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).
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: 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 Clear alarm with the RESET key in all channels. Restart part program.
Continuation:
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.
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: Switch off the non-selectable function or use another closed-loop control module!
Program Clear alarm with the RESET key in all channels. Restart part program.
Continuation:
300790 Axis %1, drive %2 Changeover speed/velocity too small
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: With the selected setting of MD1466, the induced voltage is too small in the lower speed range in order
to be able to guarantee safe, sensorless operation. With the specified speed, the induced voltage must
at least reach 40 V (phase-to-phase, effective).
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: The following must be ensured:
Rotary synchronous machine : MD1466 > 40000 / MD1114
Linear machine : MD1466 > 1386 / MD1114
Asynchronous machine : MD1466 >= 150 rpm
Program Clear alarm with the RESET key in all channels. Restart part program.
