SINUMERIK 840D/SIMODRIVE 611 digital Descr. of Functions HLA Module (FBHLA) – 04.00 Edition
Switchover for entire channel via MD might be possible.
NC not ready.
Mode group not ready.
NC Stop in response to alarm.
NC Start disable.
The NC switches to follow-up mode.
Alarm is displayed.
Interface signals are set.
The newly calculated data must be saved (softkey: SAVE).
The new parameter settings become operative when the system is next booted!
Switch control system OFF and ON again.
Axis %1, drive %2 signal number var. signalling function invalid
%1 = NC axis number
%2 = drive number
The signal number for output of the appropriate signalling function is illegal. The
permissible signal number range starts at 0 and ends at 29.
Alarm display.
Interface signals are set.
Enter the correct signal number.
Alarm display disappears with alarm cause. No further operator action required.
Axis %1, drive %2 meas. circuit error abs. track, code %3
%1 = NC axis number
%2 = drive number
%3 = error fine coding
Absolute encoder (EQN 1325)
Monitoring of encoder hardware and EnDat interface.
Exact diagnosis via error code MD5023: ENC_ABS_DIAGNOSIS_MOTOR
(diagnosis of absolute track in motor meas. circuit):
Bit No. Meaning
Bit 0 Lighting failure
Bit 1 Signal amplitude too low
Bit 2 Code connection faulty
Bit 3 Overvoltage
Bit 4 Undervoltage
Bit 5 Overcurrent
Bit 6 Battery must be replaced
Bit 7 CRC error (evaluate bit 13 as well)
Bit 8 Encoder cannot be used
Illegal assignment between
absolute and incremental tracks
Bit 9 C/D track on ERN1387 encoder
faulty or EQN encoder connected
