Life-diagnosis

The following parameters provide some information about the use of the inverter.
This includes the following information:
Operating and power-on time of the inverter/control unit
•
Operating time of the internal fan
•
Number of switching cycles of the mains voltage
•
Number of switching cycles of the relay
•
Number of short-circuits and earth faults that have occurred
•
Display of the number of "Imax: Clamp responded too often" errors that have occurred.
•

Display of the rated current of the axis.
Info
Display of the current heatsink temperature.
Warning threshold for temperature monitoring.
• If the heatsink temperature exceeds the threshold set here, the inver-
ter outputs a warning.
• The warning is reset with a hysteresis of approx. 5 °C.
• If the heatsink temperature increases further and exceeds the non-
adjustable error threshold (100 °C), the inverter changes to the
"Fault" device status. The inverter is disabled and thus any further
operation is stopped.
Info
Display showing for how long the inverter has been running so far "Oper-
ation enabled" device state).
Display showing for how long the inverter has been supplied with mains
voltage so far.
Display showing for how long the control unit has been supplied with
voltage so far. This includes the external 24-V supply and voltage supply
via USB module.
• This also includes the time within which the control unit has only
been supplied with an external 24 V voltage.
Display of the number of switching cycles of the mains voltage.
Display of the number of switching cycles of the relay.
Display of the number of short circuits that have occurred.
Display of the number of earth faults that have occurred.
