Auto-start lock after undervoltage error

​Corrected from:
  • Inverter Drives 8400 StateLine V21.00.00
  • Inverter Drives 8400 HighLine V21.00.00
  • Inverter Drives 8400 TopLine V21.00.00
Response of the new version:
The function restriction has been removed.
 
What happens?
The motor starts after acknowledging an undervoltage error although the auto-start lock function is activated for this error. The motor should only start after an edge change of controller enable.
 
When does this behaviour occur?
Setting "Resp. to DC bus voltage" (C600/1 = 1) "Fault" and "Inhibit at undervoltage"(bit 3) for "Auto-start option" (C142:0). 
 
Which products are affected?
  • Inverter Drives 8400 StateLine
  • Inverter Drives 8400 HighLine
  • Inverter Drives 8400 Topline
Short-term measures:
Implement lock via FB interconnection.
