Axis %1 drive %2 maximum current monitoring |
Parameters: |
%1 = NC axis number %2 = Drive number |
Definitions: |
1. A serious fault occured during actual current measurement. 2. The maximum current threshold was exceeded while the rotor position identification was active (FDD only). |
Reactions: |
- Mode group not ready. - The NC switches to follow-up mode. - Channel not ready. - NC Start disable in this channel. |
Remedy: |
- Interface signals are set. - Alarm display. - NC Stop on alarm. - Channel not ready. Please inform the authorized personnel/service department. Modify MD 1107: $MD_INVERTER_MAX_CURRENT (transistor limit current) Check the motor data (motor code) Check the controller data, current/speed controller gain too high Reduce MD 1145: $MD_STALL_TORQUE_REDUCTION (stall torque reduction factor). Check the power section and motor terminals (including motor protection), possibly power section too small |
Program Continuation: |
Increase MD 1254: $MD_CURRENT_MONITOR_FILTER_TIME (time constant for current monitoring) Error in actual current measurement (if necessary, replace 611D power section or controller module) If rotor position identification is active, check MD 1019 $MD_CURRENT_ROTORPOS_IDENT (current for rotor position identification) and, if necessary, reduce the setting. Switch control OFF - ON. |
