Temperature calculation without sensor
In the vector control mode (P1300 = 20/21/22/23) Temperature calculations is possible
without sensor. The following parameters have to be set.
Parameter
Description (Parameter name and factory setting (if not variable) in bold)
Setting
P0621= 1
Motor temperature identification after restart
0: No identification (default)
1: Temperature identification only at first "motor on" after power cycle
2: Temperature identification at each motor on.
P0622 = …
Motor magnetizing time for temperature identification after stator restistance identification
This parameter will be initialised with a value for one calculating cycle of the motor
temperature. It depends on the identified rotor time constant. Due to accuracy reasons this
calculation may be performed several times.
Selection of command source
The available command sources depend on the used CU.
Default setting on the control unit used the command source is set per default to different
values.
