Commissioning the motor model
The thermal I2t motor model is activated via p0612.0 = 1, the expansions of the motor model
can additionally be activated via p0612.8 = 1.
Note
When commissioning the motor, thermal motor model 1 (p0612.0
= 1) including expansion
= 1) is automatically activated.
Preconditions for automatic activation:
Use of a permanent magnet synchronous motor
There is no motor sensor
No (other) thermal motor model is activated
The most important parameters for thermal motor model 1 and/or for the expansion of this
model are subsequently explained.
When the expansion is subsequently activated, the corresponding parameters of the
expansion are preassigned with the parameter values before activating the expansion.
Parameters for the following set-
tings
p0605 p5390 Alarm threshold
If the model motor temperature (r0632) exceeds the alarm threshold, alarm A07012
"Drive: Motor temperature model 1/3 overtemperature" is output.
p0615 p5391 Fault threshold
If the model motor temperature (r0632) exceeds the fault threshold, fault F07011
"Drive: Motor overtemperature" is output.
p0605 p0627 + 40 °C Rated temperature (winding)
Defines the rated overtemperature of the stator winding referred to the ambient tem-
