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.
Setting 2F: Maintenance Period
The output closes when the cooling fan, DC bus capacitors, 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 digital operator screen.
Refer to Performance Life Monitors Used for Component Replacement on page 292.
Setting 37: During Frequency Output
The output closes when the drive is outputting a frequency.
Status Description
Open Drive is stopped or one of the following functions is being performed: baseblock, DC Injection Braking, Short Circuit Braking.
Closed Drive is outputting frequency.

Setting 38: Drive Enable
Reflects the status of a digital input configured as a “Drive enable” input (H1-oo = 6A). If that digital input closes, then the
digital output set for “Drive enable” will also close.
Setting 39: Watt Hour Pulse Output
Outputs a pulse to indicate the watt hours.
Setting 3C: LOCAL/REMOTE Status
The output terminal closes while the drive is set for LOCAL and opens when in REMOTE.
