Do not make any voltage withstand tests on any part of the unit while the unit is connected. Disconnect motor cables before making any measurements on motors or motor cables. Close switch fuses of all parallel connected inverters before starting the drive. Do not open the drive section switch fuses when the inverter is running. Do not use Prevention of Unexpected Start for stopping the drive when the inverter is running.

Give a Stop command instead. Fans may continue to rotate for a while after the disconnection of the electrical supply. Some parts like heatsinks of power semiconductors and toroidal cores on motor cables inside the cabinet remain hot for a while after the disconnection of the electrical supply.

If an external source for start command is selected and it is ON, the drive will start immediately after fault reset. Frame size R11i and above must be supplied with a transformer dedicated to drives and motors or equipment of equal or higher power, or with a transformer equipped with two secondary windings, one of which is dedicated to drives and motors. Resonances might occur if there is capacitive load e. The resonance current might damage some unit in the network.

Click OK. Do you wish to associate it? MultiDrive be permanent? The DC voltage reference can be set also higher by a parameter. Two line currents and DC link voltage are measured and used for the control.

The control boards are similar to the boards of the inverter. Typical line current iU and voltage uUV waveforms are shown below. Spectrum of the Voltage A typical spectrum of the voltage distortion at the output of the DIstortion transformer is shown below. Each harmonic is presented as a percentage of the fundamental voltage. Each Current Distortion harmonic is presented as a percentage of the fundamental current. Two drive sections are drawn in the diagram, in reality the number of them varies.

The control panels are optional. This chapter describes the supply section. The diagrams below show the estimated voltage and current distortion as a function of short-circuit ratio. Please note that the curves are merely a visualisation of the effect of the LCL filter and supply network characteristics on the distortion, not a specification. The bridge is capable of delivering braking energy back to the network.

Frame size R11i includes six power plates and frame size R12i nine power plates. Configurations The sections below describe possible configurations of ISU modules. If one module fails, it can be disconnected by removing the fuses on both sides of it. The whole supply has a common disconnecting device. Full redundancy is not possible. The configuration is beneficial when the braking is continuous and the drive is not allowed to stop if the supply network trips for a short time.

Only qualified electricians are allowed to commission the drive. The Safety Instructions on the first pages of this manual must be followed. Ignoring the safety instructions can cause injury or death. Installation Checklist The installation must be checked before commissioning the supply section. This table refers to the more detailed instruction. Refer to checked according to instructions given in the Hardware Installation Checklist and Insulation Checks.

Ensure that the surroundings and inside of the cabinet are After the start, the cooling air fans may free from dust and loose objects like cable trimmings and suck nearby loose objects into the unit.

This might cause failure and damage the other waste left from the installation. Ensure that the disconnector of the supply transformer is locked to open position, i. Check also by measuring that there actually is no voltage connected. Air Circuit Breaker, Relays, Switches If the supply section is equipped with an air circuit breaker, The trip levels have been preset at the check the current trip levels of the air circuit breaker. In most applications there is no need to change these settings.

Floating Network This section describes the earth fault protection principle in a floating network. Insulation Monitoring Device Diagram This diagram shows earth fault protection implemented with an insulation monitoring device.

The measuring pulse consists of positive and negative pulses of the same amplitude. The period depends on the respective leakage capacitances and the insulation resistance of the system to be monitored. The setting of the response values and other parameters can be carried out via the function keys.

The parameters are indicated on the display and they are stored in a non-volatile memory after setting. Both values have an own alarm LED, which illuminates if reading is below these selected response values. In Case of an Earth Fault An earth fault closes the measuring circuit. An electronic evaluation circuit calculates the insulation resistance which is indicated on an LC display or an external ohmmeter after the response time. System-earthed In a system-earthed network, the neutral point of the supply Network transformer is earthed solidly.

This section describes an internal earth fault protection principle in a system-earthed network. Diagram This diagram shows earth fault protection implemented with internal current transducers in the ACA In Case of an Earth Fault In normal operation the current sum is zero.

An earth fault leads to an unbalance in the 3-phase system and therefore to a current sum different from zero. If the current unbalance exceeds the limit set in Par. Note: The parameters listed in this chapter need not be set in normal use. They are mentioned for explaining the control principle only. The following symbols are used: 1.

These parameters are not visible to the user unless the passcode is entered for the Parameter Lock in Parameter The DC voltage is controlled by keeping the power energy equilibrium between the line and the drives in the DC link constant. The sign of the angle determines the direction of the power flow. This is due to the fact that the existing voltage in the network can be thought to be generated by a rotating magnetic flux encircled by coils.
