Motor overtemperature, stator winding (factory setting: 80 K)
Mot_temp_mod 1/3 alarm threshold (factory setting: 110.0° C)
Motor temperature > p5390 ⇒ alarm A07012.
Mot_temp_mod 1/3 fault threshold (factory setting: 120.0° C)
Motor temperature > p5391 ⇒ fault F07011.
Mot_temp_mod 1/3 ambient air temperature (factory setting: 20° C)
Expected motor ambient temperature in °C for motor operation.
Motor ambient temperature during commissioning (factory setting: 20° C)
Motor ambient temperature in °C at the instant of the motor data identification.
Mot_temp_mod stator winding temperature [°C]
After commissioning, the
inverter sets
bit 8 = bit 12 = 1. If you load
the parameter settings for
firmware version ≤
V4.7 SP3 into the inverter,
bit 08 = bit 12 = 0 remain.

After selecting a
synchronous re‐
luctance motor
(p0300 = 600) dur‐
ing the commis‐
sioning, the inver‐
ter sets the param‐
eters to values ap‐
propriate for the
motor type.
The parameters
are write-protec‐
ted for listed mo‐
tors (p0301 ≥ 0).
