Program Continuation:

Axis %1 drive %2 motor encoder is not adjusted

%1 = NC axis number %2 = Drive number

The stored serial number of the encoder on a linear motor encoder with an EnDat interface does not match the number of the active encoder. It is therefore assumed that the encoder has not been started up with the motor in question before or has not been adapted to the motor.

-    Mode group not ready.

-    The NC switches to follow-up mode.

-    Channel not ready.

-    NC Start disable in this channel.

-    Interface signals are set.

-    Alarm display.

-    NC Stop on alarm.

-    Channel not ready.

For 1FN3 linear motors: Measure the rotor position offset to the EMF of the U_R phase and add it as commutation angle offset to MD 1016 $MD_COMMUTATION_ANGLE_OFFSET. Then set MD 1017

$STARTUP_ASSISTANCE to "-1" to store the serial number of the Endat encoder. Then save the bootfiles and execute an NCK Reset. Otherwise: To determine the commutation angle offset in MD 1016, initiate the rotor position identifier via MD 1017 = 1. After the error has been acknowledged, the identification is carried out.

Clear alarm with the RESET key in all channels of this mode group. Restart part program.
