Table of Contents. Plc and drives integration using modbus rtu 48 pages. All Rights Reserved. Page 5: Safety Instructions Safety instructions What this chapter contains This chapter contains safety instructions you must follow when installing, operating and servicing the drive.The application is really simple, used as soft starter and run at constant speed of rpm on centrifugal. So the required parameters configured on basic set-up, motor data etc.
As per ABB manual the fault relates to speed and motor related parameters and that parameters looks alright. I also tried run drive after ID run, it shows ampere but not rpm and motor doesn't run. Any advise what could possibly wrong?

Hi first you should give more information on the type of electrical motor and drive ACS used - size, power in kW and even better if with a photo of the motor plate.
After doing this test, you can do other checks before going to vector mode BR Flavio. Comments 3 New comment by ashesh. Flavio Mussolin Rank: 4 Answered 5 days ago.
Other questions needing answers.ACS Multidrives Catalog. A multidrive is made up of several different units. These sections are called multidrive units.
The most important units are:. Inverters have built-in capacitors for smoothing the voltage of the DC busbars.
The electrical connection to the common DC busbar is fuse protected. However, an optional fuse switch with a capacitor charging device can be selected to disconnect the whole drive unit. A separate pulse encoder interface module is also possible. Other optional features include the prevention of unexpected start-up for the inverters to provide a safe interlock for the system. A diode supply unit is used in non-regenerative drive systems to convert three-phase AC voltage to DC voltage.
A pulse bridge configuration can be implemented with the unit supplied by a three-winding transformer with a thirty degree phase shift between secondary windings. In power control it gives the same firm but gentle performance as DTC gives in motor control. The main circuit consists of a main switch, a filter and a converter.
The converter is hardware compatible with drive units. The converter can operate in both motoring and generating modes. The DC voltage constant and the line current sinusoidal. The control also provides a near unity power factor.
The control performance is excellent due to the ultra-fast control technology, the same as in DTC. A fully regenerative IGBT supply unit with power factor 1 requires no power compensation. The unit can also boost DC voltage e. A thyristor supply unit is used in regnerative drive systems to convert three-phase AC voltage to DC voltage. The thyristor supply unit contains two 6-pulse thyristor bridges in antiparallel connection.
It has the ability to regenerate back to the mains, providing considerable energy savings with applications having excessive braking powers. A pulse bridge configuration can be implemented with two thyristor supply units supplied by a three-winding transformer.
This configuration reduceds harmonics in the supply network. It is possible to connect two supply units in parallel to teh same DC bus to get higher power or redundancy. These two units will be located at the rear ends of the drive DC bus. Higher power is needed, for example, in high power applications where it gives more drive flexibility to connect drive units to the same DC bus, or for high overload requirements. In resistor braking whenever the voltage in the intermediate circuit of a frequency converter exceeds a certain limit, a braking chopper connects the circuit to a braking resistor.
Standard braking resistors are separately available in their own cabinets. Non-standard resistors can be used providing that the specified resistance value is not decreased and that the heat dissipation capacity of the resistor is sufficient for the drive application.
The control unit is equipped with communication interfaces, power supplies and the front devices necessary for the automation equipment. An additional 10 mm is required for marine supports. One DCU can be used for two drive units. I cont. I max : maximum output current. Available for 10 s at start, otherwise as long as allowed by drive temperature. P N : typical motor power in light-overload use. P hd : typical motor power in heavy-duty use.Add new comment.
The internal connection diagrams are exclusively for the ABB service technicians. Have you tried to contact the ABB service in your area? Yes, they have visited our site but they failed to analyse the root cause of this issue.
So in this case, if the service technician could not solve the issue, you need to consider to substitute the drive, because the repair of the unit it may not be convenient. Please also note that you have to reconstruct the cause of the failure, that is, what it originated from.
But is there any way to check the temp sensor of IGBT module. Probably yes, I think it's possible. Having the correct documentation and the necessary skills, I think it can be done.
ABB ACS800 AC Variable Frequency Drive :: Specifications
But do you really need it? If a fundamental control such as temperature control is compromised, I would not try to bypass this control in your place, perhaps jeopardizing a large production plant. ACS is a product that came out of production, I not know how many years of work has your drive but a thought in the replacement, perhaps it is useful to do it. We No. We are in process of upgrading all AcS drives with but the installed quantity of ACS is more which will take time to get fully upgraded.
So, being an responsible person for maintain the drives I need to know how to identify the faulty temp sensor of an IGBT module. My congratulations for your experience and for the large number of drives you have installed. Obviously, I can not know each other's experiences and I have to make suggestions inspired by general concepts and prudence.
When I write about the necessary experience and the appropriate documentation, I refer to those diagrams of the internal parts of the drives that are not made available to users but only to ABB's assistance centers. You could try, since you have the necessary experience, to replace the entire block of IGBT and the interface of temperature acquisition. Again, without schemes, I understand that it is not easy to do.
Hi, In case you replaced the main boards and think the HW parts are OK, the possible solution could be re-loading of the firmware of the drive. But you need a correct software and firmware files, which usually belongs to authorised ABB Service technicians.
Unfortunately that could not be a reason, if you replaced RMIO board. In case you replace the RMIO it could be "programmed" for smaller power unit, e. That parameter is hidden and should be set in the factory, when you order the spare RMIO board, or changed later during installation, from ABB service Another option is to try disconnect the encoder board - one time it creates a problems to me, but not with that fault message.
Check RMIO's firmware version and for what type code it is programmed. That is a last possible reason for the fault, described in FW manual: "Check motor power against unit power.ABB industrial drives are highly flexible AC drives that can be configured to meet the precise needs of industrial applicaitons, and therefore order-based configuration is an integral part of the offering.
These drives cover a wide range of powers and voltages, including industrial voltages up to V. ABB industrial drives come with a wide range of built in options. A key feature of these drives is programmability, which makes adaptation to different applications easy. ABB industrial drives are designed with current ratings to be used in industrial environments for applications requiring high overloadability.
Built in drive options make the installation work fast and easy. The robust enclosures and cabinets, with a wide range of enclosure classes, as well as power terminals, are designed for harsh environments.
One of the most significant design criteria of ABB industrial drives has been long lifetime. Wearing parts such as fans and capacitors have been selected accordingly. This means - together with extensive protection features - excellent reliability in demanding industrial applications. The single drive configuration contains a rectifier, DC link and an inverter in one single AC drive unit.
The single drives are complete AC drives that can be installed without any additional cabinet or enclosure. The single drives are available as wall-mounted, free-standing and cabinet-built constructions. The standard protection class of the single drives is UL Type 1 and higher protection classes are available as an option.
The multidrive principle is based on a standard DC bus arrangement enabling single power entry and common braking resources for several drives. There are several possibilities on the supply side starting from a simple diode supply unit on the supply unit up to highly sophisticated active IGBT supply units. The multidrive construction simplifies the total installation and provides many advantages such as:. ACS modules include everything that is required for a complete drive, there is always a built-in harmonic filtering choke, for example.
In addition to these a selection of external accessories is also available. All the modules can be mounted side by side. In addition to the modules being designed for cabinet assembly, cabinet assembly documentation is included. The documentation gives examples of different cabinet installations, examples of drawings, and hints on the selection of auxiliary equipment. The flexibility and programmability of the modules makes them very viable for various application needs in different areas of industry.
