Overheat Alarm Level on page 123 for details on drive overheat detection.
Setting 2F: Maintenance Period
The output closes when the cooling fan, capacitor for the control power supply, or DC bus pre-charge relay may require
maintenance as determined by the estimated performance life span of those components. Components performance life is
displayed as a percentage on the HOA keypad screen.
Setting 37: During Frequency Output

Setting 3D: During Speed Search
The output terminal closes while Speed Search is being performed. Refer to b3: Speed Search on page 23 for details.
Setting 3E: PID Feedback Low
The 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 36 for details.
Setting 3F: PID Feedback High
The 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 36 for details.
Setting 4C: During Fast Stop
The output terminal closes when a Fast Stop is being executed. Refer to Settings 15 and 17: Fast Stop (N.O., N.C.) on page
