It was old and not really man enough for the job, but it worked. Until just over a week ago when it announced it had had enough, and died. The inverter was powered up to 50Hz by closing a switch on a logic input. I replaced it with an Altivar 28 inverter, which is man enough for the job but with far more control options, which I don't need.
All I need is for it to give me 3 ph V at 50Hz. End of! It seems fine, giving the option again of a 2 wire logic input across which I have the same switch as before. The 28 has 50Hz and 2 wire control as factory default settings, and I have set it to 'auto-reset' I think! Can anyone help in pointing me in the right direction here? There seems masses for configuration options which I surely don't need, but there must be one somewhere which I do need.
Inverters especially modern ones should have their outputs connected directly to the motor with no switchgear in-between. I expect that you are getting no output because the inverter is detecting the open circuit on its outputs due to the switches being open. Direction and speed control should all be controlled via the logic and analogue inputs to the inverter.
Firstly, since this is an electronic device, and the old one had been working, presumably fine, why did it choose now to stop?
Electronic devices of this type don't tend to stop working unless there's a good reason, so this may be more important than you might think. Secondly, the chances of the old controlling system working directly with a new inverter, even from the same manufacturer, are not good.
Chances are that the wiring will have to be modified to take account of the differences. Is this a dual-winding motor? If it is, I have to say that they can be a complete nightmare when it comes to inverters. I'm aware of one installation where to get this to work at all without blowing up triacs on switching, zero-speed sensing and some extra logic had to be employed.
The back emf generated in the winding not being used especially when switching from high to low speed can produce enough oomph to destroy even massively oversized and over-rated triacs. Specifications: page References: page Dimensions: page Connections: page Functions: page Drive with heatsink.

InI: Replaces the current configuration with the factory settings. FCS automatically switches to nO as soon as this action has been performed. These parameters can only be modified when the drive controller is stopped and no run command is present. A stop pulse is sufficient to control stopping. Although this renders the RUN button on the drive controller inactive, the potentiometer still provides the speed reference. This causes rrS, tCt, and all functions affecting logic inputs to return to their factory setting.
If both inputs are high on power up, the controller will run forward. If the forward or reverse input is high when the drive trn controller is powered up, the input must be cycled before the drive controller will start the motor. If forward is activated while the controller is running in reverse, the controller will run forward. Display parameters can be accessed with the drive controller running or stopped. Some functions have numerous associated parameters.
To clarify programming and keep parameter lists short, these functions have been grouped together in sub-. Like menus, sub-menus are identified by a dash after their code, for example LIF-. When the drive controller is running, the value of one of the monitoring parameters is displayed. The factory setting is output frequency rFr. To change the parameter displayed, scroll to the desired monitoring parameter and press the ENT key.
To retain your selection as the new default, press and hold the ENT key again for 2 seconds. The value of this parameter will be displayed during operation, even after power to the drive controller has been cycled. If the new choice is not confirmed by pressing the ENT key a second time, the drive controller will return to the previous parameter after power is cycled. LFr Frequency reference for control via integrated terminal or remote terminal.

If a problem occurs during setup or operation, ensure that all ambient environment,. The first fault detected is stored and displayed, flashing, on the screen.
If the drive controller will not start and there is no display indication, check the power supply to the drive controller. Faults which cannot be automatically reset are listed in the table beginning on page To clear these faults: 1.
Remove power from the drive controller. Wait for the display to go off completely. Determine the cause of the fault and correct it. Reapply power. Fault Probable Cause Remedy Restore the factory settings or load the. See Configuration fault suited to the application.

Power Up After a Manual Fault Reset or Stop Command With the factory configuration, when the drive controller is powered up after a manual fault reset or a stop command, the forward and reverse commands must be reset for the drive controller to start.
Removing the Protective Cover When IP20 protection is adequate, remove the protective cover on top of the drive controller as shown below. Communication Monitoring A dash appears after menu codes to differentiate them from parameter codes.
