C001 1.0 Inverter overtemp
"Inverter overtemperature"
(inverter heat sink)
Warning from output stage module (static)
Reduce ambient temperature <50°C or <40°C (see also
Section 8 Technical data).
Check control cabinet ventilation
C002 2.0 Motor overtemp PTC
"Overtemperature of motor
PTC"
(from thermistor) Warning from motor temperature sensor (triggering
threshold reached)
Reduce motor load
Increase motor speed
Use external motor fan
2.1 Motor overtemp I²t
"Overtemperature of motor from
I²t"
(Only if I
2
t- motor (P535) is
programmed.)
Warning: Motor I 2 t monitoring (Attainment of 1.3x the rated
current for the period specified in (P535))
