Overheat Alarm Level on page 123
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
The output closes when the drive is outputting a frequency.
Status
Open
Drive is stopped or one of the following functions is being performed: baseblock, DC Injection Braking.

digital output set for "Drive enable" will also close.
Setting 39: Power Consumption Pulse Output
Outputs a pulse to indicate the watt hours.
Setting 3A: Regenerated Power Pulse Output
Outputs a pulse to indicate the regenerated power.
Setting 3D: During Speed Search
The output terminal closes while Speed Search is being performed.
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.
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.
