5.7 H: Terminal Functions
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 switch
and no main circuit voltage is output.
Status
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.
automatic restart.
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.
Refer to L1-01: Motor Overload Protection Selection on page
Setting 20: Drive Overheat Pre-Alarm (oH)
Closed: The heatsink temperature exceeds the L8-02 level (while L8-03 = 3 or 4), or an external device has triggered an oH2
alarm via multi-function input H1-oo = B.
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.
Setting 37: During Frequency 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.
