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)
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.
Parameter Description
P0700 = 2/6 Selection of command source
This selects the digital command source
0: Factory default setting
1: BOP (Basic Operator Panel)
2: Terminals (default) (P0701 ... P0709), factory setting for CU240S
4: USS on RS232
5: USS on RS485 (not available with CU240S DP and CU240S DP-F)
6: Fieldbus (default) (P2050 ... P02091), factory setting for CU240S DP and CU240S DP-F,
not available with CU240S)
