Parameters: %1 = Axis name, spindle number %2 = Encoder number Definitions: For PROFIdrive only: The encoder configured for the spec ified axis could not be found. For example, a PROFIBUS slave was configured on the NC but it is not contained in the SDB or defective hardware was reported for it. Reaction: 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. Remedy: Possible causes: - MD 30240 $MA_ENC_TYPE not equal to 0 as a result of an oversight; the en coder should actually be simulated (= 0). - MD 30220 $MA_ENC_MODULE_NR entered incorrectly, i.e. the logical drive numbers were transposed and an invalid value is stored for this drive in MD 13050 $MN_DRIVE_LOGIC_ADDRESS (see next paragraph), or a drive number which does not exist on the bus was entered (check the number for slaves, for example). - MD 13050 $MN_DRIVE_LOGIC_ADDRESS contains val ues which were not configured on the Profibus (i.e. the values are not in SDB Type 2000) or different addresses were selected for the input and output slots of the drive in the Profibus configuration. - A fatal encoder error was detected during the sele ction of the encoder (encoder defective, removed), so that park status cannot be left (in such a case, this alarm is triggered instead of alarm 25000/25001 - please refer to them for other possible causes of the error). Diagnostics Manual (DAsl), 03/2009 Program Continuation: Switch control OFF - ON.
