Overview of Alarms
SIMODRIVE alarms
300774 Axis %1 drive %2 asynchronous mode: changeover speed invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: In mixed operation MSD/AM (MD 1465 > 0) only closed-loop controlled AM mode is allowed (MD1466
<= MD1465).
- Modify MD 1465: $MD_SWITCH_SPEED_MSD_AM (switchover speed MSD/AM)
- Modify MD 1466: $MD_SWITCH_SPD_OPEN_LOOP_AM (switchover speed closed-loop/open-
loop control AM)
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.
Rectify error by selecting pure AM mode (MD1465 = 0) or by deselecting the AM-controlled mode
(MD1466 < MD1465).
- Modify MD 1465: $MD_SWITCH_SPEED_MSD_AM (switchover speed MSD/AM)
- Modify MD 1466: $MD_SWITCH_SPD_OPEN_LOOP_AM (switchover speed closed-loop/open-
loop control AM)
Program Clear alarm with the RESET key in all channels. Restart part program.
Continuation:
300775 Axis %1 drive %2 fixed link voltage of axes differ
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: An unequal fixed voltage MD1161: $MD_FIXED_LINK_VOLTAGE (DC link fixed voltage) has been
found for axes of a drive module. Since a fixed voltage <> 0 replaces the measured DC link voltage
value, but the DC link voltage value is measured only once for all axes of a drive module, the fixed
voltage must be identical on all module axes before it is accepted.
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. Set the same fixed voltage (MD 1161) on
all module axes. $MD_FIXED_LINK_VOLTAGE (DC link fixed voltage) has been found for axes of a
drive module.
Program Clear alarm with the RESET key in all channels. Restart part program.
