齿轮保护DCS 400没有齿轮保护。然而，使用替代参数可能达到
如果激活了替代参数集，且Alt Speed KP（5.22）和Alt速度TI（5.23）被设置为适当的值。
n对流量优化的评论自整定电机加速至50%标称值时速度应用程序必须允许这样做。如果没有，不要自我调谐。n通量自适应失败检查参数诊断（7.03）并阅读章节
6.4.7诊断信息n更改宏
•更改宏时，所有参数均设置为宏这也将改变。
•如果最初设置的参数取决于已单独切换，不会更改。
•如果SDCS-CON-3A将被交换，我们建议将所有参数设置为出厂设置，以确保以前应用中的所有值将被消除。再生模式加磁场削弱
如果DCS 400拟用于再生模式包括磁场削弱。我们建议
按以下顺序打开驱动器：•仅在零速度下打开命令。
•随时切换运行命令
原因：如果给定了ON和RUN，则使用降低磁场，可能发生磁场电流
由于时间原因，不能足够快地减少磁场绕组的常数，导致电枢过电压和保险丝熔断。
n使用具有标称电枢的电机电流小于4 A
DCS 400的电枢电流范围为：20 A…1000 A。可能的参数设置为：电枢电流小于4 A…1000 A的电机
由于电枢自动调谐功能，通常不支持4A以上。为了确保电枢自动调谐在最小电流为20%时正常工作
需要标称转换器电流。万一最小DCS401.0020最小电流为20A＝4A。
这就是无法设置参数的原因臂电流标称值（1.01）小于4 A。
用于使用额定电枢电流的电机lessthan 4A需要设置参数Arm Cur最大值（3.04）小于100%！
e、 g.电机电枢额定电流=2.4 A设定臂电流标称值（1.01）=4 A
设定臂电流最大值（3.04）=60%
臂电流最大值（3.04）与臂电流标称值（1.01）相关
意味着最大电枢电流为电机的60%标称电流。这种情况下的最大电流为2.4A用于正常操作。
但电枢自动调谐始终与臂电流一起工作
标称值（1.01）。这意味着电机将调整为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!
