1. DESCRIPTION
SIMOVERT P transistorised voltage–source inverters operate with high voltages.
Connection, commissioning and fault–finding should only be carried out by qualified personnel
who are fully conversant with the relevant documentation, installation regulations, etc.
Only permanently–wired input power connections are allowed. This equipment must be
grounded (IEC 536 Class 1, NEC and other applicable standards).
Safety Note:
Do not apply input power to the equipment when the plastic cover has been removed.
Dangerousvoltagesarepresentwithintheequipmentwhichcouldcauseseriousinjuryordeath
iftouched.After removing mains power,always allow a minimum of five minutes for the internal
capacitors to discharge before removing the cover.
When the 3–phase mains input is protected by a current–operated earth–leakage breaker, the
inputtothe innverter must be isolated from the mains if the earth–leakage breaker is tooperate
effectively.
The dc–link capacitors remain charged to dangerous voltages for up to five minutes after the
incoming power has been switched off.

AND motor output terminals and also on the dc–link terminals.
Under certain set–up conditions, the inverter may restart automatically after an input power
failure.
WARNING
1.1 Introduction
SIMOVERTPinvertersofthe6SE21seriesaredesignedforlow–lossspeedcontrolofthree–phasemotors.This
is achieved by rectifying input voltage to establish a dc link voltage, and modulating this link voltage with a
three–phase transistor bridge to produce a Pulse–Width Modulated (PWM) three–phase output voltage
(see
Figure 1) . The inductance of the motor windings converts this PWM voltage to a sinusoidal motor current. By
varying the frequency of this sinusoidal current, the rotational speed of the motor is controlled without
significantly affecting the losses in the motor. The output frequency can be adjusted between 0 and 400 Hz.

1.4.2 Low Frequency Voltage Boost (Ku)
Theoutput voltage canbe boosted in0.1% stepsupto 30%for lowfrequenciesfrom 0Hz. Thismaybe required
to give additional starting torque in some applications. The amount of voltage boost decreases linearly until
100% voltage is achieved.
If required, automatic boost may be used
(see section 5.3.2, Parameter P19) . This measures the motor
characteristics and selects a suitable boost voltage at first switch–on.
1.4.3 Current Limit
The maximum output current available from the inverter can be adjusted to provide thermal protection of the
motor and/or limit the maximum motor torque
(see section 5.3.2, parameters P17 and P18) .

Inverters suitable for use with single phase supplies are fitted with three input terminals (X1.L1, X1.N and X1. ).
Those suitable for use with three phase supplies have four input terminals (X1.L1, X1.L2, X1.L3 and X1. ).
Connect the motor to terminals X1.U, X1.V and X1.W, ensuring that the motor is correctly connected for the
inverteroutput voltage. For singlephaseinverters, the motorwindingswill normally need tobeconnected in delta
form.
Once the cables have been installed, route them through the rubber cable grommets or, if required, use a
proprietary cable gland.
4.2 Control Connections
Make the control connections to the top board (X11) using shielded cable for analogue signals. After installation,
route the control cable through the right–hand cable grommet or, if required, use a proprietary cable gland.
The control cable should be routed separately from the power supply and motor cables.
The control wires must not run in the same cable duct/trunking as the motor output
cables.
IMPORTANT
Refit the drive’s plastic cover.
Figure 4 shows an example of an inverter with typical control connections made. Other control configurations are
described in section 5.

Hazardous voltages of over 750 V are used in the operation of this equipment.
Read the Warning Notice given at the start of section 4 before proceeding further.
WARNING
Thefactorysettingof 6SE21–seriesinvertersallowsthemtobeusedimmediatelyinmanyapplications.However,
matchingtospecificapplicationscanbeaccomplishedeasilybyusingthewiderangeofdigitalparametersettings
provided (see section 5.3) .
5.1 Preparation for Switch–On
All the features of the 6SE21 inverter may be controlled via the RS485 serial interface (see
section 7)
. If this is how the inverter is to be used, remember that it may start and stop without
warning. Appropriate precautions must be taken to prevent accidents from occurring while the
inverter is being controlled in this manner.
If the inverter is to be operated by external remote controls connected via terminal block X11,
disablethe integral controls to avoidmisleading operation and possible damage to the inverter.
CAUTION
Ensure that the cover is fitted correctly before switching on the inverter.
Wait at least five minutes after switching off before attempting to remove the plastic cover and
work on the equipment. This will allow time for the capacitors within the unit to discharge to a
safe level.
Failure to observe these precautions may result in serious injury or death.

5.1.1 Starting and Stopping the Inverter
This equipment uses dangerous voltages and controls rotating mechanical machinery.
Dangerous voltages are present on the equipment even after switching off. Isolate elsewhere
before attempting to work on the equipment.
Under certain operating conditions the inverter can restart automatically after an input power
failure.Ensurethatnooneisclosetomachinerycontrolledbytheinverterwhensuchconditions
prevail.
DEATH or SERIOUS INJURY can result if the above precautions are not observed.
WARNING
The method of starting and stopping the inverter depends on the setting of parameter P05. One of three different

Siemens plc 1993
Donotrestartthe inverter or reconnect it to a motor which is already running. Wait for the motor
to stop and the inverter to reach zero output frequency before attempting to run the
motor/inverter combination again.
CAUTION
The three run–down modes operate as follows:
Ramp–Down (P05 = 000, 004, 006 or 008)
The inverter output frequency will ramp–down at a rate set by parameter P03 until the minimum output
frequency (set by P07) is reached. At this point the inverter stops with no output.
Free Run (P05 = 002, 003, 005, 007 or 009)
Theinverteroutput stops immediately, allowing the motor to‘freewheel’toa standstill or tobestopped by
other means.
DC Injection Brake
DCinjectionbrakingisselectedbysettingparameterP11toavaluegreaterthanzero.Theinverterinjects
dc into the motor for a period equivalent to the ramp–down time set by P03 plus one second.
5.1.2 Direction of Rotation
Thedirection ofmotorrotation canbe reversedbyapplying avoltage level ofgreater than+7V toterminal 5ofthe
controlboard. This can be achieved by connecting ashort–circuitbetweenterminals2and5 on the control board
or applying an external control voltage of 7 – 33 V. If no connection is made, the output phase rotation will be
clockwise.
5.1.3 Jog Feature
The inverter may be run up to a predetermined frequency (set via parameter P12) by applying an external control
voltageof7–33Vtoterminal13onthecontrolboard,orbyconnectingapush–buttonbetweenterminals2and13
onthecontrolboard.Themotorwillonlyrunwhilethisvoltageisapplied,andtheinputisonlyactivewhenthedrive

The jog feature may be used for fine adjustment or ‘inching’ of equipment.
5.1.4 Speed Control
The motor speed is adjusted by the frequency set–point. This can be adjusted by analogue means (0 –10 V on
terminalX11.7or0–20mA/4–20mAonterminalX11.9)ordigitallybythepush–buttonslocatedbehindthefront
panel access clip. These push–buttons may be duplicated by connecting push–buttons to terminals X11.16,
X11.17 and X11.18
(see Figure 4) . A 10 V reference output is provided on terminal X11.6 so that an external
potentiometer can be used. Certain fixed frequency modes may also be selected (see section 5.3.2) .
