Use
KEB Ride-Thru 1 [H1-xx = 40, 41]
or
KEB Ride-Thru 2 [H1-xx = 42, 43]
.
The drive starts deceleration through KEB operation. When the motor decelerates for the time set in
L2-10
, the
drive measures the DC bus voltage and the status of the digital input set for KEB Ride-Thru. When the DC bus
voltage is less than the level set in
L2-11
, or if the digital input set to KEB Ride-Thru is active, deceleration
continues. When the DC bus voltage is more than the level set in
L2-11
, the drive ends KEB operation. The drive
accelerates the motor to the frequency reference value before the power loss, and usual operation continues. When
the KEB Ride-Thru continues to be input after the time set in
L2-02
is expired, the drive uses the KEB Ride-Thru
function to continue to decelerate. When you cancel the KEB Ride-Thru, the motor accelerates again, and usual
operation continues.
Figure 12.113 Use the KEB Ride-Thru to Cancel KEB Operation when Restoration of Power Occurs while the Control
Power (Power Supply to the Control Board) is Maintained
*1
When
L2-07 = 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.
KEB Operation when L2-01 = 1, and L2-50 = 4 [KEB Decel to Stop]
The drive starts deceleration through KEB operation. If you do not input the Run command, the motor cannot
restart. The drive will continue to decelerate until the motor comes to the minimum output frequency or a
complete stop. If you return power during deceleration, the drive continues to decelerate.
■
KEB Operation Wiring Example
shows an example that uses an undervoltage relay to trigger the KEB Ride-Thru at power loss.
When a power loss occurs, the undervoltage relay triggers
KEB Ride-Thru [H1-06 = 40, 41, 42, 43]
at terminal
DI6.
Note:
•
Configure the drive to turn ON the Run command while the KEB function is operating. If you turn off the Run command, the drive will
not accelerate back to speed when you return power.
•
A dynamic braking option is necessary for
System KEB1 Ride-Thru [L2-29 = 3].
