n this example, the drive detects that the DC bus voltage is less than the level set in
L2-05
and starts the KEB
operation. When you return power during KEB operation, the drive will continue KEB operation when the KEB
Ride-Thru is input, although the time set in
L2-10 [Minimum KEB Time]
expired. The motor accelerates again
after you cancel the KEB Ride-Thru.
Figure 12.109 KEB Operation through KEB Ride-Thru Input
■
KEB Ride-Thru End Detection
Parameter
L2-01 [RideThru@PwrLoss]
and a digital input programmed for KEB set the KEB function end
detection.
Use the Momentary Power Loss Ride-Thru Time to Cancel KEB Operation
The following figure shows an example with this configuration:
•
L2-01 = 1 [Enabled] and L2-50 = 2 [RidThruMode@PwrLoss = KEB Mode]
is set.
•
KEB Ride-Thru is not used.
The drive starts deceleration through KEB operation. When the time set in
L2-10 [Minimum KEB Time]
expires,
the drive stops the KEB operation and then it accelerates the motor again until it is at the frequency reference
value used before the power loss.
If you do not return the DC bus voltage in the time set in
L2-02 [RideThrough Time@Power Loss]
, the drive
detects
Uv1 [DC Bus Undervoltage]
and the drive turns off its output.
Figure 12.110 Cancel the KEB Operation after the Momentary Power Loss Ride-Thru Time Is Expired without KEB
Ride-Thru
*1
When
L2-07 = 0.00 [KEB Accel Time = 0.00 s]
, the drive accelerates again as specified by the applicable
Acceleration Time [C1-01, C1-03, C1-05, C1-07]
, and usual operation continues.
Use the Momentary Power Loss Ride-Thru Time and KEB Ride-Thru to Cancel KEB Operation
The following figure shows an example with this configuration:
•
L2-01 = 1 [Enabled] and L2-50 = 2 [KEB Mode]
.
•
Use
KEB Ride-Thru 1 [H1-xx = 40, 41]
or
KEB Ride-Thru 2 [H1-xx = 42, 43]
.
