B.2.16.61 Diagnostic Information
DIAGNOSTIC INFORMATION PARAMETERS :
• Digital Input Status → Shows the state of the digital inputs. This is a single byte where bit 0 (LSB)
corresponds to the hardware enable digital input, bit 1 corresponds to digital input 1,…….., bit 7 corresponds
to digital input 7.
• Card ID → It shows the ID value of the power stage.
• Drive Status → Shows the state of selected drive status bits.
o Bit 7 (MSB) = enable state.
o Bit 3 = short circuit (top) fault.
o Bit 2 = short circuit (bottom) fault.
o Bit 1 = regeneration fault.
o Bit 0 (LSB) = PWM dead time generation fault
B.2.16.62 Clear Faults
The Clear Faults panel allows the user to attempt to clear all the faults.
It is possible to clear all faults except for those faults that occur during the initialisation process and faults due to
microprocessor exceptions.
It is possible to determine whether one of these non-clearable faults has occurred by reading the type 1 fault bit in
the status_controller parameter (‘General Status’ byte).
