Possible causes for resolver error identification failure:

• A controller inhibit was set during resolver error identification.
• A time-out occurred while the algorithm was processed.

• This error may occur if more than 60 seconds pass by between the setting of the "Resolver

error identification" device command and the enable of the controller.

• The setpoint speed was too small (|nset| < 500 rpm).
• The setpoint speed was not traversed for at least 1 second.

Note!

Some applications require that the resolver error identification can also be carried out

during operation.

From version V12.00.00

, the resolver error identification can also be started in the

"OperationEnabled" device status (controller enable) using the device command

C00002/25

= "1: on / start". Then there is no device state change, i.e. the device status

remains at "OperationEnabled".
Furthermore, the following applies to the resolver error identification during operation:

• The progress of the identification run can be seen in

C00002/25

.

• During the resolver error identification run, the direction of rotation of the motor is

not important.

• We recommend to traverse at constant setpoint speed (|nset| > 500 rpm) until

resolver error identification has finished.

• If the application offers only limited space for traversing, reversing is also possible

during active resolver error identification. In this case, ensure that the controller is not

inhibited and that the speed profile is traversed for at least 1 second at constant

setpoint speed (|nset| > 500 rpm).

• The identification is completed if the "0: Off / ready" message is displayed in

C00002/25

.
