■
3F: PID Feedback High
Setting Value Function
3F PID Feedback High
The drive detects FbH [Excessive PID Feedback] when the PID feedback value > b5-36 [PID High Feedback
Detection Lvl] for longer than the time set in b5-37 [PID High Feedback Detection Time].
Note:
Refer to "PID Feedback Loss Detection" for more information.
■
4A: During KEB Ride-Thru
Setting Value Function
4A During KEB Ride-Thru
Note:
Refer to "KEB Ride-Thru function" for more information.
■
4B: During Short Circuit Braking
Setting Value Function
4B During Short Circuit
Braking
Note:
• When A1-02 = 8 [Control Method Selection = EZOLV], this function is available when you use a PM motor.
• Refer to "b2: DC Injection Braking and Short Circuit Braking" for more information.
■
4C: During Fast Stop
Setting Value Function
4C During Fast Stop
■
4D: oH Pre-Alarm Reduction Limit
Setting Value Function
4D oH Pre-Alarm Time Limit
Note:
Refer to "L8-03: Overheat Pre-Alarm Selection" for more information.
■
4E: Braking Transistor Fault (rr)
Setting Value Function
4E Braking Transistor Fault
(rr)
■
4F: Braking Resistor Overheat (rH)
Setting Value Function
4F Braking Resistor Overheat
(rH)
The braking resistor overheats when the deceleration time is short and there is too much motor regeneration
energy.

V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
The terminal activates when L8-03 = 4 [Overheat Pre-Alarm Selection = Operate at Reduced Speed (L8-19)] and oH [Heatsink
Overheat] does not clear after the drive decreases the frequency for 10 cycles.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
The terminal activates when the internal braking transistor overheats and the drive detects an rr [Dynamic Braking Transistor
Fault] fault.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
The terminal activates when the braking resistor overheats and the drive detects an rH [Braking Resistor Overheat] fault.
