Deadtime
Phase B
caused by transistors on
both sides being open at
the same time. This error
indicates that the effective
deadtime is detected
below the manufacturer-
defined threshold.

Over-voltage /
Under-voltage /
Over-
temperature
The drive temperature
which was measured close
to the power MOSFETs
and the DC bus voltage
are checked by the same
hardware protection
circuit against
manufacturer-defined
thresholds. This error
indicates that one or more
of the three errors is/are
triggered.
Please refer to the remedy for over-voltage,
under-voltage and over-temperature.
PhOc Protection
Hardware
Overcurrent
Indicate that the phase
current or the DC bus
current measured is
exceeding the
manufacturer-defined
threshold (referring to the
hardware document, link),
which triggers the
hardware protection
circuit.
Please refer to the remedy for over-current.
Safety Faults
SfeDiIvd Safety Digital
Input Invalid
Invalid digital input signals
received by the safety
input, for example one
signal of the dual-channel
input is read at a different
interval than the other
signal.
The signals must have the
same state within 100 ms.
The cause of the fault usually directs to
misuse of the I/Os or faults in signal tansfer.
Please refer to the documentation about
safety functions of your hardware first, to
check the use of the safety I/Os and of the
safety functions. Check the measured inputs
in 0x2611 Safety digital input diagnostics and
locate the signal leading to the fault. Check
and fix the wiring accordingly with assistance
of tools for example with multimeter
measurement.
