LI_bFilterOverloadWarnung
BOOL
Status signal "Filter overload"
TRUE Monitoring for filter overload protection has responded:
• Temperature > 155 °C and C00583 ≠ "no response"
- or -
• temperature > C00121 and C00584 ≠ "no response"
- or -
• open circuit sensor and C00594 ≠ "no response"
LI_bMainsVoltageOK
BOOL
Status signal "Voltage supply at L1, L2, and L3 OK"
TRUE The required voltage is available at all three mains voltage inputs L1,
L2, and L3.
LI_bOperational
BOOL
Status signal "Regenerative power supply module is ready for regenerative
feedback"
From software version V2.x onwards, the following applies:
TRUE The regenerative power supply module is ready for regenerative
feedback.
• The device is enabled, i.e. no fault or trouble has occurred (pulse
inhibit is not set).
FALSE The regenerative power supply module is not ready for regenerative
feedback because pulse inhibit is set in the device.
For software version V1.x, the following applies:
This signal is not connected with the state of the device state machine and can
therefore be used for automatic error acknowledgement.
TRUE The regenerative power supply module is ready for regenerative
feedback.
The following conditions are met simultaneously:
• Mains voltage is applied.
• Charging of DC bus is completed.
• There is no short circuit or earth fault.
• There is no device overload, i.e. the device utilisation ( C00064 ) is
below the warning threshold set in C00123 .
TRUEFALSE The regenerative power supply module is not ready for regenerative
feedback anymore because one of the conditions listed under "TRUE"
is no longer met.
Conditions for returning to the "ready for regenerative feedback"
state:
• If a mains failure has been detected, the mains voltage has to be
applied for at least two complete periods after mains recovery,
before the LI_bOperational signal is reset to TRUE.
• If a short circuit or earth fault has occurred, the device is ready for
operation again after approx. 2 s, i.e. after this time the
LI_bOperational signal is automatically reset to TRUE.
• The device utilisation evaluation has a hysteresis of 5 %. This
means that the device utilisation ( C00064 ) must drop to
< ( C00123 - 5 %) before the LI_bOperational signal is reset to
TRUE.
LI_bLimitationActive
BOOL
Status signal "Limitation active"
TRUE A limitation is active.
LI_bRegenActive
BOOL
Status signal "Regenerative feedback active"
TRUE Regenerative feedback operation is active.
LI_bChopperIsActive
BOOL
Status signal "Brake chopper active"
TRUE The brake chopper is active.
