齒輪保護DCS 400沒有齒輪保護。然而，使用替代參數可能達到
如果激活了替代參數集，且Alt Speed KP（5.22）和Alt速度TI（5.23）被設置為適當的值。
n對流量優化的評論自整定電機加速至50%標稱值時速度應用程序必須允許這樣做。如果沒有，不要自我調諧。n通量自適應失敗檢查參數診斷（7.03）并閱讀章節
6.4.7診斷信息n更改宏
?更改宏時，所有參數均設置為宏這也將改變。
?如果最初設置的參數取決于已單獨切換，不會更改。
?如果SDCS-CON-3A將被交換，我們建議將所有參數設置為出廠設置，以確保以前應用中的所有值將被消除。再生模式加磁場削弱
如果DCS 400擬用于再生模式包括磁場削弱。我們建議
按以下順序打開驅動器：?僅在零速度下打開命令。
?隨時切換運行命令
原因：如果給定了ON和RUN，則使用降低磁場，可能發生磁場電流
由于時間原因，不能足夠快地減少磁場繞組的常數，導致電樞過電壓和保險絲熔斷。
n使用具有標稱電樞的電機電流小于4 A
DCS 400的電樞電流范圍為：20 A…1000 A。可能的參數設置為：電樞電流小于4 A…1000 A的電機
由于電樞自動調諧功能，通常不支持4A以上。為了確保電樞自動調諧在最小電流為20%時正常工作
需要標稱轉換器電流。萬一最小DCS401.0020最小電流為20A＝4A。
這就是無法設置參數的原因臂電流標稱值（1.01）小于4 A。
用于使用額定電樞電流的電機lessthan 4A需要設置參數Arm Cur最大值（3.04）小于100%！
e、 g.電機電樞額定電流=2.4 A設定臂電流標稱值（1.01）=4 A
設定臂電流最大值（3.04）=60%
臂電流最大值（3.04）與臂電流標稱值（1.01）相關
意味著最大電樞電流為電機的60%標稱電流。這種情況下的最大電流為2.4A用于正常操作。
但電樞自動調諧始終與臂電流一起工作
標稱值（1.01）。這意味著電機將調整為4A！
Gear protection The DCS 400 has no gear protection. However, using the alternative parameters it is possible to reach a smooth rotation change over, if the alternative parameter set is activated and Alt Speed KP (5.22) and Alt Speed TI (5.23) are set to appropriate values. n Comments to flux optimisation When selftuning motor accelerates to 50% nominal speed. The application must allow this. If not do not selftune. n Flux adaptation failed Check parameter Diagnosis (7.03) and read chapter 6.4.7 Diagnostic Messages n Change macro ? When changing macros all parameters set Macro depend will be changed as well. ? If parameters originally set Macro depend have been switched individually, they will not change. ? In case SDCS-CON-3A will be exchanged, we recommend to set all parameters to Factory Setting to ensure that all values from former applications will be extinguished.Regenerative mode plus fieldweakening If a DCS 400 is intended to be used in regenrative mode including field-weakening we recommend the following sequence to switch the drive on: ? Switch ON command only at zero speed. ? Switch RUN command at any time possible Reason: If ON and RUN are given, to regenerate with reduced field, it may happen, that the field current cannot be reduced fast enough caused by the time constant of the field winding, which results in armature overvoltage and blown fuses. n Using motors with nominal armature current less than 4 A The armature current range for DCS 400 is 20 A…1000 A. Possible parameter setting for that is 4 A…1000 A. Motors with an armature current less than 4A are usually not supported because of armature autotuning function. To make sure that armature autotuning works right a minimum current of 20% of nominal converter current is necessary. In case of smallest DCS401.0020 minimum current is 20% of 20 A = 4 A. That’s the reason why not possible to set parameter Arm Cur Nom (1.01) less than 4 A. For using motors with armature current nominal lessthan 4A it’s necessary to set parameter Arm Cur Max (3.04) less than 100% ! e.g. Motor armature current nominal = 2,4 A Set Arm Cur Nom (1.01) = 4 A Set Arm Cur Max (3.04) = 60% Arm Cur Max (3.04) is related to Arm Cur Nom (1.01) meaning maximum armature current is 60% of motor nominal current. Maximum current in this case is 2,4A for normal operation. But armature autotuning works always with Arm Cur Nom (1.01). That means motor will be tuned with 4A!
