5.7 H: Terminal Functions
YASKAWA ELECTRIC SIEP C710616 30B YASKAWA AC Drive T1000A Technical Manual 199
Parameter Details
5
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 132 for
details.
Setting 3F: PID feedback high
Output terminal closes when an excessive PID feedback (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 132
for details.
Setting 4A: During KEB operation
The output terminal is closed during KEB deceleration, during the reacceleration wait time in S4-12 and when
reaccelerating with the time set in S5-05. The output will open when the previous frequency reference is reached or when
the drive reaccelerates with the acceleration time set in C1. Refer to KEB Function Description on page 252 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 185.
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 50: Disturb Function Up
Output terminal closes if the motor accelerates when the Disturb waveform is being output. For more information, see
S1: Disturb Function on page 250.
Setting 51: Disturb Function Enabled/Disabled
Indicates that the Disturb function is activated by closing whenever the Disturb waveform is output. For more
information, see S1: Disturb Function on page 250.
Setting 52: Uv during KEB
Terminal closes if the DC bus voltage falls below the level set to L2-05 during KEB.
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 100 to 161: Functions 0 to 61 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.
