SINUMERIK 840D/SIMODRIVE 611 digital Descr. of Functions HLA Module (FBHLA) – 04.00 Edition
Axis %1, drive %2 encoder limit frequency exceeded
%1 = NC axis number
%2 = drive number
Actual velocity is exceeding encoder limit frequency fg,max = 650 kHz.
Mode group not ready
Switchover for entire channel via MD might be possible.
Channel 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.
S
Incorrect encoder connected?
S
Does setting in MD 5005: ENC_RESOL_MOTOR (no. of encoder marks
motor meas. system) match the encoder bar number?
S
Is the encoder cable connected correctly?
S
Is the shield of the encoder cable bonded over a large area?
S
Replace the encoder.
S
Replace the 611D hydraulics module.
Cancel alarm in all channels of this mode group by pressing RESET key. Re-
start the part program.
Axis %1, drive %2 incorrect piston position
%1 = NC axis number
%2 = drive number
The error is activated in response to a negative actual position of the drive.
Cause: Incorrect counting direction of actual position value at drive end.
Piston zero has been incorrectly adjusted.
If the drive is referenced and the offset between piston zero (piston limit stop at
A end) and machine zero has been entered in MD 5040, then the piston posi-
tion in MD 5741 may display only positive values (between zero and max. pis-
ton stroke).
Mode group not ready
Switchover for entire channel via MD might be possible.
Channel 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.
Correct counting direction of actual position value at drive end if:
1. Pos. setpoint voltage (e.g. function generator) ³ Cylinder piston moves from
A to B
If not: Invert control signal (change MD 5476 bit 0)
2. Cylinder piston moves from A to B ³ v_act (MD 5707) > 0
If not: Invert actual value (change MD 5011 bit 0)
3. Check piston zero adjustment and correct if necessary:
Set MD 5012 bits 14 and 15 to zero, save boot file, perform NCK Reset fol-
lowed by reference point approach and then adjust the piston position.
Cancel alarm in all channels of this mode group by pressing RESET key. Re-
start the part program.
