5.7 H: Terminal Functions
222 YASKAWA ELECTRIC SIEP C710616 27C YASKAWA AC Drive A1000 Technical Manual
Setting 47: Node setup
If the SI-S3 option card is connected, closing this terminal will set a node address for operation on a CANopen network.
Setting 60: DC Injection Braking command
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
and Short Circuit Braking on page 144 for details on setting up the DC Injection Braking function.
The diagram below illustrates how the DC Injection Braking function works.

Setting 61, 62: External Speed Search command 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 Activating of Speed Search on page 149 for details on how to use the input signals. Refer to b3: Speed Search on
page 146 for more 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 63: Field Weakening
Enabled in V/f Control. When closed, Field Weakening is performed. For details, Refer to d6: Field Weakening and
Field Forcing on page 192.
Setting 65, 66: KEB Ride-Thru 1 (N.C.), 2 (N.O.)
Used to enable the KEB Ride-Thru function selected in parameter L2-29. Refer to KEB Ride-Thru Function on
page 249 for more information on this function.
Note: Both KEB Ride-Thru 1 and 2 cannot be assigned to the input terminals at the same time. This will trigger setting error oPE03.
Setting 67: Communication test mode
The drive has a built-in function for self-diagnosing 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 505 for details on how to use this function.
Setting 68: High Slip Braking
Closing an input programmed for this function triggers High Slip Braking (available only in V/f and V/f w/PG control
modes). Once HSB is started, the drive has to come to a complete stop and the HSB command must be removed before a
restart can be performed. Refer to n3: High Slip Braking (HSB) and Overexcitation Braking on page 276.
Setting 6A: Drive enable
A digital input configured as a “Drive enable” (H1- = 6A) will prevent the drive from executing a Run command
until the input is closed. When the input is open, the digital operator will display “dnE” to indicate that the drive is
disabled.
If a Run command is enabled before the terminal set for “Drive enable” closes, then the drive will not run until the Run
command is cycled (i.e., a new Run command is required). If the input is opened while the drive is running, the drive will
stop according to the stop method set to b1-03 (Refer to b1-03: Stopping Method Selection on page 138).
