Technical data 14(86) 4. TECHNICAL DATA 4.1 Introduction Figure 4-1 presents the block diagram of the NX frequency converter. The frequency converter consists of two units, the Power Unit and the Control Unit. The three-phase AC-choke (1) at the mains end together with the DC-link capacitor (2) form an LC-filter, which, again, together with the diode bridge produce the DC-voltage supply to the IGBT Inverter Bridge (3) block.
PAGE 15
Technical data 15(86) The control keypad provides a link between the user and the frequency converter. The control keypad is used for parameter setting, reading status data and giving control commands. It is detachable and can be operated externally and connected via a cable to the frequency converter. Also a PC can be used instead of the control keypad, to control the frequency converter, if connected through a similar cable.

Installation 5. 19(86) INSTALLATION 5.1 Mounting The frequency converter can be mounted in either vertical or horizontal position on the wall or on the back plane of a cubicle. Enough space shall be reserved around the frequency converter in order to ensure a sufficient cooling, see Figure 5-6, Table 5-6 and Table 5-7. For safe installation, ensure that the mounting surface is relatively even. The frequency converter should be fixed with four screws (or bolts, depending on the unit size).

Installation 25(86) 5.2 Cooling Enough free space should be left around the frequency converter to ensure sufficient air circulation and cooling. The required dimensions for free space are in the table below. If several units are mounted above each other the required free space equals C + D (see figure below). Moreover, the outlet air used for cooling by the lower unit must be directed away from the inlet air to be used by the upper unit.

Cabling and connections 30(86) 6.1.1 Power connections Use cables with heat resistance of at least +60°C. The cables and the fuses must be dimensioned according to the frequency converter nominal OUTPUT current which can be found on the rating plate. Dimensioning according to the output current is recommended because the frequency converter input current never significantly exceeds the output current. Installation of cables according to UL regulations is presented in Chapter 6.1.3.

Commissioning 8. 81(86) COMMISSIONING 8.1 Safety Before commissioning, note the following directions and warnings: 1 2 3 4 5 WARNING 6 Internal components and circuit boards of the frequency converter (except for the galvanically isolated I/O terminals) are live when the NX is connected to mains potential. Coming into contact with this voltage is extremely dangerous and may cause death or severe injury.
PAGE 82
Commissioning 82(86) 7 Set the parameters of group 1 (See the Application Manual) according to the requirements of the application. At least the following parameters should be set: - motor nominal voltage motor nominal frequency motor nominal speed motor nominal current The values needed for the parameters are on the motor rating plate. 8 Perform run test without motor Perform either Test A or Test B: A Controls from the I/O terminals: a) Turn the Start/Stop switch to ON position.

Fault tracing FAULT TRACING When a fault is detected by the frequency converter control electronics, the drive is stopped and the symbol F together with the ordinal number of the fault, the fault code and a short fault description appear on the display. The fault can be reset with the Reset button on the control keypad or via the I/O terminal. The faults are stored in the Fault history menu (M5) which can be browsed. The different fault codes can be found in the table below.
