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 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 44, 45, 46: Offset Frequency 1, 2, 3
These inputs add offset frequencies d7-01, d7-02, and d7-03 to the frequency reference.
Frequency 1 to 3 on page 250
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.

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).
Activation on page 199 for details on how to use the input signals.
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
Field Forcing.
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 645
