Important settings
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
settings
Explanation
p0612.8 = 0
p0612.8 = 1
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
temperature.
1.333 (fixed
value)
p5350
Boost factor
Defines the boost factor for the copper losses at standstill.
p0612 = 0x1
p0612 = 0x101 Activation
Activates the motor module and/or additionally the expansion.
r0632
r0632
Actual temperature
Indicates the stator winding temperature of the motor temperature model.
r0034
r0034
Motor utilization
Indicates the actual motor utilization level.
Taking into account the ambient temperature
If, for thermal motor model 1, a temperature sensor has not been the parameterized, then
motor module 1 automatically uses an ambient temperature of 20 °C for the calculation. You
can enter one of these ambient temperatures deviating from the standard temperature as
follows:
1.
Activate the setting p0612.12 = 1.
This enables parameter p0613. The factory setting is 20 °C.
2.
If you wish to take into account an ambient temperature, which deviates from the factory
setting, in the motor model, then enter the expected ambient temperature in p0613.
Note
When commissioning the motor, the setting p0612.12 = 1 is automatically activated. When
required, the value in p0613 can be changed.
