Figure 1 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 = 65, 66, 7A, 7B] at terminal S6.
Note:
-
Set the drive to activate 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.
-
When you set L2-29 = 2 [Kinetic Energy Backup Method = System KEB Ride-Thru 1], install a dynamic braking option.
