operation, please read the
Operating Instructions Manual for
Safety Precautions and Warnings
SIEMENS MICROMASTER
The MICROMASTER products are a range of frequency
inverters for controlling the speed of three phase AC
induction motors
Step 1 Connecting up the MICROMASTER
230V Single Phase 400V Three Phase
Delta connection for
230V 3 phase
Star connection for
400V 3 phase
Note: Motors above 11kW are usually configured
400V Delta / 690V Star.
In this case the motor should be connected in Delta.
At any time, press the 'STOP' button and watch the
motor stop.
Step 3 Changing the speed of the motor
Step 2 Getting the motor going
The default output frequency of the drive is 5Hz (see
Hints and Tips to convert this to RPM). This speed will
probably be too low for most applications and a speed
change may be required. The following steps will allow
you to change the preset value of the inverter output to
the required speed.

Press the button 5 times until the display reads P005.
Press the 'P' button to display the current parameter value.
Press the button to change the value to 35Hz. (This
number can be any number between 0 and 50Hz - default.)
Press the 'P' button to store the new value.
Press the button until the display reads P000.
Press the 'P' button to exit the parameterisation procedure.
The display will alternate between the output frequency and
the frequency set point.
The required speed has now been stored.
This method is used to access all parameters.
The drive can now be started by pressing the 'RUN'
button. It will ramp up to the frequency held in parameter
P005 and remain there. To stop the drive press the
'STOP' button, the drive will then ramp down to 0Hz
output.

Step 4 Controlling the motor speed with
a potentiometer
A potentiometer can be used to control the running
speed of the inverter. This is achieved by varying the
voltage applied to the analogue input. Connect the
potentiometer to the control terminals shown below.
Starting and stopping of the motor may be achieved
by connecting a switch to the digital input terminals
shown.
P006 Set to 1 to allow analogue input
P007 Set to 0 to enable control via digital input
The following parameter settings are required
To get the best performance from your drive,
you should enter information from your motor
ratings plate into certain parameters. The
following diagram indicates the location of the
information and the parameters which should
be entered.

Hints and Tips
The direction of rotation of the motor can be
reversed during commissioning by changing
over two of the output connections on the
inverter, or by pressing the Forward/Reverse
button.
Parameters P000 to P009 can always be read
or set. Access to all other parameters is
controlled by the contents of P009. The
factory default value is '0' which only allows
access to P000 to P009. Changing its value
to '3' allows all parameters to be accessed
permanently. See Operator Manual for the
function of other values of P009.
In case there are problems with the parameter
settings and wish to start again, change P944
to '1'. This will perform a reset to the default
values.
The value displayed in P000 is the output
frequency of the inverter, this is the default
setting but it can be changed by altering the
value in P001. For example, changing P001
to a value of '5' will cause the inverter to
display the RPM of the motor in P000. See
the Operator Manual for other settings of
P001.
The default value (0) of parameter P006
ensures that the drive runs at the frequency
set in P005. In order to control the output
frequency by an analogue input signal, the
value of P006 should be set to '1'. For other
methods of control using P006, see the
Operator Manual.
An F002 fault is often caused by either too
short a ramp up time or too much voltage
boost. An increase in the value in P002 will
increase the ramp time. Alternatively lower
the values in P078 and P079 to reduce the
voltage boost. Please note that if P078 falls
below '100' (default value) then the motor
may under-perform at low frequencies.
An F001 fault is often caused by attempting to
stop the motor too quickly increasing the
value in P003 (ramp-down time) will reduce
this possibility.
If the display flashes during operation, the
drive is registering a warning. Check P931
for the cause.
