Settin 1B Durin Basebloc (N C )
The 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.
Settin 1E estart 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.
automatic restart.
Settin 1F Motor O erload Alarm (oL1)
The output closes when the motor overload level estimated by the oL1 fault detection exceeds 90% of the oL1 detection level.
Refer to L1-01: Motor Overload Protection Selection on page
Settin 2 Dri e O er eat Pre Alarm (o )
The output closes when the drive heatsink temperature reaches the level specified by parameter L8-02 or an external device
has triggered an oH2 alarm via mult-function digital input H1-

Settin 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 HOA keypad screen.
Settin 7 Durin Fre uency Output
The output closes when the drive is outputting a frequency.
Status
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.
