Setting 1A: During down direction
A digital output set for "During down direction" will close whenever the drive is running the elevator in down direction.
Status
Open Elevator is being driven in up direction or stopped.
Closed Elevator is being driven in down direction.

During Down Direction
Setting 1B: During baseblock (N.C.)
Output opens to indicate that the drive is in a baseblock state. While Baseblock is executed, output transistors do not
switch and no main circuit voltage is output.
Status
Open Baseblock is being executed.
Closed Drive is not in a baseblock state.
Setting 1E: Reset enabled
An output set for "Reset enabled" closes when the drive attempts to reset after a fault has occurred.
The fault reset function allows the drive to automatically clear a fault. The terminal set to 1E will close after the fault is
cleared and the drive has attempted to reset. If the drive cannot successfully reset within the number of attempts
permitted by L5-01, a fault will be triggered and the terminal set to 1E will open. Refer to
page 140 for details on automatic reset.
Setting 1F: Motor overload alarm (oL1)
The output closes when the motor overload level estimated by the oL1 fault detection exceeds 90% of the oL1 detection
level.
Setting 20: Drive overheat pre-alarm (oH)
Output closes whenever the drive heatsink temperature reaches the level specified by parameter L8-02. Refer to
Overheat Alarm Level on page 144
