Error Cause Diagnosis and Remedy Reaction
A0504, SED2
overtemperature
• The warning level of the
SED2 heat sink
temperature (r0037) is
exceeded.
This results in a reduced pulse
frequency and/or a reduced
output frequency (dependent on
parameter setting in (P0610).
Check the following:
• The ambient temperature
must lie within the limits
specified.
• The load conditions and duty
cycle must lie within the
specified conditions.
• The fan must turn when the
SED2 is running.
--
A0505, SED2 I2T
• Warning level
exceeded. The current
supply is reduced if
parameter P0610 is set
to 1.
Check that the duty cycle lies within
the limits specified.
Motor power (P0307) (SED2 power)
(P0206).
--
A0506, SED2
duty cycle
• Difference between the
heat sink temperature
and the IGBT exceeds
the warning levels.
Check the following: Make sure that
the load duty cycles (temporary
overload) lie within the limits
specified.
--
A5011, Motor
overtemperature
I2T
• The motor is
overloaded.
• The duty cycle is
outside the tolerance.
--
A0520, Rectifier
overtemperature
• The warning level of the
rectifier heat sink
temperature is
exceeded.
Check the following:
• The ambient temperature
must lie within the limits
specified.
• The load conditions and duty
cycle must lie within the
specified conditions.
• The fan must turn when the
SED2 is running.
--
A0523, SED2
output fault
• The On-phase is
interrupted at the SED2
output.
--
A0541, Motor
data identification
enabled
• Motor data identification
(P1910) selected or
running.
--
A0600, RTOS
data loss
