1. OVERVIEW
The MICROMASTERS are a range of frequency inverters for controlling the speed of three phase AC motors.
Various models are available, ranging from the compact 120 W single phase input MICROMASTER up to the 7.5
kW three phase input MICROMASTER.
The inverters are microprocessor-controlled and use state of the art IGBT technology for reliability and
flexibility. A special pulse-width modulation method with selectable ultrasonic pulse frequency permits
extremely quiet motor operation. Inverter and motor protection is provided by comprehensive protective
functions.
Features:
• Easy to install, program and commission.
• Closed loop control using a Proportional, Integral (PI) control loop function.
• High starting torque with automatic starting boost.
• Remote control capability via RS485 serial link using the USS protocol with the ability to control up to 31
inverters.
• A comprehensive range of parameters is provided to enable the inverters to be configured for use in
almost any application.
• Membrane-type front panel controls for simple operation.
• Built-in non-volatile memory for storing parameter settings.
• Factory default parameter settings pre-programmed for European and North American requirements.
• Output frequency (and hence motor speed) can be controlled by one of five methods:
(1) Frequency setpoint using the keypad.
(2) High resolution analogue setpoint (voltage input).
(3) External potentiometer to control motor speed.
(4) Fixed frequencies via binary inputs.
(5) Serial interface.
• Built-in DC injection brake with special COMPOUND BRAKING.
• Integral RFI filter on single phase input inverters (MM12 - MM300).
• Acceleration/deceleration times with programmable smoothing.
• Fully programmable single relay output incorporated.
• External Options connector for optional multi-language Clear Text Display (OPM2) or optional PROFIBUS
module.
• Automatic recognition of 2, 4, 6 or 8-pole motors by software.
• Integral software-controlled cooling fan.
• Fast Current Limit (FCL) for reliable trip-free operation.
• Compact design and the ability to mount inverters side by side provides greater space saving.
2.1 Wiring Guidelines to Minimi se the Effects of EMI
The inverters are designed to operate in an industrial environment where a high level of Electro-Magnetic
Interference (EMI) can be expected. Usually, good installation practices will ensure safe and trouble-free
operation. However, if problems are encountered, the following guidelines may prove useful. In particular,
grounding of the system 0V at the inverter, as described below, may prove effective. Figure 1 illustr ates how
an RFI suppression filter should be installed.
(1)Ensure that all equipment in the cubicle is well earthed using short, thick earthing cable connected to
a common star point or busbar. It is particularly important that any control equipment that is
connected to the inverter (such as a PLC) is connected to the same earth or star point as the inverter
via a short, thick link. Flat conductors (e.g. braids or metal brackets) are preferred as they have lower
impedance at high frequencies.
The return earth from motors controlled by the inverters should be connected directly to the earth
connection (PE) on the associated inverter.
(2)Wherever possible, use screened leads for connections to the control circuitry. Terminate the ends of
the cable neatly, ensuring that unscreened wires are as short as possible. Use cable glands
whenever possible.
(3)Separate the control cables from the power connections as much as possible, using separate
trunking, etc. If control and power cables cross, arrange the cables so that they cross at 90° if
possible.
(4)Ensure that 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 particularly important if the contactors are controlled from the relay on the inverter.
(5)Use screened or armoured cables for the motor connections and ground the screen at both ends via
the cable glands.
(6)If the drive is to be operated in an Electro-magnetic noise-sensitive environment, the RFI footprint
filter kit should be used to reduce the conducted and radiated interference from the inverter. For
optimum performance, there should be a good conductive bond between filter and metal mounting
plate.
On no account must safety r egulations be compromised when installing inverters!

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
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 as shown in Figure 7.
Note:To enable the trip function, set parameter P051, P052 or P053 =19.
The digital frequency setpoint has been set at 5.00 Hz in the factory. This means that, it is not
necessary to enter a frequency setpoint via the ∆ button or parameter P005 in order to test
that the motor turns following a RUN command.
All settings must only be entered by qualified personnel, paying particular attention to the
safety precautions and warnings.

3.2 Basic Operation
Refer to section 5 for a full description of each parameter.
3.2.1 General
(1) The inverter does not have a main power switch and is live when the mains supply is connected. It waits,
with the output disabled, until the RUN button is pressed or for the presence of a digital ON signal at
terminal 5 (rotate right) or terminal 6 (rotate left) -
(2) If output frequency is selected to be displayed (P001 = 0), the corresponding setpoint is displayed
approximately every 1.5 seconds while the inverter is stopped.
(3) The inverter is programmed at the factory for standard applications on Siemens four-pole standard
motors. When using other motors it is necessary to enter the specifications from the motor’s rating plate
into parameters P081 to P085

4. OPERATING MODES
4.1 Digital Cont rol
For a basic startup configuration using digital control, proceed as follows:
(1) Connect control terminal 5 to terminal 8 via a simple on/off switch. This sets up the motor for clockwise
rotation (default).
(2) Apply mains power to the inverter. Set parameter P009 to 002 or 003 to enable all parameters to be
adjusted.
(3) Check that parameter P006 is set to 000 to specify digital setpoint.
(4) Set parameter P007 to 000 to specify digital input (i.e. DIN1 (terminal 5) in this case) and disable the front
panel controls.
(5) Set parameter P005 to the desired frequency setpoint.
(6) Set parameters P081 to P085 in accordance with the rating plate on the motor
Note:In many cases, when default factory parameters are used, the default stator resistance set in
P089 will generally suit the default power rating set in P085. Should the inverter and motor
ratings differ greatly, it is recommended that the stator resistance of the motor is measured and
entered manually into P089. Continuous Boost (P078) and Starting Boost (P079) are dependent
on the value of Stator Resistance - too high a value may cause overcurrent trips
(7) Set the external on/off switch to ON. The inverter will now drive the motor at the frequency set by P005.
(see Figure 10)
.
4.2 Analogue Control
For a basic startup configuration using analogue voltage control, proceed as follows:
(1) Connect control terminal 5 to terminal 8 via a simple on/off switch. This sets up the motor for clockwise
rotation (default).
(2) Connect a 4.7 kΩ potentiometer to the control terminals as shown in Figure 6 or connect pin 2 (0V) to pin
4 and a 0 - 10 V signal between pin 2 (0V) and pin 3 (AIN+).
(3) Apply mains power to the inverter. Set parameter P009 to 002 or 003 to enable all parameters to be
adjusted.
(4) Set parameter P006 to 001 to specify analogue setpoint.
(5) Set parameter P007 to 000 to specify digital input (i.e. DIN1 (terminal 5) in this case) and disable the front
panel controls.
(6) Set parameters P021 and P022 to specify the minimum and maximum output frequency settings.
(7) Set parameters P081 to P085 in accordance with the rating plate on the motor
Note:In many cases, when default factory parameters are used, the default stator resistance set in
P089 will generally suit the default power rating set in P085. Should the inverter and motor
ratings differ greatly, it is recommended that the stator resistance of the motor is measured and
entered manually into P089. Continuous Boost (P078) and Starting Boost (P079) are dependent
on the value of Stator Resistance - too high a value may cause overcurrent trips
(8) Set the external on/off switch to ON. Turn the potentiometer (or adjust the analogue control voltage) until
the desired frequency is displayed on the inverter.
• Cancelling the ON command or pressing the OFF button (O) on the front panel causes the inverter to
ramp down at the selected ramp down rate
• OFF2 - operation causes the motor to coast to a standstill
• OFF3 - operation causes rapid braking
• DC injection braking up to 250% causes a rapid stop

.
4.4 If the Motor Does Not Start Up
If the display shows a fault code, refer to Section 6.
If the motor does not start up when the ON command has been given, check that the ON command is valid,
check if a frequency setpoint has been entered in P005 and check that the motor specifications have been
entered correctly under parameters P081 to P085.
If the inverter is configured for operation via the front panel (P007 = 001) and the motor does not start when
the RUN button is pressed, check that P121 = 001 (RUN button enabled).
If the motor does not run after parameters have been changed accidentally, reset the inverter to the factory
default parameter values by setting parameter P944 to 001 and then pressing P.
4.5 Local and Remote Control
The inverter can be controlled either locally (default), or remotely via a USS data line connected to the RS485
D-type connector on the front panel. (Refer to parameter P910 in section 5 for the available remote control
options.)
When local control is used, the inverter can only be controlled via the front panel or the control terminals.
Control commands, setpoints or parameter changes received via the RS485 interface have no effect.
When operating via remote control the inverter will not accept control commands from the terminals.
Exception: OFF2 or OFF3 can be activated via parameters P051 to P053 (refer to parameters P051 to P053
in section 5).
Several inverters can be connected to an external control unit at the same time. The inverters can be
addressed individually.

4.6 Closed Loop Control
4.6.1 General Description
The MICROMASTER provides a PI control function for closed loop control
for temperature or pressure control, or other applications where the controlled variable changes slowly or
where transient errors are not critical. This control loop is not suitable for use in systems where fast response
times are required.
Note:The closed loop function is not designed for speed control, but can be used for this provided that fast
response times are not required.
When closed loop PI control is enabled (P201 = 002), all setpoints are calibrated between zero and 100%, i.e.
a setpoint of 50.0 = 50%. This allows general purpose control of any process variable that is actuated by
motor speed and for which a suitable transducer is available.

closed loop control are shown in Figure 11. Other parameters which are also associated with closed loop
control are as follows:
Descriptions of all closed loop control parameters are provided in section 5. For further detailed information
about PI operation refer to the Siemens DA 64 Catalogue.
Parameters can be changed and set using the membrane-type buttons 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 in the four digit LED display.
Note:If you press the ∆ or ∇ button momentarily, the values change step by step. If you keep the buttons
pressed for a longer time, the values scroll through rapidly.
Access to parameters is determined by the value set in P009. Check that the key parameters necessary for
your application have been programmed.
Note:In the following parameter table:
‘•’Indicates parameters that can be changed during operation.
‘
’ Indicates that the value of this factory setting depends on the rating of the inverter.
To increase the resolution to 0.01 when changing frequency parameters, instead of pressing P momentarily
to return to the parameter display, keep the button pressed until the display changes to ‘- -.n0’ (n = the
current tenths value, e.g. if the parameter value = ‘055.8’ then n = 8). Press ∆ or ∇ to change the value (all
values between .00 and .99 are valid) and then press P twice to return to the parameter display.
If parameters are changed accidentally, all parameters can be reset to their default values by setting
parameter P944 to 1 and then pressing P.

Allows the inverter to start onto a spinning mot or.
Under normal circumstances the inverter runs t he mot or up from 0 Hz.
However, if the motor is still spinning or is being driven by the load, it will
undergo braking before running back up to the setpoint - this can cause an
overcurrent trip. By using a f lying rest art, the in verter ‘hom es in’ on t he
motor's speed and runs it up from that speed to t he setpoint . Note: If the
motor has stopped or is rotat ing slowly, some ‘rocking’ may occur as the

(2)Setting P063 or P064 to t oo high a value, especially
with P012 set to a high value, can cause an
overcurrent warning or trip as the inverter attempts to
move a locked motor shaft.
P065
Current threshold for relay (A )0 - 99.9
[1.0]
This parameter is used when P061 = 9. The relay switches on when
the motor current is greater than the value of P065 and switches off
when the current falls to 90% of the value of P065 (hysteresis).
0 = Off
1 = On. Permits faster ramp-down times and enhances stopping
capability.
This stops the motor by applying a DC current. This causes heat to be
generated in the motor rather than t he invert er and holds t he shaf t
stationary until the end of the braking period. Braking is effective for the
period of time set by P003.
The DC brake can be activated using DIN1 - DIN3 (braking is active foras long as the DIN is high - see P051 - P053).
WARNING: Frequent use of long periods of dc inj ection braking
can cause the motor to overheat.
If DC injection braking is enabled via a digital i nput
then DC current is applied for as long as the digital
input is high. This causes heat in the motor.
0 = Disabled
1 = Enabled. Causes an F074 trip if the motor exceeds the I2t calculation.
The time taken to tri p is dependent on t he dif ference between t he
overload current and the nominal mot or current rating st ored in P 083 typically a 150% overload will result in a switch-off in 1 - 2 minutes.
WARNING: Where motor thermal pro tectio n is requ ired , an external
PTC must be used.
Sets the pulse frequency (from 2 to 16 kHz) and the PWM mode. I f
silent operation is not absolutely necessary, the losses in the inverter
as well as the RFI emissions can be reduced by selecting lower pulse
frequencies.
0/1 = 16 kHz (230 V default)
2/3 =8 kHz
4/5 = 4 kHz (400 V default)
6/7 =2 kHz
Note:When P 076 = 0/1, the display of the current at frequencies
below 10 Hz is less accurate.
400V inverters require the continuous current rating reduced for
operation below 5Hz, when operating at switching frequencies greater
than 4kHz and with boost values greater than 100% (P078 + P079).

Operates continuously over the whole frequency range.
For many applications it is necessary to increase low frequency torque.
This parameter sets the start-up voltage at 0 Hz to adjust the available
torque for low frequency operation. 100% setting will produce rated
motor current at low frequencies.
WARNING:If P078 is set too high, o verh eating of the motor
and/or an overcurrent trip (F002) can occur.
For drives which require a high initial starting torque, it is possible to
set an additional current (added to the setti ng in P078) during ramping.
This is only effective during initial start up and until the frequency
setpoint is reached.
Note:This increase is in addition to P078.

Description / Notes
Specific to PROFIBUS-DP . See PROFIBUS Handbook for furt her
details.
Access only possible with P099 = 1
0 = Changes to parameter settings (including P971) are lost when
power is removed.
1 = Changes to parameter settings are retained during periods
when power is removed.
WARNING: When using the serial link to update the parameter
set held in EEPROM, care must be taken not to
exceed the maximum number of wri te cycl es to thi s
EEPROM - this is approximately 50,000 write cycles.
Exceeding this number of write cycles would result
in corruption of the stored data and subsequent
data loss. The number of read cycles are unlimited.
In the event of a failure, the inverter switches off and a fault code appears on the display. The last fault that
occurred is stored in parameter P930. e.g. ‘0003’ indicates that the last error was F003.

8. SUPPLEMENTARY INFORMATI ON
8.1 Application Example
Setup procedure for a simple application
Motor:220 V
1.5 kW output power
Application requirements:Setpoint adjustable via potentiometer 0 - 50 Hz
Ramp up from 0 to 50 Hz in 15 seconds
Ramp down from 50 to 0 Hz in 20 seconds
Inverter used:MM150 (6SE9216-8BB40)
Settings:P009 = 2 (all parameters can be altered)
P081 - P085 = values given on motor rating plate
P006 = 1 (analogue input)
P002 = 15 (ramp up time)
P003 = 20 (ramp down time)
This application is now to be modified as follows:
Operation of motor up to 75 Hz
(voltage/frequency curve is linear up to 50 Hz).
i.e.
Motor potentiometer setpoint in addition to
analogue setpoint .
Use of analogue setpoint at maximum 10 Hz.
Ramp times to remain the same.
Parameter adjustments:P009 = 2 (all parameters can be altered)
P013 = 75 (maximum motor frequency in Hz)
P006 = 2 (setpoint via motor potentiometer or fixed setpoint)
P024 = 1 (analogue setpoint is added)
P022 = 10 (maximum analogue setpoint at 10 V = 10 Hz)
8.2 USS Status Codes
The following list gives the meaning of status codes displayed on the front panel of the inverter when the
serial link is in use and parameter P001 is set to 006:
001Message OK
002Slave address received
100Invalid start character
101Timeout
102Checksum error
103Incorrect message length
104Parity fail
Notes
(1)The display flashes whenever a byte is received, thus giving a basic indication that a serial link
connection is established.
(2)If ‘100’ flashes on the display continuously, this usually indicates a bus termination fault.
All manufacturers / assemblers of electrical apparatus which performs a complete intrinsic function which is
placed on the market as a single unit intended for the end user must comply with the EMC directive
EEC/89/336 after January 1996. There are three routes by which the manufacturer/assembler can
demonstrate compliance:
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 which have been
officially published in the Official Journal of the European Community can be cited in the
manufacturer’s declaration.
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 organisation. This approach allows the use of standards which are still in preparation.
3.
EC Type-Examination Certificate
This approach is only applicable to radio communication transmitting apparatus.
The MICROMASTER units do not have an intrinsic function until connected with other components (e.g. a
motor). Therefore, the basic units are not allowed to be CE marked for compliance with the EMC directive.
However, full details are provided below of the EMC performance characteristics of the products when they
are installed in accordance with the wiring recommendations in section 2.1.
Three classes of EMC performance are available as detailed below. N ote that these levels of performance are only
achieved when using the default switching frequency (or less) and a maxi mum motor cable length of 25 m.
Class 1: General Industrial
Compliance with the EMC Product Standard for Power Drive Systems EN 68100-3 for use in Second
Environment (Industrial) and Restricted Distribution.
Electrostatic DischargeEN 61000-4-28 kV air discharge
Burst InterferenceEN 61000-4-42 kV power cables, 1 kV control
Radio Frequency Electromagnetic FieldIEC 1000-4-326-1000 MHz, 10 V/m
* Limits not required inside a plant
where no other consumers are
connected to the same electricity
supply transformer.

8.4 Environmental Aspects
Transport and Stor age
Protect the inverter against physical shocks and vibration during transport and storage. The unit must also be
protected against water (rainfall) and excessive temperatures
The inverter’s packaging is re-usable. Retain the packaging or return it to the manufacturer for future use.
(see section 7).
If the unit has been in storage (non-operational) for more than one year, you must re-form the DC-link
capacitors before use. Refer to your local Siemens sales office for advice on the procedure.
Dismantling and Di sposal
The unit can be broken-down to its component parts by means of easily-released screw and snap
connectors.
The component parts can be re-cycled, disposed of in accordance with local requirements or returned to the
manufacturer.
Documentation
This handbook is printed on chlorine-free paper which has been produced from managed sustainable forests.
