Setting 1A: During Reverse
A digital output set for “During reverse” closes when the drive is running the motor in the reverse direction.
Status
Description
Open
Motor is being driven in the forward direction or stopped.
Closed
Motor is being driven in reverse.

Setting 1B: During Baseblock (N.C.)
The output opens to indicate that the drive is in a baseblock state. While Baseblock is executed, output transistors do not
operate and no main circuit voltage is output.
Status
Description
Open
Baseblock is being executed.
Closed
Drive is not in a baseblock state.
Setting 1E: Restart Enabled
An output set for “Restart enabled” closes when the drive attempts to restart after a fault has occurred.
The fault restart 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 restart. If the drive cannot successfully restart within the number of attempts permitted
by L5-01, a fault will be triggered and the terminal set to 1E will open.
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)
The output closes when the drive heatsink temperature reaches the level specified by parameter L8-02. .
Setting 22: Mechanical Weakening Detection
The output closes when a mechanical weakening situation is detected.
