5.7 H: Terminal Functions
YASKAWA ELECTRIC SIEP C710616 30B YASKAWA AC Drive T1000A Technical Manual 189
Parameter Details
5
Note: 1. If a Run command is input while DC Injection 2 is active, then DC Injection 1 will be performed for the time set in b2-03.
Acceleration will not start until the time set in b2-03 has passed.
2. If the frequency reference is kept at zero after a Run command has been entered and the time b2-03 has passed, then the drive will
continue to perform DC Injection 2 until the digital input is released.
3. A Run command has priority over the DC Injection 2 command.
4. If b2-01 is set to a smaller value than parameter E1-09 (minimum frequency), then DC Injection Braking will begin as soon as the
frequency falls to the value set to E1-09.
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). See
Refer to Activating of Speed Search on page 123 for details on how to use the input signals. Refer to b3: Speed Search
on page 121 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, see d6: Field Weakening and Field
Forcing on page 162.
Setting 65, 66: KEB (N.C.), (N.O.)
A digital input programmed for this function can be used to activate the KEB 1 function and detect power supply return.
If KEB is activated, the drive uses the method selected in parameter S4-01 to perform KEB.
Note: These inputs have no effect when setting S4-01 = 0.
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 472 for details on how to use this function.
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 113).
