F506 506 M1OverTemp Motor measured overtemperature:
Wait until the motor is cooled down. The motor fan will
continue to work until the motor is cooled down under the
alarm level. It is not possible to reset the fault as long as
the motor remains too hot. Check:
−
M1FaultLimTemp (31.07), M1KlixonSel (31.08)
−
M1AlarmLimTemp (31.06)
−
motor temperature
−
motor fan supply voltage
−
motor fan direction of rotation
−
motor fan components
−
motor cooling air inlet (e.g. filter)
−
motor cooling air outlet
−
motor temperature sensors and cabling

F507 507 M1OverLoad Motor calculated overload:
Wait until the motor is cooled down. The motor fan will
continue to work until the motor is calculated down under
the alarm level. It is not possible to reset the fault as long
as the motor remains too hot. Check:

MainsLowVolt
Mains low (under-) voltage (AC):
Check:
−
PwrLossTrip (30.21), UNetMin1 (30.22), UNetMin2
(30.23), PowrDownTime (30.24)
−
if all 3 phases are present:
−
measure the fuses F100 to F102 on the SDCS-PIN-F)
−
if the mains voltage is within the set tolerance
−
if the main contactor closes and opens
−
if the mains voltage scaling is correct [NomMainsVolt
(99.10)]
−
connector X12 and X13 on SDCS-CON-F
−
connector X12 and X13 on SDCS-PIN-F
−
check if the field circuit has no short circuit or ground
fault
−
In case the On command [UsedMCW (7.04) bit 0] is
