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.
Setting 1C: Motor 2 Selected
This output function shows the motor 1/2 selection status.
Refer to Setting 16: Motor 2 Selection on page 164

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 185
details.
Setting 20: Heatsink Overheat Pre-alarm (oH)
Output closes whenever the drive heatsink temperature reaches the level specified by parameter L8-02.
Overheat Alarm Level on page 200
for details on drive overheat detection.
Setting 30: During Torque Limit
Output closes when the motor is operating at the torque limit specified by the L7-
parameters or an analog input.
This setting is only valid when using Open Loop Vector Control (A1-02 = 2).
Refer to L7-01 to L7-04: Torque Limits on
for details.
Setting 37: During Frequency Output
Output closes when the drive is outputting a frequency.
