Figure 5.95 shows a wiring diagram when assigning an input terminal to trigger KEB (H1- = 65 or 66).

Figure 5.95 KEB Terminal Wiring Example
Note: 1. Make sure that the Run command remains enabled during power loss. If the Run command is released, then the drive will not be able
to accelerate back up to the frequency reference once power is restored.
2. A braking resistor option is needed when using the synchronous accel/decel feature offered by KEB 2 (S4-01 = 1) while S5-10 is set
to 0.
n S4-01: KEB Mode Selection
Determines which of the three types of KEB to use.
To have the drive perform KEB itself (i.e., using its own independent deceleration rate), then use KEB 1 or KEB 3 by
setting S4-01 to either 1 or 3.
For drives running on a line system in a textile application, it may be beneficial to synchronize the deceleration rate for
all drives on the line. Use KEB 2 (S4-01 = 2) to have all drive decelerate together.
Setting 0: KEB Disabled
Drive will not use KEB when power loss occurs.
