再生模式下的軟網絡
再生模式下的軟網絡是直流技術的一個具體問題。如果電機的電動勢更大比（電源電壓*1,35*0866），然后保險絲和晶閘管可能被破壞。
盡可能保護驅動器免受損壞
見以下建議：?直流現場保險絲
電樞電路中的半導體保險絲必須：為直流電壓確定尺寸，以確保在以下情況下，有足夠的火花熄滅間隙：錯誤。電源中使用的兩個串聯保險絲提供了折衷方案。
?直流斷路器
半導體熔斷器僅在“硬”網絡中構成對半導體的最佳保護；在“軟網絡”和電機電路中，這種保護值得懷疑。在“軟”網絡中，在再生運行期間，風險增加必須預期傳導通過。
在電機電路，高速直流斷路器這構成了最佳保護。
?凈欠壓的參數調整將參數凈欠壓跳閘（1.10）設置在范圍內0…5%。這使驅動器對.net敏感欠壓，并盡早關閉驅動器可能的可避免保險絲熔斷和損壞晶閘管，但可能由于以下原因導致驅動器關閉：F9電源電壓過低故障經常發生。然后設置參數凈故障時間（1.11）不同于0.0秒至激活自動重合閘功能。
電樞電壓參數調整降低參數臂電壓標稱值（1.02）以便與主電源保持更大的安全距離。
則DCS 400使用自動磁場削弱以達到全速，但在現場會失去扭矩弱化范圍。只是一個建議，可能是解決方案也取決于應用。
?訂購電樞電壓較低的直流電機
如果項目期間已知“軟網絡”調度，然后計算一個直流電機的電樞電壓標稱值。這可能是一種預防措施，使EMF和“軟網絡”之間的安全距離提前。顯示狀態、報警和故障信號

Soft network in regenerative mode Soft network in regenerative mode is a specific problem of DC technology. If EMF of the motor is greater than (Mains Voltage * 1,35 * 0,866) then fuses and thyristors can be destroyed. To protect the drive against damage as far as possible see following recommendations: ? Fuses at DC site Semiconductor fuses in the armature circuit must be dimensioned for DC voltages, so as to assure an adequate spark-quenching gap in the event of a fault. A compromise is provided by two seriesconnected fuses, as used in the power supply. ? DC circuit breaker Semiconductor fuses constitute an optimum protection for the semiconductors only in “hard” networks; in “soft networks, and in the motor circuit, the protection is questionable. In “soft” networks, during regenerative operation, an increased risk of conduction-through must be anticipated. In the motor circuit, high-speed DC circuit-breaker constitutes optimum protection. ? Parameter adjustment for Net Undervoltage Set parameter Net Underv Trip (1.10) in a range of 0…5%. That makes the drive sensitive for net undervoltage and switches off the drive as early as possible. Could avoid blown fuses and damaged thyristors but may be the drive will switch off due to fault F9-Mains Undervoltage very often. Then set parameter Net Fail Time (1.11) different to 0.0 s to activate the auto reclosing function. ? Parameter adjustment for armature voltage Decrease value of parameter Arm Volt Nom (1.02) to have more safety distance to the mains supply. Then DCS 400 is using automatic field weakening to achieve full speed but will lose torque in field weakening range. Is a suggestion only may be also a solution depend on application. ? Order a DC motor with lower armature voltage If ?soft network“ is already known during project scheduling then calculate a DC motor with lower armature voltage nominal. That could be a preventive measure to have more safety distance between EMF and ?soft network“ in advance.
