Please inform the authorized personnel/service department.
Rectify the error in the entry for the feedforward control structure MD 1004 or by deselect-
ing the asynchronous mode MD 1465 > MD 1146.
• Modify MD 1004: $MD_CTRL_CONFIG (configuration structure)
• Modify MD 1465: $MD_SWITCH_SPEED_MSD_AM (switchover speed MSD/AM)
• Modify MD 1146: $MD_MOTOR_MAX_ALLOWED_SPEED (maximum motor speed)
Clear alarm with the RESET key in all channels. Restart part program.
Axis %1 drive %2 asynchronous mode: changeover speed invalid
%1 = NC axis number
%2 = Drive number
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).
- 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.
Please inform the authorized personnel/service department.
Rectify error by selecting pure AM mode (MD1465 = 0) or by deselecting the AM-con-
trolled 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)
Clear alarm with the RESET key in all channels. Restart part program.
Axis %1 drive %2 fixed link voltage of axes differ
%1 = NC axis number
%2 = Drive number
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 mea-
sured 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).
- 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.
