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
Description
Open
Baseblock is being executed.
Closed
Drive is not in a baseblock state.
Setting 1C: Motor 2 Selection
Indicates which motor is selected when another output terminal is set to switch drive operation between two motors (H1-
oo
Refer to Setting 16: Motor 2 Selection on page 282
for details on switching motors.
Status
Description
Open
Motor 1 is selected.
Closed
Motor 2 is selected.
Setting 1D: During Regeneration
Terminal closes when the motor is driven in the regenerative mode.
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.
Refer to L5: Fault Restart on page 322
for details on
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 309
.
Setting 20: Drive Overheat Pre-Alarm (oH)
Overheat Alarm Level on page 328
for details on drive overheat detection.
Setting 22: Mechanical Weakening Detection
The output closes when a mechanical weakening situation is detected.
Refer to Mechanical Weakening Detection on page
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.
Refer to Periodic Maintenance on page 421
for details.
Setting 30: During Torque Limit
The output closes when the motor is operating at the torque limit specified by the L7-
oo
parameters or an analog input. This
setting can only be used in OLV, CLV, AOLV/PM and CLV/PM control modes.
Refer to L7-01 to L7-04: Torque Limits on
for details.
