YASKAWA L1000A Technical Manual page 195

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
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 211
Setting 2F: Maintenance period
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. Component performance life is displayed as a
percentage on the digital operator screen. Refer to
Setting 30: During torque limit
Output closes when the motor is operating at the torque limit specified by the L7-
setting can only be used in OLV, CLV and CLV/PM control modes. Refer to
for details.
Setting 33: Within position lock bandwidth
Output closes when the motor rotor position is within the position lock bandwidth (S3-04) during Position Lock at start or
stop.
Setting 37: During frequency output
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.

Setting 50: Brake control
This setting can be used in the brake sequence for the elevator application. Closing the output terminal should cause the
brake to release, and opening the terminal should apply the brake. Refer to
Setting 51: Output contactor control
Assigning this command to an output terminal can send a signal to the controller to close the output contactor. The output
contactor should open when the terminal is released.
