Blocking protection
Description
The "Motor blocked" fault is only triggered when the speed of the drive is below the
adjustable speed threshold in p2175.
● For vector control, then the speed controller must also be at its limit.
● For V/f control, then the current limit must also be reached.
Once the on delay (p2177) has elapsed, the message "Motor blocked" and fault F07900 are
generated.
The blocking monitoring enable can be deactivated via p2144.
