YASKAWA ELECTRIC SIEP C710616 27C YASKAWA AC Drive A1000 Technical Manual 233
Parameter Details
5
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 146 for details.
Setting 3E: PID feedback low
Output terminal closes when a PID feedback loss 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 156 for details.
Setting 3F: PID feedback high
Output terminal closes when a PID feedback loss 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 156 for details.
Setting 4A: During KEB operation
Output terminal closes while KEB is being performed. Refer to KEB Ride-Thru Function on page 249 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 218.
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 269 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 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.
Setting 100 to 192: Functions 0 to 92 with inverse output
These settings have the same function as settings 0 to 92 but with inverse output. Set as 1, where the “1” indicates
inverse output and the last two digits specify the setting number of the function.
Examples:
For inverse output of “8: During baseblock”, set 108.
For inverse output of “4A: During KEB” set 14A.
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
