5.1.6 Set rotor displacement angle
For the control of permanent-magnet synchronous machines, the rotor angle – the angle
between the motor phase U and the field axis of the rotor – must be known.
r For Lenze motors the rotor displacement angle for different feedback systems is
already set correctly in C00058/1...3 .
r The device command "Set rotor displacement angle" serves to specify the rotor
displacement angle for the current motor encoder activated in C00495 for an external
motor (see following instructions).
M
How to set the rotor displacement angle for an external motor:
1. If the controller is enabled, inhibit the controller, e.g. with the device command
"Inhibit controller" ( C00002 = "41").
2. Execute device command "Set rotor displacement angle" with C00002 = "51".
The procedure starts with controller enable, if
• a synchronous machine is selected,
• no other identification is active,
• no error (TRIP) has occurred, and
• no test mode is activated.
If one of the above conditions is not met, the procedure is cancelled and the
corresponding controller command status is indicated under C00003 .
Note:
By means of controller inhibit the started procedure can be aborted any time
without making a change in C00058 .
For detailed information about the procedure, please see the following section
"Sequence".
O
Tip!
For controller enable all sources for controller inhibit must be reset. In
C00158 the
sources for controller inhibit are displayed in a bit-coded manner.
The status of the controller command activated under
C00002 is indicated under
C00003 .
Note!
Not required if a Lenze motor is operated on the controller!
Note!
During the procedure of setting the rotor displacement angle, the machine must
not be braked or blocked.
