12.7 H: TERMINALS
606 SIEPCYEUOQ2V01A Q2V Technical Manual
Note:
The drive compares the monitors set with H2-26 as absolute values.
■ 3E: PID Fbk Low
Setting Value Function Description
3E PID Fbk Low
The terminal activates when the drive detects FbL [PID Feedback Loss].
The drive detects FbL [PID Feedback Loss] when the PID feedback value < b5-13 [Fdback Loss Lvl] for longer
than the time set in b5-14 [Fdback Loss Time].
Note:
Refer to “PID Feedback Loss Detection” for more information.
■ 3F: PID Fbk High
Setting Value Function Description
3F PID Fbk High
The terminal activates when the drive detects FbH [Excessive PID Feedback].
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.
■ 4A: DC Bus Undervolt
Setting Value Function Description
4A DC Bus Undervolt
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.
ON : The DC bus voltage is less than the setting value of L2-05.
OFF : The DC bus voltage is more than the setting value of L2-05.
■ 4B: FreqRef Loss
Setting Value Function Description
4B FreqRef Loss
The terminal activates when the drive detects a loss of frequency reference.
Note:
Refer to “L4-05: FrefLoss Det.Selection on page 656” for more information.
■ 4C: BrkRes Fault
Setting Value Function Description
4C BrkRes Fault
The terminal activates when the mounting-type braking resistor is overheating or when there is a braking transistor fault.
■ 4D: Motor OL1
Setting Value Function Description
4D Motor 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 Cool Type for OL1 Calc on page 631” for more information.
■ 4E: Drive PreOH
Setting Value Function Description
4E Drive PreOH
The terminal activates when the drive heatsink temperature is at the level set with L8-02 [Overheat Alm Level].
