YASKAWA TOEPYAIGA5001A GA500 DRIVE MAINTENANCE & TROUBLESHOOTING
The terminal activates when you select motor 2.
ON : Motor 2 Selected
OFF : Motor 1 Selected
The terminal activates when the Auto Restart function is trying to restart after a fault.
The terminal activates when the electronic thermal protection value of the motor overload protective function is a minimum of 90%
of the detection level.
The terminal activates when the drive heatsink temperature is at the level set with L8-02 [Overheat Alarm Level].
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).
ON : Safety stop state
OFF : Safety circuit fault or RUN/READY
The terminal activates when the drive detects mechanical weakening.
The terminal activates when drive components are at their estimated maintenance period.
Tells you about the maintenance period for these items:
• IGBT
• Cooling Fan
• Capacitor
• Soft charge bypass relay
The terminal activates when the torque reference is the torque limit set with L7 parameters or H3-02 or H3-10 [MFAI Function
Selection].
The terminal activates when the drive outputs frequency.
ON : The drive is outputting frequency.
OFF : The drive is not outputting frequency.
This terminal activates when the H1-xx = 6A [Drive Enable] terminal activates.
Outputs the pulse that shows the watt hours.
The terminal activates when the Run command source or frequency reference source is LOCAL.
ON : LOCAL
OFF : REMOTE
The terminal activates when the drive is doing speed search.
The terminal activates when the drive detects FbL [PID Feedback Loss].
The terminal activates when the drive detects FbH [Excessive PID Feedback].
The activates during KEB Ride-Thru.
Note:
When A1-02 = 8 [Control Method Selection = EZOLV], this function is available only when you use a PM motor.
The terminal activates when the fast stop is in operation.
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.
fault.
The terminal activates when the braking resistor overheats and the drive detects an rH [Braking Resistor Overheat] fault.
The terminal activates when drive receives a Run command and the drive detects the motor magnetic pole position of the PM motor.
The terminal activates when the bit specified by H2-08 [Modbus Register 1 Bit Select] for the MEMOBUS register address set with
H2-07 [Modbus Register 1 Address Select] activates.
The terminal activates when the bit specified by H2-10 [Modbus Register 2 Bit Select] for the MEMOBUS register address set with
H2-09 [Modbus Register 2 Address Select] activates.
The terminal activates if the monitor value set with H2-20 [Comparator 1 Monitor Selection] is in range of the values of H2-21
[Comparator 1 Lower Limit] and H2-22 [Comparator 1 Upper Limit] for the time set in H2-24 [Comparator 1 On-Delay Time].
The terminal activates if the monitor value set with H2-26 [Comparator 2 Monitor Selection] is not in the range of the values of H2-
27 [Comparator 2 Lower Limit] and H2-28 [Comparator 2 Upper Limit] for the time set in H2-30 [Comparator 2 On-Delay Time].
The terminal activates when there is an external 24V power supply between terminals PS-AC.
ON : The external 24V power supply is supplying power.
OFF : The external 24V power supply is not supplying power.
