TECO e510 series - Kinetic Energy Back-Up Deceleration Time (KEB）; Main Circuit Low Voltage Detection; Power Loss Ride Trough Time

4-64
 07-11=0：When auto-restarting the inverter will detect the rotating speed of the motor. The Motor will
be controlled to accelerate from the present speed to the target speed.
 07-11=1：The inverter restart from 0 speed to set frequency in acceleration time when auto-restart.
07-12 Power loss ride trough time
Range
【0.0 ~ 2.0】

Power loss ride through allows continued operation after a momentary power failure as long as the
power has recovered within the set time in parameter 07-12, otherwise Inverter will trip with LVC fault
due to power loss.

On power recovery the inverter will carry out a speed search function after which the inverter output
Frequency is ramped up the running frequency before the power failure.
.Power loss recovery time setting depends on the Inverter rating; the range will be from 1 to 2 secs.

When 07-00 = 0: Power loss ride through is disabled.

When 07-00 = 1: If the power loss time is less than setting in 07-12, the drive will restart with speed
search after 0.5 seconds delay, and there is no limits on the number of restarts.
※
Caution
If there is a long power loss (loss time exceeds the set value of parameter 07-12) while power loss ride
through function is selected by 07-00=1 and also the Run command is set to external switch 00-02=1, to
avoid any danger to persons on power recovery, must ensure that the power and Run switch are in off
position.

※ Note:
1. When 07-14≠0, the momentary power loss and restart is disabled, the inverter will do KEB function.
2. When input power is turned off, CPU detects the DC bus Voltage and as soon as DC bus Voltage
becomes lower than190V (220V system) or 380V (440V system), then the KEB function is activated.
