DI2 has a higher priority than DI1, i. Start and stop the drive. Stop the drive in according to parameter Stop-Mode and afterwards switch the drive off. Auto Main con- 6. Stop the drive in according to parameter Stop-Mode and afterwards switch the drive off and resets speed reference to zero. Slower has precedence above faster.

COAST is the fastest way to stop the current controller. The dcs40 controller will decrease the armature current to zero as fast as possible.
This command will stop the drive so that the motor is left running and friction together with the load will decrease the speed to zero. The speed feedback with tachogenerator is set with The significance of the inputs are defined by a macro.

The technical data and specifications are valid as of going to press. The thyristor power converter weighs quite a lot and should therefore not be held by the front cover.

When these functions are executed, the unit will procedure for the state concerned is not meticulously complied with be reset after an error and will then resume operation. The conformity procedure is matter of responsibility of ABB Automation Products GmbH and of the machine manufactur- ers or the plant builders corresponding to their share of the ex- tension of the electrical equipment.
Installation Definitions Earth, earthing for safety Ground, grounding for EMC, connection with chassis or housing with low inductance Important instructions for dcs4400 with line fil- ters Filter in an earthed line TN or TT Network The filters are suitable for earthed lines only, for example in public European V lines. Europe for example with V between the phases. Such lines have an earthed neutral conduc- tor. ABB offers suitable three – phase filters for V and 25 A Installation Separation A separation transformer makes line chokes unnecessary because transformers of its leakage inductance, and a grounded screen between its windings saves an EMC filter, see and 4.
The screen and the iron core must be well connected with the mounting plate of the con- verter. Installation Screening Signal cables The cables for digital signals, which are longer than 3 m and all ca- bles for analogue signals, must be screened.
Each screen must be connected at both ends by metal clamps see figure 5. Installation Power cables If a screen is not necessary see 13 the armature current cable without screens must be a four-wire cable because two wires are needed as con- ductors for the parasitic RF currents from the motor to the RF filter in the cubicle. Installation Others Earthed public The rated voltages of a public European low voltage line are V low voltage between the 3 phases and V between a phase and the neutral lines conductor.
These voltages are provided by a transformer with its 3- phase secondary winding in star connection. Installation Industrial low Industrial low voltage lines dfs400 local lines in dcs00 or factories.
The loads tolerate higher noise levels. Therefore and because industrial lines xcs400 decoupled from public lines by their transformers and distances, converters do not need EMC filters at industrial low-voltage lines see 6. Installation Connection exam- See figure 5.
Installation Important hint The example shows the principle structure of a DC drive and its connections. It is not ds400 binding recommendation, and it cannot re- spect all conditions of a plant. Therefore each drive must be con- sidered separately and with respect to the special application. Addi- tionally avb general installation and safety rules must be taken into account.
