4.2.3

Ident

The controller has been provided with functions for automatically detecting the motor parameters,

the resolver error and the pole position of a synchronous motor. If such an "identification" is active,

the controller is in the "Ident" status.
The "Ident" device status can only be reached from the "

SwitchedOn

" device status, i.e. the

controller must be inhibited first so that identification can be started afterwards via the

corresponding device command:

After the identification is completed, the status changes back to "

SwitchedOn

".

Stop!

During the identification of the motor parameters or the pole position, the controller

does not respond to setpoint changes or control processes (e.g. speed setpoints, quick

stop, torque limitations).
While an identification is being executed,

• the application remains active,
• all system interfaces (IO, bus systems, etc.) remain active,
• error monitoring remains active,
• the inverter is controlled independently of the setpoint sources.
