Heatsink Temperature Monitoring
Parameter
Name / value range / [default setting]
Info
0x2D84:001
(PAR 117/001)
Heatsink temperature monitoring: Actual value
(Heatsink temp.: Heatsink temp.)
•
Read only: x.x °C
Display of the current heatsink temperature.
0x2D84:002
Heatsink temperature monitoring: Warning threshold
50.0 ... [80.0]* ... 100.0 °C
•
Default setting depending on the size.
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. Further operation of the inverter is disabled by
controller inhibit.
5.3.10
Diagnostics timer
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 "Clamp responds too often" errors that have occurred.
