KEB Ride-Thru Operation as Long as CPU Has Power, KEB Input Used
Here, L2-01 = 3 and an input terminal is set to issue KEB Ride-Thru (H1-oo = 65, 66, 7A, 7B). After decelerating for the
time set to parameter L2-10, the drive checks the DC bus voltage and the status of the digital input. Deceleration continues if
the DC bus voltage is still below the level set in L2-11 or if the digital input assigned to KEB Ride-Thru is still active. Normal
operation resumes when the DC bus voltage rises above the value of L2-11 and the terminal that initiated KEB Rid-Thru is
released.

KEB operation ends when the motor has
come to a stop, even if the power returns and the digital input terminal that initiated
KEB Ride-Thru is cleared.

KEB Operation Wiring Example
Figure 5.74 shows a wiring example to trigger the KEB Ride-Thru at power loss using an undervoltage relay. When a power
loss occurs, the undervoltage relay triggers KEB Ride-Thru at terminal S6 (H1-06 = 65, 66, 7A, 7B). Note that using System
KEB Ride-Thru requires an additional dynamic braking option.
Note: 1. Do not switch off the Run command during momentary power loss. If the Run command is shut off, the drive will not accelerate back
to speed when the power is restored.
2. A dynamic braking option is required to use System KEB 1 (L2-29 = 2).
