Programmable protection functions
External events (parameters
…
)
Five different event signals from the process can be connected to selectable
inputs to generate trips and warnings for the driven equipment. When the
signal is lost, an external event (fault, warning, or a mere log entry) is generated.
Motor phase loss detection (parameter
The parameter selects how the drive reacts whenever a motor phase loss is
detected.
Earth (Ground) fault detection (parameter
Note that
• an earth fault in the supply cable does not activate the protection
• in a grounded supply, the protection activates within 2 milliseconds
• in an ungrounded supply, the supply capacitance must be 1 microfarad or
more
• the capacitive currents caused by shielded motor cables up to 300 meters
will not activate the protection
• the protection is deactivated when the drive is stopped.
