DC bus overvoltage [0x007b000e]
DC bus undervoltage [0x007b000f]
Power control: Task overflow [0x007b0013]
Internal communication error (host MCTRL) [0x007b0014]
Feedback: Open circuit at X9 [0x007b001b]

Response (Lenze setting printed in bold) Setting: C00600 ( Adjustable response)
 None  System fault  Fault  Trouble  Quick stop by trouble  Warning locked  Warning  Information
Cause Remedy
Since the braking energy is too high, the DC-bus voltage
is higher than the overvoltage threshold which results
from the mains setting in C00173 .
• Use brake resistor or regenerative module.
• Check setting under C00173 .

Cause Remedy
DC bus voltage is lower than the undervoltage threshold
resulting from the mains setting under C00173 .
• Check mains voltage.
• Check setting under C00173 .
