supplying opera-
tional network.
• Check and close contactor/breaker or
any external switching device.
• Control main contactor with Run
signal relay on terminal 4. See chapter
5.2.4.6.
• Add a time relay before contactor
opening.
• If Stop Ramp not is needed, set Stop
Ramp Time to 0.
• Check and correct supplying opera-
tional network.
• Check and correct supplying opera-
tional network.
• Check and correct supplying network
• Check and correct supplying network
• See Phase loss EF14.
• Check and replace PCB/thyristor.
Contact your ABB Sales Office for
replacement kit.
• Check that the softstarter corresponds
to the motor size.
