Figure 5.49 Example Wiring Diagram for 2-Wire Sequence
Settings 42 and 43: Run and Direction Command for 2-Wire Sequence 2
Sets the drive for 2-Wire sequence 2.
When an input terminal programmed for 42 closes, the drive will operate in the selected direction. The drive will stop when
the input opens.
The input programmed for 43 selects the direction. If the input is open, forward direction is selected. If the input is closed,
reverse direction is selected.
Note:
This function cannot be used simultaneously with settings 40 and 41.
Setting 47: Node Setup
If the SI-S3 option card is connected, closing this terminal sets a node address for operation on a CANopen network.
Setting 60: DC Injection Braking Command
DC Injection Braking is activated when a DC Injection Braking command is input while the drive is stopped. DC Injection
Braking is released when a Run command or a Jog command is input.
The diagram below illustrates DC Injection Braking:

Settings 61 and 62: External Speed Search Command 1, 2
These input functions enable Speed Search even if parameter b3-01 = 0 (no Speed Search at start).
Note:
Assigning Speed Search 1 and Speed Search 2 to input terminals will trigger an oPE03 error.
Settings 65 and 66: KEB Ride-Thru 1 (N.C.), 2 (N.O.)
Enables the KEB Ride-Thru function selected in parameter L2-29.

Simultaneously assigning KEB Ride-Thru 1 and KEB Ride-Thru 2 to the input terminals will trigger an oPE03 error.
Setting 67: Communication Test Mode
The drive has a built-in function to self-diagnose serial communications operation. The test involves wiring the send and
receive terminals of the RS-422/RS-485 port together. The drive transmits data and then confirms that the communications
are received normally.
