1 Overview
1.1
The MICROMASTER 420
The MICROMASTER 420s are a range of frequency inverters for controlling the
speed of three phase AC motors. The various models available range from the
120 W single phase input to the 11 kW three phase input.
The inverters are microprocessor-controlled and use state-of-the-art Insulated Gate
BipoIar Transistor (IGBT) technology. This makes them reliable and versatile. A
special pulse-width modulation method with selectable Pulse frequency permits
quiet motor operation. Comprehensive protective functions provide excellent
inverter and motor protection.
The MICROMASTER 420 with its default factory settings, is ideal for a large range
of simple motor control applications. The MICROMASTER 420 can also be used
for more advanced motor control applications via its comprehensive parameter
lists.
The MICROMASTER 420 can be used in both 'stand-alone' applications as well as
being integrated into 'Automation Systems'.

WARNING
The inverter must always be grounded.
♦
To ensure the safe operation of the equipment, it must be installed and
commissioned by qualified personnel in full compliance with the warnings laid
down in these operating instructions.
♦
Take particular note of the general and regional installation and safety
regulations regarding work on dangerous voltage installations (e.g. EN
50178), as well as the relevant regulations regarding the correct use of tools
and personal protective gear.
♦
Never use high voltage insulation test equipment on cables connected to the
inverter.
♦
The mains input, DC and motor terminals, can carry dangerous voltages even
if the inverter is inoperative; wait 5 minutes to allow the unit to discharge after
switching off before carrying out any installation work.
CAUTION
The control, power supply and motor leads must be laid separately. Do not feed
them through the same cable conduit/trunking.
2.4.1
General
WARNING
The inverter must always be grounded. If the inverter is not grounded correctly,
extremely dangerous conditions may arise within the inverter which could prove
potentially fatal.
Operation with ungrounded (IT) supplies
The MICROMASTER will operate from ungrounded supplies and will continue to
operate if an input phase is shorted to ground. If an output phase is shorted to
ground, the MICROMASTER will trip and indicate F0001.
On ungrounded supplies, it will be necessary to remove the ‘Y’ capacitor from the
inside of the unit and fit an output choke. The procedure for removing this capacitor
is described in Appendices 0 and 0.
Operation with Residual Current Device
If an RCD (also referred to as ELCB or RCCB) is fitted, the MICROMASTER
inverters will operate without nuisance tripping, provided that:
þ A type B RCD is used.
þ The trip limit of the RCD is 300mA.
þ The neutral of the supply is grounded.
þ Only one inverter is supplied from each RCD.
þ The output cables are less than 50m (screened) or 100m (unscreened).
Operation with long cables
All inverters will operate at full specification with cable lengths up to 50 m screened
or 100 m unscreened.

Power and motor connections
WARNING
The inverter must always be grounded.
♦ Isolate the mains electrical supply before making or changing connections to
the unit.
♦ Ensure that the motor is configured for the correct supply voltage: single /
three-phase 230 V MICROMASTERS must not be connected to a 400 V
three-phase supply.
♦ When synchronous motors are connected or when coupling several motors in
parallel, the inverter must be operated with voltage/frequency control
characteristic (P1300 = 0, 2 or 3).
CAUTION
After connecting the power and motor cables to the proper terminals, make sure
that the covers have been replaced properly before supplying power to the unit!
NOTICE
♦
♦
Ensure that the appropriate circuit-breakers/fuses with the specified current
rating are connected between the power supply and inverter (see chapter 7,
Tables starting on page 77).
o
Use Class 1 60/75 C copper wire only (for UL compliance). For tightening
torque see Table 7-2, page 76.
Access to the power and motor terminals
You can gain access to the mains and motor terminals by removing the covers
(see also Appendices 0, B und 0).
The mains and motor connections must be made as shown in Figure 2-6.

Avoiding Electro-Magnetic Interference (EMI)
The inverters are designed to operate in an industrial environment where a high
level of EMI can be expected. Usually, good installation practices will ensure safe
and trouble-free operation. If you encounter problems, follow the guidelines stated
below.
Action to Take
Ø
Ø
Ø
Ø
Ø
Ø
Ø
Ø
Ø
Ensure that all equipment in the cubicle is well grounded using short, thick
grounding cable connected to a common star point or busbar
Make sure that any control equipment (such as a PLC) connected to the
inverter is connected to the same ground or star point as the inverter via a
short thick link.
Connect the return ground from the motors controlled by the inverters directly
to the ground connection (PE) on the associated inverter
Flat conductors are preferred as they have lower impedance at higher
frequencies
Terminate the ends of the cable neatly, ensuring that unscreened wires are as
short as possible
Separate the control cables from the power cables as much as possible,
using separate trunking, if necessary at 90º to each other.
Whenever possible, use screened leads for the connections to the control
circuitry
Ensure that the contactors in the cubicle are suppressed, either with R-C
suppressors for AC contactors or 'flywheel' diodes for DC contactors fitted to
the coils. Varistor suppressors are also effective. This is important when the
contactors are controlled from the inverter relay
Use screened or armored cables for the motor connections and ground the
screen at both ends using the cable clamps
WARNING
Safety regulations must not be compromised when installing inverters!

♦
♦
MICROMASTERS operate at high voltages.
When operating electrical devices, it is impossible to avoid applying
hazardous voltages to certain parts of the equipment.
Emergency Stop facilities according to EN 60204 IEC 204 (VDE 0113) must
remain operative in all operating modes of the control equipment. Any
disengagement of the Emergency Stop facility must not lead to uncontrolled
or undefined restart.
Wherever faults occurring in the control equipment can lead to substantial
material damage or even grievous bodily injury (i.e. potentially dangerous
faults), additional external precautions must be taken or facilities provided to
ensure or enforce safe operation, even when a fault occurs (e.g. independent
limit switches, mechanical interlocks, etc.).
Certain parameter settings may cause the inverter to restart automatically
after an input power failure.
Motor parameters must be accurately configured for motor overload
protection to operate correctly.
This equipment is capable of providing internal motor overload protection in
2
accordance with UL508C section 42. Refer to P0610 and P0335, i t is ON by
default. Motor overload protection can also be provided using an external
PTC via a digital input.
This equipment is suitable for use in a circuit capable of delivering not more
than 10,000 symmetrical amperes (rms), for a maximum voltage of 230/460V
when protected by a time delay fuse (see Tables starting on page 77).
This equipment must not be used as an ‘emergency stop mechanism’ (see
EN 60204, 9.2.5.4)
CAUTION
Only qualified personnel may enter settings in the control panels. Particular
attention must be paid to safety precautions and warnings at all times.

External motor thermal overload protection
When operated below rated speed, the
cooling effect of fans fitted to the motor
shaft is reduced. Consequentially, most
motors require de-rating for continuous
operation at low frequencies. To ensure
that the motors are protected against
overheating under these conditions, a
PTC temperature sensor must be fitted to
the motor and connected to the inverter
control terminals. P0601 must also be set
to 1.

4.1
When operating electrical devices, it is impossible to avoid applying
hazardous voltages to certain parts of the equipment.
Emergency Stop facilities according to EN 60204 IEC 204 (VDE 0113) must
remain operative in all operating modes of the control equipment. Any
disengagement of the Emergency Stop facility must not lead to uncontrolled
or undefined restart.
Wherever faults occurring in the control equipment can lead to substantial
material damage or even grievous bodily injury (i.e. potentially dangerous
faults), additional external precautions must be taken or facilities provided to
ensure or enforce safe operation, even when a fault occurs (e.g. independent
limit switches, mechanical interlocks, etc.).
MICROMASTERS operate at high voltages.
Certain parameter settings may cause the inverter to restart automatically
after an input power failure.
Motor parameters must be accurately configured for motor overload
protection to operate correctly.
This equipment is capable of providing internal motor overload protection in
2
accordance with UL508C section 42. Refer to P0610 and P0335, i t is ON by
default. Motor overload protection can also be provided using an external
PTC via a digital input.
This equipment is suitable for use in a circuit capable of delivering not more
than 10 000 symmetrical amperes (rms), for a maximum voltage of 230/460V
when protected by a time delay fuse (see Tables starting on page 77).
This equipment must not be used as an ‘emergency stop mechanism’ (see
EN 60204, 9.2.5.4).

5.1
Introduction to MICROMASTER system parameters
The parameters can only be changed by using the BOP, the Advance
Operator Panel (AOP) or the Serial Interface.
Parameters can be changed and set using the BOP to adjust the desired
properties of the inverter, such as ramp times, minimum and maximum frequencies
etc. The parameter numbers selected and the setting of the parameter values are
indicated on the optional five-digit LCD display.
Ø rxxxx indicates a display parameter, Pxxxx a setting parameter.
Ø P0010 initiates “quick commissioning”.
Ø The inverter will not run unless P0010 is set to 0 after it has been accessed.
This function is automatically perform if P3900 > 0.
Ø P0004 acts as a filter, allowing access to parameters according to their
functionality.
Ø If an attempt is made to change a parameter that cannot be changed in this
status, for example, cannot be changed whilst running or can only be changed
Ø
in quick commissioning, then
will be displayed.
Busy Message
In some cases - when changing parameter values - the display on the BOP
shows
for maximum of five seconds. This means the inverter is busy
with tasks of higher priority.
5.1.1
Level
There are four levels of user access, Standard, Extended, Expert and Service
selectable by parameter P0003. For most applications, Standard (P0003 = 1) or
Extended parameters (P0003 = 2) are sufficient.
The number of parameters that appear within each functional group depends on
the access level set in parameter P0003. For further details regarding parameters,
see the Parameter List on the Documentation CD-ROM.

Troubleshooting with the BOP
Warnings and faults are displayed on the BOP with Axxx and Fxxx respectively.
The individual messages are shown in Section 6.3.
If the motor fails to start when the ON command has been given:
Ø Check that P0010 = 0.
Ø Check that a valid ON signal is present.
Ø Check that P0700 = 2 (for digital input control) or
P0700 = 1 (for BOP control).
Ø Check that the setpoint is present (0 to 10V on Terminal 3) or the setpoint has
been entered into the correct parameter, depending upon the setpoint source
(P1000). See the Parameter List for further details.
If the motor fails to run after changing the parameters, set P0010 = 30 then P0970
= 1 and press P to reset the inverter to the factory default parameter values.
Now use a switch between terminals 5 and 8 on the control board. The drive
should now run to the defined setpoint by analogue input.
NOTICE
Motor data must relate to the inverter data power range and voltage.

Vdc max controller has been deactivated, since controller is not
capable of keeping DC-link voltage
(r0026) within limits (P2172)
Ø Occurs if main supply voltage
(P0210) is permanently too high
Ø Occurs if motor is driven by an
active load, causing motor to
goes into regenerative mode
Ø Occurs at very high load inertias,
when ramping down
Vdc max controller is active; so rampdown times will be increased
automatically to keep DC-link voltage
(r0026) within limits (P2172)
Vdc min controller will be activated if
DC-link voltage (r0026) falls below
minimum level (P2172)
Ø The kinetic energy of the motor is
used to buffer the DC-link
voltage, thus causing
deceleration of the drive!
Ø So short mains failures do not
necessarily lead to an
undervoltage trip
ADC parameters should not be set to
identical values, since this would
produce illogical results.
Ø Index 0: Parameter settings for
output identical
Ø Index 1: Parameter settings for
input identical
Ø Index 2: Parameter settings for
input do not correspond

Ø Index 0: Parameter settings for

Ø No Load is applied to the inverter
Ø As a result, some functions may
not work as under normal load
conditions
Low output voltage eg when 0 boost
applied at 0 Hz
Check the following:
1. Input voltage (P0756) lies within range?
2. Load must match

9.1
Electro-magnetic compatibility (EMC)
All manufacturers / assemblers of electrical apparatus which “performs a complete
intrinsic function and is placed on the market as a single unit intended for the end
user” must comply with the EMC directive 89/336/EEC.
There are three routes for the manufacturer/assembler to demonstrate compliance:
9.1.1
Self-certification
This is a manufacturer's declaration that the European standards applicable to the
electrical environment for which the apparatus is intended have been met. Only
standards that have been officially published in the Official Journal of the European
Community can be cited in the manufacturer's declaration.
9.1.2
Technical construction file
A technical construction file can be prepared for the apparatus describing its EMC
characteristics. This file must be approved by a ‘Competent Body’ appointed by the
appropriate European government organization. This approach allows the use of
standards that are still in preparation.
9.1.3
EC type examination certificate
This approach is only applicable to radio communication transmitting apparatus. All
MICROMASTER units are certified for compliance with the EMC directive, when
installed in accordance with the recommendations in Section 2.

EMC Directive Compliance with Imminent Harmonics
Regulations
From 1st January 2001 all electrical apparatus covered by the EMC Directive will
have to comply with EN 61000-3-2 "Limits for harmonic current emissions
(equipment input ≤ 16 A per phase)".
All Siemens variable speed drives of the MICROMASTER, MIDIMASTER,
MICROMASTER Eco and COMBIMASTER ranges, which are classified as
"Professional Equipment" within the terms of the standard, fulfill the requirements
of the standard.
Special considerations for 250 W to 550 W drives with 230 V 1ac mains supplies
when used in non-industrial applications
Units in this voltage and power range will be supplied with the following warning:
”This equipment requires supply authority acceptance for connection to the public
supply network”. Please refer to EN 61000-3-12 sections 5.3 and 6.4 for further
information. Units connected to Industrial Networks1 do not require connection
approval (see EN 61800-3, section 6.1.2.2).
The harmonic current emissions from these products are described in the table
below:

The allowed harmonic currents for “professional equipment” with an input power
> 1 kW are not yet defined. Therefore, any electrical apparatus containing the
above drives which has an input power > 1 kW will not require connection
approval.
Alternatively, the necessity to apply for connection approval can be avoided by
fitting the input chokes recommended in the technical catalogues (except 550 W
230 V 1ac units).
1 Industrial Networks are defined as those which do not supply buildings used for domestic purposes.
