40 — 69 Indicates an MD29 fault
If the Drive trips, the index display shows triP, and the data message will
flash. The data display shows a mnemonic to indicate the reason for the
trip.
The last four trip codes are stored in parameters 10.25 through to 10.28,
and are available for interrogation unaffected by power down/up cycles.
The data stored in these parameters is updated only by the next trip
event.
NOTE
In the event of any trip, all RO parameter values are frozen and
remain so for interrogation while the cause of the fault is
investigated. To enter parameter adjustment mode from the trip
mode, press any of the five adjustment keys. To re-enter trip mode,
go to Menu 00 and press LEFT key.
NOTE
If the trip persists, contact your supplier. Attempts to repair the
Drive may invalidate the warranty.
Mentor ll User Guide
Issue Number: 12
An instantaneous protection trip has been activated due to excess current in the armature circuit
Drive has detected that the firing angle has advanced but no current feedback has been detected
Indicates that an error has been detected in the parameter set read from the EEprom at power-up
Overcurrent trip at the 24V supply output terminal (TB4-33) has operated, indicating an overload
in the external circuit connected to this supply. Maximum current available is 200mA
Parameter 10.34 = 1. The external trip set up by the user has operated
No signal from tachogenerator (tachometer) or encoder (pulse tachometer)
The polarity of the feedback tacho or encoder polarity is incorrect. This trip does not operate on
1Q Drives
No current in field supply circuit
The user has initiated self-tuning (05.09) and field current has been detected
Excess current detected in field current feedback. If current feedback is present and firing angle
is phased back, then trip
A hardware fault has been detected during the self-diagnosis routine performed after power-up.
Users are recommended to consult the supplier of the Drive
The integrating overload protection has reached trip level
Thyristor (SCR) heatsink overtemperature. Only on Drives equipped with heatsink thermistors
(thermal switches)
Indicates a fault in the MDA1 hardware has been detected by malfunctioning of Processor 1
software
Indicates a Processor 2 malfunction, or a software bug (MD29 option)
Connections to E1 and E3 are not the same phases as are connected to L1 and L3. Investigate
and correct
One or more of the internal power supplies is out of tolerance
(Only in serial comms mode 3) No input data detected
One or more of the power (input) supply phases is open-circuit
Motor protection thermistor (thermal switch) has initiated a trip indicating windings overheating.
Trip threshold 3kΩ±5%. Reset 1.8kΩ

Нужны принципиальные схемы,может кусками,или сервисную инфу к электроприводу
Mentor II M420R и блоку возбуждения FXM 5.
Руководства пользователя на эти устройства есть.Хотелось бы схемотехники.
Возможно дурит блок возбуждения,хотелось бы подготовится.
Спасибо!

Ну обычно в общем доступе таких схем нет, обычный метод научного тыка, но может вам повезет.

В мануале на FXM5 (на английском) на вскидку поболее информации в сравнении с русской версией.
Буду изучать,сравнивать.Спасибо!

NikolayCH,
Можно попросить выложить руководство на данный привод.
Так же имею похожий привод и вскоре собираюсь приладить к месту.
Ранее краем глаза глянул, вроде бы ничего сложного не узрел все доходчиво прописано на самой колодке подключения
И все же почитать не мешает

sibhdd документы по приводу на рабочем компе.
Попробую выложить чуть позже.

NikolayCH, Да очень вас прошу !!!
В плане то что подключу по данным с колодки сомнений у меня нет.
Просто привод настроен на 3Ф 380 В, а я хотел запитать его от 3Ф 220 В
для этого нужно перепаять перемычку! На плате есть указатель на варианты запитки и все же перепутать никак нельзя. Надо почитать. Опять таки нужна инфа по интерфейсу настройки.

sibhdd по поводу подключения к 3 х 220 v. на вскидку — даже и не знаю.
Какую нагрузку хотите им крутить?
Вроде мозги его должны от 220 завестись.Руководство ещё не выучил,но
по поводу перемычки ,если LK 1- вроде,как для калибровки тахометра.
Других пока не заметил.Возможно придется подбирать резисторы обратной
связи по току.

Mentor-2 Drive Zero Speed Problem Hello Experts, Q.2) in other application when drive stop and start again motor not rotating & drive shows negative speed indication- here when we rotate conveyor once manually (spanner etc) motor start rotating normally (this also we are unable to understand- give some idea on same also.) thanks in advance. |

From where is your zero-speed signal coming? Ideally, it should come from a zero-speed switch on the tail pully shaft of the conveyor (opposite end of the conveyor from the driven end). If your zero-speed signal is not indicating 0 speed when the motor is standing still, then there is a problem with that signal. It may be generated by something other than the proper zero-speed switch. It sounds like someone has used a signal from the Mentor DC Drive in place of a true zero-speed switch. That may indicate the condition of the drive, but it will never be able to tell if the conveyor belt breaks or comes off the pully. |

I am not familar with your model, but it sounds like the Zero Speed output is being «calculated» by the drive electronics. If you want to know positively that the conveyor belt is not moving, you need to add a Zero Speed Switch that looks at the shaft rotation of the conveyor. |

You cannot expect a DC drive using only armature feedback (no tach or encoder) to know with any precision when the shaft is stationary. If you do have a tach or encoder, those should report zero speed correctly. |

In a previous life I used Mentors & Mentor II’s a lot — used on extruder drives and conveyors etc. We always used them set to either tacho feedback or encoder feedback although in an emergency, AVF was suitable to get the conveyor or bit of plant running. What Mentor II are you using?. Single quad or 4 quad?. What means of speed feedback are you using?. You need to sit down with a Mentor II drive manual and go through the settings — menu 1 is speed reference and menu 3 is all about feedback selection and speed loops. You need to look at these to see if they are set up for your drive and how you want your drive to control it’s speed. (assuming all the other vital parameters are ok eg current limits, ramps etc). If you need total accuracy then you will need an encoder or tacho. Bolty.
