Remedy: Please inform the authorized personnel/service department.
• Operation without encoder: Reduce the number of encoder lines in MD 1005:
$MD_ENC_RESOL_MOTOR (encoder resolution for motor measuring system), since this
has an impact on the internal number format.
• Optional/additional measure: see operation with encoder
• Operation with encoder: Reduce speed controller cycle MD 1001:
$MD_SPEEDCTRL_CYCLE_TIME (speed controller cycle).
Program Con-
tinuation:
Clear alarm with the RESET key in all channels. Restart part program.
300788 Axis %1 drive %2 parameterization error in current control adaption
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The upper current limit in MD 1181: $MD_CURRCTRL_ADAPT_CURRENT_2 (upper
adaption current limit) is less than the lower current limit in MD 1180:
$MD_CURRCTRL_ADAPT_CURRENT_1 (lower adaption current limit).
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: Modify MD 1181: $MD_CURRCTRL_ADAPT_CURRENT_2 (upper adaption current limit)
and MD 1180: $MD_CURRCTRL_ADAPT_CURRENT_1 (lower adaption current limit).
Program Con-
tinuation:
Clear alarm with the RESET key in all channels. Restart part program.
300789 Axis %1 drive %2 function not supported on this 611D controller module
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: A function was selected that is not possible with this closed-loop control module.
This alarm appears, if:
• a non-available acceleration sensor was activated in MD 1560.
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: Switch off the non-selectable function or use another closed-loop control module!
Program Con-
tinuation:
Clear alarm with the RESET key in all channels. Restart part program.
300790 Axis %1, drive %2 Changeover speed/velocity too small
Parameters: %1 = NC axis number
%2 = Drive number
