2. DC Braking during stopping is used to decrease stopping time and also to hold a

stopped load in position. For high inertial loads, a dynamic braking resistor may

be needed for quick decelerations.

8 - 04 Momentary Power Loss Operation Selection Factory Setting: d 0

Settings d 0 Operation stop after momentary power loss

d 1 Operation continue after momentary power loss

Speed search start with the Master Frequency reference

value

d 2 Operation continue after momentary power loss

Speed search start with the min frequency

8 - 05 Maximálisan megengedhető áramkimaradási idő Factory Setting: d 2.0

Settings d 0.3 to d 5.0Sec Unit: 0.1sec

! During a power loss, if the power loss time is less than the time defined by this

parameter, the AC drive will resume operation. If the Maximum Allowable Power Loss

Time is exceeded, the AC drive output is then turned off.

8 - 06 Base-Block Time for Speed Search Factory Setting: d 0.5

Settings d 0.3 to d 5.0Sec Unit: 0.1Sec

! When a momentary power loss is detected, the AC drive turns off for a specified time

interval determined by Pr.8-06 before resuming operation. This time interval is called

Base-Block. This parameter should be set to a value where the residual output voltage

is nearly zero, before the drive resumes operation.

! This parameter also determines the searching time when performing external Base-Block

and fault reset.

8 - 07 Maximum Speed Search Current Level Factory Setting: d 150

Settings d 30 to d 200％ Unit: 1%
