SINUMERIK, SIMODRIVE Diagnostics Manual (DA), 11/2006 Edition
300772 Axis %1 drive %2 asynchronous mode: speed control gain too high
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The value in MD 1451: $MD_SPEEDCTRL_GAIN_1_AM (proportional gain of AM speed controller)
is too high.
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. The current set in MD1451:
$MD_SPEEDCTRL_GAIN_1_AM (proportional gain of AM speed controller).
Program
Continuation:
Clear alarm with the RESET key in all channels. Restart part program.
300773 Axis %1 drive %2 asynchronous mode: feedforward control structure not
possible
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: 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).
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 the error in the entry for the feedforward control structure MD 1004 or by deselecting 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)
Program
Continuation:
Clear alarm with the RESET key in all channels. Restart part program.
