Parameter Description
p0344 Motor weight (for thermal motor type) (factory setting: 0.0 kg) After selecting an induc‐
tion motor (p0300) or a
listed induction motor
(p0301) during the com‐
missioning, the inverter
sets the parameters to
values appropriate for
the motor.
The parameters are
write-protected for listed
motors (p0301 ≥ 0).
p0604 Mot_temp_mod 2/KTY alarm threshold (factory setting: 130.0°
C)
Motor temperature > p0604 ⇒ fault F07011.
p0605 Mot_temp_mod 1/2 threshold (factory setting: 145.0° C)
Motor temperature > p0605 ⇒ alarm A07012.
p0612 Mot_temp_mod activation
.01 1 signal: Activate motor temperature model 2 for induc‐
tion motors
.09 1 signal: Activate motor temperature model 2 expansions
The inverter sets bit 09 = 1 after commissioning. If you
load the parameter settings for firmware version ≤ V4.6
into the inverter, bit 09 = 0 remains.
p0627 Motor overtemperature, stator winding (factory setting: 80 K)
p0625 Motor ambient temperature during commissioning (factory setting: 20° C)
Specification of the motor ambient temperature in °C at the instant of the motor data iden‐
tification.
r0632 Mot_temp_mod stator winding temperature [°C]
p0640 Current limit [A]
Further information is provided in the function charts 8016 and 8017 of the List Manual.
Thermal motor model 1 for synchronous reluctance motors
Thermal motor model 1 calculates the temperature of the stator winding from the motor current
and the thermal time constant of the motor model.
