- NC not ready.
- Channel not ready.
- Channel not ready.
- NC Stop on alarm.
- NC Start disable in this channel.
- The NC switches to follow-up mode.
- Alarm display.
- Interface signals are set.
Please inform the authorized personnel/service department. The current set in MD1019:
$MD_SPEEDCTRL_GAIN_1_AM (proportional gain of AM speed controller).
Clear alarm with the RESET key in all channels. Restart part program.
Axis %1 drive %2 asynchronous mode: feedforward control structure not
possible
%1 = NC axis number
%2 = Drive number
In asynchronous mode (select by MD 1465 < MD 1146) a feedforward control structure
(MD 1004, bit 0 = 1) is not possible.
• Modify MD 1465: $MD_SWITCH_SPEED_MSD_AM (switchover speed MSD/AM)
• Modify MD 1146: $MD_MOTOR_MAX_ALLOWED_SPEED (maximum motor speed)
• Modify MD 1004: $MD_CTRL_CONFIG (configuration structure)
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
- NC not ready.
- Channel not ready.
- Channel not ready.
- NC Stop on alarm.
- NC Start disable in this channel.
- The NC switches to follow-up mode.
- Alarm display.
- Interface signals are set.
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).
