Fixed as of:
- i700 servo inverter V01.05.06.9665
Behaviour of the new version:
Die Schaltschwellen-Hysterese der Motortemperatur-Überwachung beträgt jetzt 5 Kelvin, wie in der Dokumentation angegeben.
Kleine Schwankungen der Motortemperatur in Höhe der Warnschwelle führen jetzt nicht mehr zu gehäuften Einträgen ins Logbuch.
What happens?
The switching threshold hysteresis of the motor temperature monitoring (warning and trouble) is not 5 Kelvin, as specified in the documentation, but only 0.5 Kelvin.
In unfavourable cases, frequent warnings may be entered into the logbook.
When does the problem occur?
The problem occurs if the detected motor temperature varies by more than 0.5 Kelvin around the selected warning threshold (0x2D49:3) of the motor temperature monitoring.
Which products are concerned?
- i700 servo inverters ≤ V01.04.00.9125
Short-term measures/recommendations:
If the above-described reaction occurs in individual cases, it is possible not to use the warning threshold of the i700 (set 0x2D49:3 to maximum value) and to monitor the motor temperature in the controller. The current motor temperature is provided via the object 0x2D49:5.
Assessment:
The above-described problem does not have any direct effects on the drive features.
