■ 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” 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).
■ 22: Mechanical Weakening Detection
Setting Value Function Description
22 Mechanical Weakening
Detection
The terminal activates when the drive detects mechanical weakening.
Note:
Refer to “Mechanical Weakening Detection Function” for more information.
