When the input programmed for 42 is closed, the drive will operate in the selected direction. When the input opens, the
drive will stop. The input programmed for 43 selects the direction. If it is open, forward direction is selected; if it is closed,
reverse direction is selected.
Note:
This function can not be used simultaneously with settings 40 and 41.
Setting 44/45/46: Offset Frequency 1/2/3 Addition
These inputs can be used to 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 142
for details.
Setting 60: DC Injection Braking
When a DC Injection Braking command is input while the drive is stopped, DC Injection Braking operation is activated.
When a Run command or a Jog command is input, DC Injection Braking is released.
Refer to b2: DC Injection
Braking on page 109
for details on setting up the DC braking function.

Setting 61/62: Speed Search 1/2
These input functions can be used to enable Speed Search even if parameter b3-01 = 0 (no Speed Search at start.
Refer
to Activation of Speed Search on page 112
for details on how to use the input signals.
When the Speed Search method is set for Current Detection (b3-24 = 0), and the input terminal set for Speed Search 1
(H1-
= 61) is enabled, Speed Search will begin looking for the motor speed from the maximum output frequency. If
the Speed Search 2 input (H1-
= 62) is enabled, Speed Search starts looking for the motor speed starting at the frequency
reference.
Refer to b3: Speed Search on page 110
for more information about Speed Search.
Note:
Operator error oPE03 will result if both Speed Search 1 and Speed Search 2 are set to the input terminals at the same time.
Setting 65/66: KEB Ride-Thru 1 (N.C.)/2 (N.O.)
A digital input programmed for this function can be used to activate the KEB 1 function and detect power supply return.

Refer to Kinetic Energy Backup (KEB) Function on page 189
for details on how to use these input settings.
Setting 67: Communication Test Mode
The drive has a built-in function for self-diagnosing the 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 the communications
are received normally.
Refer to Self-Diagnostics on page 377
for details on how to use this function.
Setting 68: High Slip Braking
Closing an input programmed for this function triggers High Slip Braking. Once HSB is started, the drive has to completely
stop and the HSB input has to be removed before a restart can be performed.
Refer to n3: High Slip Braking (HSB)/
Overexcitation Deceleration on page 209
for details on High Slip Braking.
Setting 6A: Drive Enable
A digital input configured as a Drive Enable input (H1-
= 6A) will prevent the drive from executing a Run command
until the input is closed. When the Drive Enable input is open, the digital operator will display “dnE” to indicate that the
drive is disabled.
