12.6 H: Terminal Function Selection
318 YASKAWA SIEPYEULA5001C LA500 Technical Manual
■ 1B: During Baseblock (N.C.)
Setting Value Function Description
1B During Baseblock (N.C.)
The terminal deactivates during baseblock. When the drive is in baseblock, the drive output transistor stops switching and does
not make DC bus voltage.
ON : The drive is not in baseblock.
OFF : During baseblock
■ 1E: Executing Auto-Restart
Setting Value Function Description
1E Executing Auto-Restart
The terminal activates when the Auto Restart function is trying to restart after a fault.
The terminal deactivates when the Auto Restart function automatically resets a fault. The terminal deactivates
when the Auto Restart function detects the fault again because there were too many restart attempts as specified
by L5-01 [Number of Auto Restart Attempts].
Note:
Refer to L5: Fault Restart on page 332 for more information.
■ 1F: Motor Overload Alarm (oL1)
Setting Value Function Description
1F Motor Overload Alarm
(oL1)
The terminal activates when the electronic thermal protection value of the motor overload protective function is a minimum of
90% of the detection level.
Note:
Refer to L1-01: Motor Overload (oL1) Protection on page 327 for more information.
■ 20: Drive Overheat Pre-Alarm (oH)
Setting Value Function Description
20 Drive Overheat Pre-Alarm
(oH)
The terminal activates when the drive heatsink temperature is at the level set with L8-02 [Overheat Alarm Level].
Note:
Refer to L8-02: Overheat Alarm Level on page 339 for more information.
■ 21: Safe Torque OFF
Setting Value Function Description
21 Safe Torque OFF
The terminal activates (safety stop state) when the safety circuit and safety diagnosis circuit are operating correctly and when
terminals H1-HC and H2-HC are OFF (Open).
Note:
EDM = External Device Monitor
ON : Safety stop state
Terminals H1-HC and H2-HC are OFF (Open) (safety stop state).
OFF : Safety circuit fault or RUN/READY
Terminal H1-HC or terminal H2-HC is OFF (Open) (safety circuit fault), or the two terminals are ON or have
short circuited (RUN/READY).
■ 2F: Maintenance Notification
Setting Value Function Description
2F Maintenance Notification
The terminal activates when drive components are at their estimated maintenance period.
Tells you about the maintenance period for these items:
• IGBT
• Cooling Fan
