Siemens SINAMICS G115D

Note
No thermal motor model for permanent magnet synchronous motor
Protect the permanent magnet synchronous motor against overtemperature by evaluating a
temperature sensor of the motor in the converter.
Parameters
Parameter Description Setting
r0034 CO: Thermal motor load [%] Display and connector output for the motor utiliza‐
tion from motor temperature model 1 (I
2
t).
r0068[0…1] CO: Absolute actual current value
[A]
Displays actual absolute current.
[0] Unsmoothed
[1] Smoothed with p0045
p0344[0...n] Motor weight (for thermal motor
model) [kg]
Sets the motor weight.
Factory setting: 0kg
After selecting an asyn‐
chronous motor
(p0300) or a listed asyn‐
chronous motor
(p0301) during the com‐
missioning, the convert‐
er sets the parameters
to values appropriate for
the motor.
The parameters are
write-protected for lis‐
ted motors (p0301 ≥ 0).
p0604[0...n] Mot_temp_mod 2/KTY alarm
threshold [°C]
Sets the alarm threshold
for monitoring the mo‐
tor temperature of mo‐
tor temperature model
2 or KTY/Pt1000.
Factory setting: 130
p0605[0...n] Mot_temp_mod 1/2/sensor thresh‐
old and temperature value [°C]
Sets the threshold and
temperature value to
monitor the motor tem‐
perature.
Factory setting: 145
p0612[0...n] Motor temperature model activa‐
tion
Activates the motor tem‐
perature model.

p0627[0...n] Motor overtemperature, stator
winding [K]
De󹪝nes the rated over‐
temperature of the sta‐
tor winding referred to
the ambient tempera‐
ture.
