300765 Axis %1 drive %2 measurement of DC link voltage not possible
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: If the fixed voltage MD 1161: $MD_FIXED_LINK_VOLTAGE(DC link fixed voltage) = 0, no DC link
measurement is possible because the hardware version is wrong.
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not
ready).
Reaction: NC 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.
Remedy: Please inform the authorized personnel/service department. Enter a value greater than zero in the
machine data MD 1161: $MD_FIXED_LINK_VOLTAGE (DC link fixed voltage), or order a new
hardware version of the control module.
Program Clear alarm with the RESET key in all channels. Restart part program.
Continuation:
300766 Axis %1 drive %2 blocking frequency > Shannon frequency
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The blocking frequency of a speed setpoint filter is greater than the Shannon sampling frequency from
the sampling theorem.
Reaction: NC 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.
Remedy: Please inform the authorized personnel/service department.
Current setpoint filter:
The value in MD 1210, 1213,1216 or 1219 must be smaller than the inverse value of two current
controller cycles MD 1000: $MD_CURRENTCTRL_CYCLE_TIME (current controller cycle) (1/2*MD
1000 *31.25 microsec).
Speciality with SINUMERIK 810D:
Current setpoint filters 2,3 and 4 are calculated in the speed controller cycle. This means that MD
1213, 1216 or 1219 must be smaller than the inverse value of two speed controller cycles MD 1001:
$MD_SPEEDCTRL_CYCLE_TIME (speed controller cycle) (1/2*MD 1001 *31.25 microsec).
Program Clear alarm with the RESET key in all channels. Restart part program.
