5.3.1.4 Plug Locking
Signal
Description
PlugLock_MotorStatus
The motor drive status
PlugLock_SelfDiagnosticStatusOutput0
The self-diagnostic status of the full bridge output 0
PlugLock_SelfDiagnosticStatusOutput1
The self-diagnostic status of the full bridge output 1
Table 5-18 Plug Locking Signals
Functionality
The VC-EVCC provides a full bridge solution to control a DC motor. It controls the movement
and the direction of a connected motor and detects electrical faults by reading the voltage
and current levels of the full bridge. The signals and their CAN representatives are for
debugging purposes.
The automatic plug locking is described in the following chapters.
Self-Diagnostic
The electrical faults of the full bridge outputs are detected during movement and also without
output activation.
The VC-EVCC measures the voltage of the full bridge outputs (PlugLock_VoltageOutput0,
PlugLock_VoltageOutput1) cyclically.
If a movement of the motor is requested the detection of an electrical fault of a full bridge
output depends on the direction.
If an error is detected the signal PlugLock_MotorStatus is set to error value. The type of the
error is stored in the signal PlugLock_SelfDiagnosticStatusOutput0 or the signal
PlugLock_SelfDiagnosticStatusOutput1 respectively.
5.3.1.5 Lock Position Evaluation
Signal
Description
POSFeedback_Voltage
The position feedback voltage value
POSFeedback_SelfDiagnosticStatus
The position feedback self-diagnostic status
Table 5-19 Lock Position Evaluation Signals
Functionality
The VC-EVCC detects the position of the inlet lock via the position feedback pin. This is
done via a resistor coded switch. The measured voltage is stored in the signal
POSFeedback_Voltage.
Self-Diagnostic
If POSFeedback_Voltage is in one of the valid ranges for normal operation
POSFeedback_SelfDiagnosticStatus is set to ok.
If POSFeedback_Voltage is in one of the ranges of an electrical fault its type is stored in the
signal POSFeedback_SelfDiagnosticStatus.
If POSFeedback_SelfDiagnosticStatus has any fault value, POSFeedback_Voltage is set to
error.
