Parameter Description
p0318 Motor standstill current (factory setting: 0.0 A) 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).
p0611 I2t motor model thermal time constant (factory setting: 0 s)
p0612 Mot_temp_mod activation
.00 1 signal: Activate motor temperature model 1
.08 1 signal: Activate extended mode,
overtemperature at rated load:
p0627
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.
.12 0 signal: Ambient temperature =
p0625
1 signal: Ambient temperature =
p0613
p0627 Motor overtemperature, stator winding (factory setting: 80 K)
p5390 Mot_temp_mod 1/3 alarm threshold (factory setting: 110.0° C)
Motor temperature > p5390 ⇒ alarm A07012.
p5391 Mot_temp_mod 1/3 fault threshold (factory setting: 120.0° C)
Motor temperature > p5391 ⇒ fault F07011.
p0613 Mot_temp_mod 1/3 ambient air temperature (factory setting: 20° C)
Expected motor ambient temperature in °C for motor operation.
p0625 Motor ambient temperature during commissioning (factory setting: 20° C)
Motor ambient temperature in °C at the instant of the motor data identification.
r0632 Mot_temp_mod stator winding temperature [°C]
