5.7 H: Terminal Functions
YASKAWA ELECTRIC SIEP C710616 27G YASKAWA AC Drive A1000 Technical Manual 255
Setting 3C: LOCAL/REMOTE status
Output terminal closes while the drive is set for LOCAL and opens when in REMOTE.
Setting 3D: During Speed Search
Output terminal closes while Speed Search is being performed. Refer to b3: Speed Search on page 160 for details.
Setting 3E: PID feedback low
Output terminal closes when a PID feedback loss (FbL) is detected. The feedback is considered to be lost if it falls below
the level set to b5-13 for longer than the time set to b5-14. Refer to PID Feedback Loss Detection on page 173 for
details.
Setting 3F: PID feedback high
Output terminal closes when a PID feedback loss (FbH) is detected. The feedback is considered to be lost if it rises
beyond the level set to b5-36 for longer than the time set to b5-37. Refer to PID Feedback Loss Detection on page 173
for details.
Setting 4A: During KEB operation
Output terminal closes while KEB is being performed. Refer to KEB Ride-Thru Function on page 275 for a KEB
function description.
Setting 4B: During Short Circuit Braking
Output terminal closes while Short Circuit Braking is being executed.
Setting 4C: During Fast Stop
Output terminal closes when a Fast Stop is being executed. Setting 15, 17: Fast Stop (N.O., N.C.) on page 239.
Setting 4D: oH pre-alarm time limit
Output terminal closes when the drive is reducing the speed due to a drive overheat alarm (L8-03 = 4) and the overheat
alarm has not disappeared after ten frequency reduction operation cycles. Refer to L8-03: Overheat Pre-Alarm
Operation Selection on page 296 for a more detailed description.
Setting 4E: Braking transistor fault (rr)
Output closes if the drive’s internal braking transistor reaches the overheat level.
Setting 4F: Braking resistor overheat (rH)
The braking resistor may overheat due to motor regeneration or too short of a deceleration time setting. The output
terminal closes when the braking resistor exceeds the overheat level.
Setting 60: Internal cooling fan alarm
Output closes when the drive’s internal cooling fan has failed.
Setting 61: Rotor position detection complete
After the Run command is given, the output terminal signals that the drive has detected the rotor position (PM motors).
Setting 62: Memobus Regs1 (It selects it with H2-07 and H2-08.)
The contact output is closed if any of the bits that are specified by H2-08 for the MEMOBUS/Modbus register address
that is set in H2-07 turns on.
Setting 63: Memobus Regs2 (It selects it with H2-09 and H2-10.)
The contact output is closed if any of the bits that are specified by H2-10 for the MEMOBUS/Modbus register address
that is set in H2-09 turns on.
Setting 90 to 92: DriveWorksEZ digital output 1 to 3
These settings are for output functions used in DriveWorksEZ. Normally there is no need to change these settings.
Status Description
Open REMOTE: The external reference that has been selected (either b1-01 and b1-02 or b1-15 and b1-16) is used as frequency reference and Run command source
Closed LOCAL: The digital operator is used as frequency reference and Run command source
