Setting 42, 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 selection is selected. If the input is closed,
reverse direction is selected.
Note: This function cannot be used simultaneously with settings 40 and 41.
Setting 44, 45, 46: Offset Frequency 1, 2, 3
These inputs add offset frequencies d7-01, d7-02, and d7-03 to the frequency reference. Refer to d7-01 to d7-03: Offset
Frequency 1 to 3 on page 183 for details.
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. Refer to b2: DC Injection Braking and Short Circuit
Braking on page 133 for details on setting up the DC Injection Braking function.

Setting 61, 62: External Speed Search Command 1, 2
These input functions enable Speed Search even if parameter b3-01 = 0 (no Speed Search at start). See Refer to Speed Search
Activation on page 138 for details on how to use the input signals. Refer to b3: Speed Search on page 135 for more about
Speed Search.
Note: Simultaneously assigning Speed Search 1 and Speed Search 2 to the input terminals will trigger an oPE03 error.
Setting 63: Field Weakening
Enabled in V/f Control. When this input is closed, Field Weakening is performed. For details, see d6: Field Weakening and
Field Forcing.
Setting 65, 66: KEB Ride-Thru 1 (N.C.), 2 (N.O.)
Enables the KEB Ride-Thru function selected in parameter L2-29. Refer to KEB Ride-Thru Function on page 243 for more
information on this function.

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-485/422 port together. The drive transmits data and then confirms that the communications are
received normally. Refer to Self-Diagnostics on page 494 for details on how to use this function.
