Fault Reset Command Active (Setting: 11)
If a multifunction output is set for this function the output is switched ON as long as a fault reset command is
input at one of the digital inputs.
Reverse Direction (Setting: 1A)
If a multifunction output is programmed for this function the output is switched ON whenever the drive is
turning the motor in the direction that corresponds to reverse direction.
OH Pre-Alarm (Setting: 20)
The overheat fault function (OH) is designed to protect the drive from excessive temperature damage. Ther-
mistors attached to the heatsink of the drive monitor the temperature and will fault the drive if the temperature
reaches 105 °C.
An OH Pre-Alarm digital output will close whenever the heatsink temperature reaches the level specified by
parameter L8-02. Parameter L8-03 will determine the drive's response to reaching the OH Pre-Alarm level
(besides closing the configured digital output).
Drive Enabled (Setting: 38)
If a multifunction output is programmed for this function the output is switched ON when the drive is enabled.
The drive can be enabled or disabled using a digital multifunction input.
During oH and Reduced Frequency (Setting: 3A)
If a multifunction output is programmed for this function the output is switched ON when an inverter overheat
alarm has occurred and the motor is running at reduced speed.
RUN Command from Option Card/Communication Option (Setting: 3B)
If a multifunction output is set to 3B the output will be ON when the RUN command is put in from the built-in
communication (Memobus, N2, PI) OR from a communication option card (SI-P1, SI-N1, etc.). If both RUN
commands are off the output will be open.
Drive Waiting (Setting: 39)
The digital output will close during the timeout period between the input of a RUN command and the expiring
of the delay time specified by b1-11.
