Diagnostics

Diagnostic messages can be error messages or warning messages and are generated automatically. Existing diagnostic messages are displayed by the LEDs on the front of the controller card. In case of warning messages, the drive remains in regulated operation.

In case of malfunctions, the SBM is withdrawn and an attempt is made automatically to brake the drive to a standstill and to withdraw the controller enable afterwards. If no braking can be carried out successfully, the power output stage enable is withdrawn automatically and the drive runs out.

If an error causes a coasting motor (e. g. EF is withdrawn while RF is active or encoder error) the brake output will be set and a potential motor holding brake engages.

In order to avoid brake wear, the application has to ensure in cases of errors with previous warning that the drive is braked before EF is withdrawn.

 

Diagnostic messages can be read out by AIPEX PRO or the superordinate controller via the fieldbus and are described in the 'PDK_025786_Diagnose' documentation.
