SINUMERIK 840D/SIMODRIVE 611 digital, HLA Module (FBHLA) - 10.03 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.
Under certain circumstances it can be switched over across the entire channel
via MD.
Channel not ready.
NC stopped in response to alarm.
NC start disable.
The NC switches to follow-up mode.
Alarm display.
Interface signals are set.
S The wrong encoder may be in use.
S Does MD 5005: ENC_RESOL_MOTOR (encoder resolution for motor
measuring system) tally with the encoder resolution?
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. Restart
part program.
Axis %1, drive %2 incorrect piston position
%1 = NC axis number
%2 = drive number
Error is triggered when actual position value of drive is negative.
Cause: Position actual value on drive side is counted in the wrong direction.
Incorrect piston zero adjustment.
If the drive is referenced and the offset between the piston zero (piston stop at
A end) and machine zero positions has been entered for MD 5040, then the
piston position in MD 5741 must only display positive values (from zero to maxi-
mum piston stroke).
Mode group not ready.
Under certain circumstances it can be switched over across the entire channel
via MD.
Channel not ready.
NC stopped in response to alarm.
NC start disable.
The NC switches to follow-up mode.
Alarm display.
Interface signals are set.
Correct counting direction of actual position value at drive end if:
1. Pos. setpoint voltage (e.g. function generator) ³Cylinder piston moves from
A to B
If not: Invert control signal (change MD 5476 bit 0)
2. Cylinder piston moves from A to B ³v_act (MD 5707) > 0
If not: Invert actual value (change MD 5011 bit 0)
3. Check piston zero position 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. Restart
part program.
