Omron Q2A Series Technical Manual page 709

The drive detects FbH [Excessive PID Feedback] when the PID feedback value > b5-36 [PID HiHi Limit Level]
for longer than the time set in b5-37 [PID HiHi Time].
Note:
Refer to "PID Feedback Loss Detection" for more information.

V/f CL-V/f OLV CLV AOLV
The terminal activates when the DC bus voltage or control circuit power supply is less than the voltage set with L2-05 [UV
Detection Lvl (Uv1)]. The terminal also turns on when there is a fault with the DC bus voltage.
V/f CL-V/f OLV CLV AOLV
The terminal activates when the drive detects a loss of frequency reference.
763" for more information.
V/f CL-V/f OLV CLV AOLV
The terminal activates when the mounting-type braking resistor is overheating or when there is a braking transistor fault.
V/f CL-V/f OLV CLV AOLV
The terminal activates when the electronic thermal protection value of the motor overload protective function is a minimum of
90% of the detection level.
738" for more information.
V/f CL-V/f OLV CLV AOLV
The terminal activates when the drive heatsink temperature is at the level set with L8-02 [Overheat Alm Level].
774" for more information.
V/f CL-V/f OLV CLV AOLV
The terminal activates when L8-03 = 4 [Overheat Pre-Alarm Selection = Run@L8-19 Rate] and oH [Heatsink Overheat] does
not clear after the drive decreases the frequency for 10 cycles.
774" for more information.
V/f CL-V/f OLV CLV AOLV
The terminal activates when the internal braking transistor overheats and the drive detects an rr [Dynamic Braking Transistor
Fault] fault.
