Setting the automatic restart function
Functionality
After a power failure (F3 "Undervoltage"), the automatic restart function (enabled using
P1210) automatically switches on the motor if an ON command is active. Any faults are
automatically acknowledged by the inverter.
When it comes to power failures (line supply failure), then a differentiation is made between
the following conditions:
●
"Line undervoltage (mains brownout)" is a situation where the line supply is interrupted
and returns before the built-in BOP display has gone dark (this is an extremely short line
supply interruption where the DC link hasn't completely collapsed).
●
"Line failure (mains blackout)" is a situation where the built-in BOP display has gone dark
(this represents a longer line supply interruption where the DC link has completely
collapsed) before the line supply returns.
