SINUMERIK 840D sl/840D/840Di/810D Diagnostics Guide (DA), 08/2005 Edition
Definitions: Value specified by the NC via a G command must be in the range 0 to 7.
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
Reactions: - 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. Check parameterization (G
command in the NC).
Program Con-
tinuation:
Clear alarm with the RESET key in all channels. Restart part program.
300764 Axis %1 drive %2 emergency retraction mode/generator mode not possible
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: Emergency retraction/Generator operation is only possible with an active DC link mea-
surement (MD 1161: $MD_FIXED_LINK_VOLTAGE (DC link fixed voltage = 0). In an old
hardware version, no DC link measurement is possible and therefore the error message
300765 might appear in addition if MD 1161: $MD_FIXED_LINK_VOLTAGE (DC link
fixed voltage) is set to 0 in an old hardware version.
Reactions: - 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: Enter the value 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 Con-
tinuation:
Clear alarm with the RESET key in all channels. Restart part program.
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).
Reactions: - 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.
