Setting 1B: During baseblock (N.C.)
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 up to switch drive operation between two motors
(H 1-DD = 16). Refer to
Setting 16: Motor 2 selection on page 173
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: Reset enabled
An output set for “Reset enabled” closes when the drive attempts to reset after a fault has occurred.
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
L5: Automatic Fault Reset on
page 194
for details on automatic reset.
Setting 1F: M otor overload alarm (oL1)
The output closes when the motor overload level estimated by the oL1 fault detection exceeds 90% o f 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
L8-02:
Overheat Alarm Level on page 198
for details on drive overheat detection.
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 o f those components. Component performance life is displayed as a
percentage on the digital operator screen. Refer to
Periodic Maintenance on page 275
for details.
