Setting 1B: During Baseblock (N.C.)
Output opens to indicate that the drive is in a baseblock state. While Baseblock is executed, output transistors are not switched
and no voltage is output.
Status
Description
Open
Baseblock is being executed.
Closed
Drive is not in a baseblock state.
Setting 1C: Motor 2 Selected
This output function shows the motor 1/2 selection status.
Refer to Setting 16: Motor 2 Selection on page 189
switching motors.
Status
Description
Open
Motor 1 is selected.
Closed
Motor 2 is selected.
Setting 1E: Restart Enabled
The Restart Enabled output will be closed once the fault restart function becomes active and will remain closed until a successful
restart is accomplished or the number of Auto Restart attempts as specified by L5-01 is reached.
for details on automatic fault restart.
Setting 1F: Motor Overload Alarm oL1
An output programmed for this function will be closed 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 213
Setting 20: Drive Overheat Pre-alarm (oH)
Output closes whenever the drive heatsink temperature reaches the level specified by parameter L8-02.
Overheat Alarm Level on page 235
for details on drive overheat detection.
Setting 22: Mechanical Weakening Detection
Output closes when mechanical weakening is detected.
Refer to Mechanical Weakening Detection on page 233
for details.
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.
Setting 30: During Torque Limit
Output closes when the motor is operating at the torque limit specified by the L7-
oo
parameters or an analog input. This
setting is only valid when using Open Loop Vector Control (A1-02 = 2).
Refer to L7-01/02/03/04: Torque Limits on page
for details.
Setting 37: During Frequency Output
Output closes when the drive is outputting a frequency.
Status
Description
Open
Drive is not outputting a frequency. One of the following functions is being performed: Stop, baseblock, DC injection braking (during
initial excitation), short circuit braking.
Closed
Drive is outputting frequency.
