1.7 H: Terminal Functions
Setting 6A: Drive Enable
A digital input configured as a "Drive enable" (H1-oo = 6A) will prevent the drive from executing a Run command until
the input is closed. When the input is open, the HOA keypad will display "dnE" to indicate that the drive is disabled.
If a Run command is enabled before the terminal set for "Drive enable" closes, then the drive will not run until the Run
command is cycled (i.e., a new Run command is required). If the input is opened while the drive is running, the drive will stop
according to the stop method set to b1-03

Setting 70: Drive Enable2
A digital input configured as a Drive Enable2 input (H1-oo = 70) prevents the drive from executing a Run command until
the Drive Enable2 input is closed. When the Drive Enable2 input is open and a Run command is closed, the digital operator
will display "dnE".
The Run command does not need to be cycled after the Drive Enable2 input is closed. The drive will run when both the Run
and Drive Enable2 inputs are closed. If the Drive Enable2 input is opened while the drive is running, the drive will stop using
the method set by parameter b1-03.
Setting A4: BP Emergency Override
When this input is closed the drive will switch into override. If the drive is running the drive will stop running and the motor
will be switched to line voltage. If the drive is not running and dampers are present, they will be actuated. Upon completion
of damper actuation the motor will be run on line voltage.
Setting A5: BP Drive/Bypass Select
Note:
An oPE27 (BP Program Error) will occur if one of the digital inputs is set to A5 and parameter o1-13 or o1-14 is set to 2 (Drive/Bypass).
