5.7 H: Terminal Functions
YASKAWA ELECTRIC SIEP C710616 35D YASKAWA AC Drive E1000 Technical Manual 189
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 169.
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 215 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-422/RS-485 port together. The drive transmits data and then confirms that the
communications are received normally. Refer to Self-Diagnostics on page 436 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 control mode). 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 241.
Setting 69: Jog 2
The Jog 2 function applies to 3-Wire control only. If a digital input is configured as Jog 2 (H1- = 69) when the drive
is not in 3-Wire Control, an oPE03 fault will occur. The Jog 2 input will cause the drive to ramp to the Jog Frequency
Reference (d1-17) in the direction dictated by the Fwd/Rev input of the 3-Wire Control mode. Accelerating to and from
the Jog Frequency Reference will be determined by the active Accel/Decel parameters.
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 125).
Setting 7A, 7B: KEB Ride-Thru 2 (N.C., N.O.)
An input terminal set to 7A or 7B can trigger Single Drive KEB Ride-Thru during deceleration. If enabled, L2-29 is
disregarded. Refer to KEB Ride-Thru Function on page 215 for details.
Note: KEB Ride-Thru 1 and 2 cannot both be assigned to the input terminals at the same time. Doing so will trigger an oPE3 error.
Setting 7C, 7D: Short Circuit Braking (N.O., N.C.) (OLV/PM)
An input programmed for this function can be used to activate Short Circuit Braking in Open Loop Vector control modes
for PM motors. By linking all three phases of a PM motor, Short Circuit Braking creates a braking torque that can be used
to stop a rotating motor or prevent a motor from coasting due to external forces (such as the windmill effect in fan
applications). Parameter b2-18 can be used to limit the current during Short Circuit Braking.
