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 = 16). Refer to Setting 16: Motor 2 Selection on page 212 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 257 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 238.
Setting 20: Drive Overheat Pre-Alarm (oH)
The output closes when the drive heatsink temperature reaches the level specified by parameter L8-02. Refer to L8-02:
Overheat Alarm Level on page 263 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
260 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. Components performance life is displayed as a percentage on
the digital operator screen. Refer to Periodic Maintenance on page 351.
Setting 30: During Torque Limit
Note:
PM motor control modes are not available on 600 V class drives, CIMR-Ao5oooooooo.
