1.2 Wiring Guidelines to Minimise 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. If problems are encountered, the following
guidelines may prove useful. In particular, grounding of the system at the inverter, as described below, may prove effective. Figures
1.2.1-1.2.3 illustrate how an RFI suppression filter should be installed and connected to the MICROMASTER Vector.
(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 inverter should be connected directly to the earth connection (PE) on the
associated inverter.
(2)On the MIDIMASTER Vector, use saw-tooth washers when mounting the inverter and ensure that a good electrical
connection is made between the heatsink and the panel, removing paint if necessary.
(3)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.
(4)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.
(5)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.
(6)Use screened or armoured cables for the motor connections and ground the screen at both ends via the cable glands.
(7) If the drive is to be operated in an Electro-magnetic noise-sensitive environment, the RFI filter 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.
(8) For Frame Size A units (Fig.1.2.1), the flat earth braid strap, supplied with the unit, should be fitted to minimise emissions.
Fix motor and control cable screen
securely to metal back plate using
suitable clips.

1.3 Electrical Installation - General Notes
1.3.1 Operation with Unearthed (IT) Supplies
MICROMASTER / MIDIMASTER Vector were developed for operation on grounded line supplies. These drive units can
also be operated on non-grounded line supplies. However, we do not recommend this. However, if the drive units are
operated on non-grounded line supplies, then the following points must be carefully observed:
· It is mandatory that line reactors are used.
· They are used to adapt line impedances and to minimize voltage peaks.
· It is also mandatory to use output reactors.
· The max. line supply voltage is 500V (the ±10% specified only refers to the range which is used to absorb voltage
peaks)
· The drive unit is not shut down when ground faults occur on the incoming side.
· The drive unit is shutdown with fault F002 (overcurrent) if one or several output conductors develop a ground fault.
· Every drive unit has electronics which are grounded and which result in a ~ 20mA ground fault current.
· The maximum clock cycle frequency is 2kHz.
· Only non-filtered drive units may be used.
· When operated at more than 40 Hz or briefly before full-load operation, the MIDIMASTER can be shut down with an
overcurrent message.
·We recommend that ground fault monitoring devices are used at the incoming supply which can detect ground faults
at the drive converter output
If necessary, an insulating transformer should be used
1.3.2 The use of residual-current protective devices
Drive inverters can be operated with residual-current protective devices under the following conditions:
· 1-phase:
Residual-current protective devices with 300mA (type A) are permissible
· 3-phase:
Universal residual-current protective device with 300mA (type B) must be used.
· Only one drive inverter may be connected to a residual-current protective device.
· The neutral conductor of the line supply must be grounded.
· The motor cables may not be longer than 50m when shielded or 100m when non-shielded
· The pulse frequency (P076) may not exceed max. 4kHz
1.3.3 Installation after a Period of Storage
It is necessary to reform the capacitors in the inverter if the unit has been stored for a prolonged period:
·Period of storage 1 year old or less:
No reforming is required.
·1 - 2 years old:
Apply power to the inverter one hour before giving the run command (preparation time 1 hour).
·2 - 3 years old:
Use a variable AC supply. Apply 25% of input voltage for 30 minutes. Increase volts to 50% for a further
30 minutes. Increase volts to 75% for further 30 minutes. Increase volts to 100% for a further 30 minutes.
Now ready for run signal (preparation time 2 hours).
·3 years and over:
As with 2 - 3 years, but the steps should be 2 hours (preparation time 8 hours).
1.3.4 Operation with Long Cables
Motor cable lengths vary depending on type of cable, power rating and voltage rating - and in some cases can be as long as 200m
without the need for additional chokes. Refer to DA64 catalogue for further details.
In any case, all inverters will operate at full specification with cable lengths up to 25m for screened cable or 50m for unscreened
cables.
To guarantee safe operation of the equipment it must be installed and commissioned properly by qualified personnel i
compliance with the warnings laid down in these operating instructions.
Take particular note of general and regional installation safety regulations regarding work on dangerous voltage installation
(e.g. VDE), as well as the relevant regulations regarding the correct use of tools and personal protective gear.
The mains input and motor terminals carry dangerous voltages even if the inverter is not operating. Use insulate
screwdrivers on these terminal blocks.
MICROMASTER Vector inverters must be secured to a suitable vertical surface by bolts, washers and nuts. Frame size A units need
two bolts or can be DIN rail mounted. Frame size B and C units require four bolts.

DIP switches select between voltage (V) and current (
I) analogue inputs. They also select between either a voltage or current PID
feedback signal (see Figure 4.1.2: DIP Selector Switches). These switches can only be accessed when:
· for Frame size 4, 5 and 6 the front cover is removed (see Figure 3.2.1).
· for Frame size 7 the lower front cover is removed (see Figure 3.2.1).
3.2.3 Motor Overload Protection
When operated below rated speed, the cooling effect of fans fitted to the motor shaft is reduced. so that most motors require de-rating
for continuous operation at low frequencies. For protection measures using a PTC see section 2.2.5.
The digital frequency setpoint has been set at 5.00 Hz in the factory. It is not necessary to enter a frequenc
setpoint via the D button or parameter P005 in order to test that the motor turns following a RUN command.
ll settings must be entered by qualified personnel, paying particular attention to the safety precautions an
warnings.
The parameter settings required can be entered using the three parameterisation buttons (P, D and Ñ) on the front panel of the
inverter. The parameter numbers and values are indicated on the four digit LED display.

4.1.2 DIP Selector Switches
The five DIP selector switches have to be set in agreement with P023 or P323 according to the operation of the inverter. Figure 4.1.2
below, shows the settings of the switches for the different modes of operation.
Refer to section 6 for a full description of each parameter.
4.2.1 General
(1)The inverter does not have a main power switch and is therefore 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 via terminal 5 (rotate right- default)
or terminal 6 (rotate left- default) - see parameters P051 to P055 and P356.
(2)If output frequency (P001 = 0) is selected as the display, the corresponding setpoint is flashed on the display approximately
every 1.5 seconds while the inverter is stopped.
(3) The inverter is programmed at the factory for standard applications on Siemens standard motors. When using other motors it
is necessary to enter the specifications from the motor's rating plate into parameters P080 to P085 (see Figure 4.2.1). Note:
Access to these parameters is not possible unless P009 = 002 or 003.
(4) A separately-driven fan and/or a temperature sensor must be provided in the motor to protect it if the drive is operated
continuously below approx. 15 Hz drive inverter frequency
Figure 4.2.1: Typical Motor Rating Plate Example
Note:Ensure that the inverter is configured correctly to the motor, i.e. in the above example delta terminal connection is for 220 V.

4.2.2 Initial Testing
1. Check that all cables have been connected correctly (see section 2 or 3 ) and that all relevant product and plant/location safety
precautions have been complied with.
2. Apply mains power to the inverter.
3. Ensure that it is safe to start the motor. Press the RUN button on the inverter. The display will change to 5.0 and the motor shaft will
begin to turn. It will take 1 second for the inverter to ramp-up to 5 Hz.
4. Check that the motor rotates in the direction required. Press the FORWARD / REVERSE button if necessary.
5. Press the Stop button. The display will change to 0.0 and the motor will slow down, achieving a complete stop after 1 second.
The basic method of setting up the inverter for use is described below. This method uses a digital frequency setpoint and requires only
the minimum number of parameters to be changed from their default settings. It assumes that a standard Siemens four-pole motor is
connected to the inverter (see section 4.2.1 if another motor type is being used).
Step/ActionButtonDisplay
1. Apply mains power to the inverter.
The display will alternate between the actual frequency (0.0 Hz) and the requested
frequency setpoint (5.0 Hz default).
2. Press the parameterisation button.
P
3. Press the D button until parameter P005 is displayed.
4. Press P to display the present frequency setpoint (5 Hz is the factory default setting).
P
5. Press the D button to set the desired frequency setpoint
(e.g. 35 Hz).
6. Press P to lock the setting into memory.
7. Press the Ñ button to return to P000.
8. Press P to exit the parameterisation procedure.
The display will alternate between the present output frequency and the frequency
setpoint.
9. Start the inverter by pressing the RUN button.
The motor shaft will start to turn and the display will show that the inverter is ramping up
to the setpoint of 35 Hz.
Note
The setpoint will be achieved after 7 seconds (default ramp-up time, defined by P002 is
10s to reach 50 Hz, the default maximum motor frequency, P013).
If required, the motor’s speed (i.e. frequency) can be varied directly by using the D Ñ
buttons. (Set P011 to 001 to enable the new frequency setting to be retained in memory
during periods when the inverter is not running.)
10. Switch the inverter off by pressing the STOP button.(see section 5.4)
The motor will slow down and come to a controlled stop.
Note
Full stop will be achieved after 7 seconds (default ramp-down time, defined by P003 is 10 s
from 50 Hz, the default value P013).
For a basic start-up configuration using digital control, proceed as follows:
(1)Connect control terminal 9 to terminal 5 via a simple on/off switch. This sets up the inverter for clockwise rotation of the motor
shaft (default).
(2)Secure all covers to the unit and then 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 P080 to P085 in accordance with the rating plate on the motor (see Figure 4.2.1).
(7) Set the external on/off switch to ON. The inverter will now drive the motor at the frequency set by P005.
5.2 Analogue Control
For a basic start-up configuration using analogue voltage control, proceed as follows:
(1)Connect control terminal 9 to terminal 5 via a simple on/off switch. This sets up the motor for clockwise rotation (default).
(2)Connect a 4.7 kW potentiometer to the control terminals as shown in Figures 2.2.4 and 2.2.6 (MMV) (Figures 3.2.2 and 3.2.4
(MDV)) or connect pin 2 (0V) to pin 4 and a 0 - 10 V signal between pin 2 (0V) and pin 3 (AIN+).
(3)Set the Analogue Input 1 Configuration DIP selector switches 1, 2 and 3 for voltage (V) input. (see Figure 3.2.2-3.2.4, Section
4.1.2)
(4)Secure all covers to the unit and then apply mains power to the inverter. Set parameter P009 to 002 or 003 to enable all
parameters to be adjusted.
(5)Set parameter P006 to 001 to specify analogue setpoint.
(6)Set parameter P007 to 000 to specify digital input and disable the front panel controls.
(7)Set parameters P021 and P022 to specify the minimum and maximum output frequency settings.
(8) Set parameters P080 to P085 in accordance with the rating plate on the motor (see Figure 4.2.1).
(9) Set the external on/off switch to ON. Turn the potentiometer (or adjust the analogue input control voltage) until the desired
frequency is displayed on the inverter.
5.3 Motor Control Modes
The MICROMASTER Vector and MIDIMASTER Vector inverters have four different modes of operation which control the relationship
between the voltage supplied by the inverter and the speed of the motor. The motor control mode of operation is selected at P077:
· Linear voltage/frequency Operation.
· Flux Current Control (FCC) which is used to maintain full flux conditions in the motor.
· Quadratic voltage/frequency relationship which is used for pumps and fans.
· Sensorless Vector. The inverter calculates the changes required in output voltage to maintain the desired motor speed.
These modes are described in more detail below.
5.3.1 Linear Voltage to Frequency (V/f) (P077 = 0 or 2)
This mode is used for synchronous motors or motors connected in parallel. Each motor should be installed with a thermal overload
relay if two or more motors are driven simultaneously by the inverter.
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, an automatic Stator Resistance calibration should be performed by
setting P088 =1. Continuous Boost (P078) and Starting Boost (P079) are dependent on the value of Stator Resistance - too high a
value may cause overcurrent trips or motor overheating.
5.3.2 Flux Current Control (FCC) Operation (P077 = 1)
Flux Current Control operates by monitoring and maintaining the motor flux current continuously. This ensures that the best
performance and efficiency are obtained. FCC is not as complex as SVC, and therefore is easier to set up and operate.
Note: This mode can result in reduced power consumption.
5.3.3 Sensorless Vector Control (SVC) Operation (P077 = 3)
When SVC operating mode is selected (P077=3), the inverter uses an internal mathematical model of the motor, together with accurate
current sensing, to calculate the position and speed of the rotor. It is therefore able to optimise the applied voltage and frequency to the
motor to give improved performance.
Although there is no position or speed feedback from the motor, the control system is a closed loop system because it compares the
internal motor model performance with the desired performance. The system must therefore be carefully set up and stabilised for best
performance.
Setting up SVC Operation
1. Set the correct Motor parameter settings in Parameters P080 to P085.
3. Ensure that the motor is cold and apply a run command. The display will show CAL to indicate that it is measuring the motor stator
resistance. After a few seconds the motor will run. Calibration only occurs the first time that a run command is given following P077
being set to 3. It can be forced by changing P077 from SVC operation and back again, or by selecting P088 =1 (Stator Resistance
Calibration). Interrupting the calibration process by disconnecting the power or removing the run command may give erroneous
results and calibration should be repeated. If motor parameters are changed recalibration is also recommended.
4. Like any control system, SVC must be stabilised by setting the Gain (P386) and Integral (P387) terms. Actual values and setting
up is determined by testing, but the following procedure is suggested:
Whilst the inverter is operating under typical conditions, increase the value of P386, the loop gain, until the first
signs of speed instability occur. The setting should then be reduced slightly (approx. 10%) until stability is restored.
As a guide, the optimum setting required will be proportional to the load inertia.
For example: P386 = Load inertia + motor shaft inertia
motor shaft inertia
P387, the integral term, may now be adjusted. Again, whilst operating the inverter under typical conditions,
increment this parameter until the first signs of speed instability occur. The setting should then be reduced slightly
(approx. 30%) until stability is restored.
If fault code F016 occurs, this indicates that SVC is unstable and further adjustment or recalibration is needed. F001, DC link
overvoltage can also be caused by instability in SVC operating mode.
For further information concerning SVC operation refer to Application Note “Sensorless Vector Control”, which may be obtained from
http://www.siemens.com/micromaster or a Siemens Sales Office.
Note: This mode gives the best flux control and higher torque.
5.4 Stopping the Motor
Stopping can be achieved in several ways:
·Cancelling the ON command on the terminals or pressing the OFF button (O) on the front panel causes the inverter to Ramp-down
at the selected Ramp-down rate (see P003).
· OFF2 - operation causes the motor to coast to a standstill (parameters P051 to P055 or P356 set to 4).
· OFF3 - operation causes rapid braking (parameters P051 to P055 or P356 set to 5).
· DC injection braking up to 250% produces more effective braking to provide a quicker stop after cancellation of the ON command
(see P073).
· Resistive braking for MMV (see parameter P075).
· Compound braking (see P066)
5.5 If the Motor Does Not Start Up
If the display shows a fault code, refer to section 7.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 P080 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 1 and then pressing P.
5.6 Local and Remote Control
The inverter can be controlled either locally (default), or remotely via a USS data line connected to the internal interface terminals (24
and 25) or to the RS485 D-type connector on the front panel. (Refer to parameter P910 in section 6 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.
For remote control, the serial interface is designed as a 2-wire connection for bi-directional data transmission. Refer to parameter P910
in section 6 for the available remote control options.
Note:Only one RS485 connection is allowed. Use either the front panel D-type interface [e.g. to connect an Clear Text
Display(OPM2)] or terminals 24 and 25, but not both.
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 P055 and P356 (see section 6).
Several inverters can be connected to an external control unit at the same time. The inverters can be addressed individually.Note:If the inverter has been set up to operate via the serial link but does not run when an ON command is received, try reversing
the connections to terminals 24 and 25 .

5.7 Closed Loop Control
5.7.1 General Description
The MICROMASTER provides a PID control function for closed loop control (see Figure 5.7.1). PID control is ideal 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. When closed loop process control is enabled
(P201 = 001), all setpoints are calibrated between zero and 100%, i.e. a setpoint of 50.0 = 50%.

MICROMASTER Closed loop PID control - Block Diagram
Make sure that the DIP selector switches 4 and 5 are correctly set (see Figure 4.1.2) and in agreement with P323 for unipolar voltage or
current feedback signal inputs. Connect the external feedback transducer between control terminals 10 and 11 (analogue input 2). This
analogue input accepts a 0/2 - 10 V or a 0/4 - 20 mA input signal (determined by the setting of the DIP selector switches 4 and 5 and
P323), has 10-bit resolution and permits a differential (floating) input. 15 V dc power for the feedback transducer can be supplied from
terminal 9 on the control block.
Closed loop process control cannot be used unless P201 is first set to 001. Most of the parameters associated with closed loop process
control are shown in Figure 5.7.1. Other parameters which are also associated with closed loop process control are as follows:
P010 (only if P001 = 1, 4, 5, 7 or 9)
P061 (value = 012 or 013)
P220
Descriptions of all closed loop process control parameters are provided in section 6. For detailed information about PID operation, refer
to the application note “Closed Loop Control”, which may be obtained from
http://www.siemens.com/micromaster or a Siemens sales office.
Parameters can be changed and set using the keypad on the front panel (see Figure 4.1.1) 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 four digit LED display.
Note:If the D or Ñ button is pressed momentarily, the values change step by step. If the button is pressed for a longer time, the
values scroll through rapidly.
Access to parameters is determined by the value set in P009. Make sure that the key parameters necessary for the 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.
Increased Parameter Resolution
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 D or Ñ to change the value (all values between .00 and .99 are valid) and then press P twice to return to the
parameter display.
Resetting to Factory Defaults
If parameters are changed accidentally, all parameters can be reset to their default values by setting parameter P944 to 1 and then
pressing P.
In the event of a failure, the relevant fault code (Fnnn) is displayed (seesection 7) or the display flashes in the event of a warning (see P931) or If
output frequency has been selected (P001 = 0) and the inverter is in stand-by
mode, the display alternates between the setpoint frequency and the actual
output frequency which is zero Hz.
Display selection:
0 = Output frequency (Hz)
1 = Frequency setpoint (i.e. speed at which inverter is set to run)
(Hz)
2 = Motor current (A)
3 = DC-link voltage (V)
4 = Motor torque (% nominal)
5 = Motor speed (rpm)
6 = USS serial bus status (see section 9.2)
7 = PID Feedback signal (%)
8 = Output voltage (V)
9 = Instantaneous rotor / shaft frequency (Hz).Note: Applicable only for
Sensorless Vector control mode.
Notes: 1. The display can be scaled via P010.
2. When the inverter is operating in Sensorless Vector Control
mode (P077 = 3) the display shows actual rotor / shaft speed in
Hz. When the inverter is operating in V/f or FCC modes (P077 = 0,
1 or 2) the display shows inverter output frequency in Hz.
WARNING: In Sensorless Vector Control mode (P077 = 3) the display
shows 50Hz when a 4-pole motor is rotating at 1500rpm
which may be slightly higher than the nominal speed shown
on the motor rating plate.
This is the time taken for the motor to accelerate from standstill to the maximum
frequency as set in P013. Setting the Ramp-up time too short can cause the
inverter to trip (fault code F002 - overcurrent).

This is the time taken for the motor to decelerate from maximum frequency (P013)

This is also the period for which DC injection braking is applied when P073 is
selected.
Used to smooth the acceleration/deceleration of the motor (useful in
applications where it is important to avoid ‘jerking’, e.g. conveyor systems,

Sets the frequency that the inverter will run at when operated in digital mode.
Only effective if P006 = 0 or 3.
Selects the mode of control of the frequency setpoint for the inverter.
0 = Digital motorised potentiometer. The inverter runs at the frequency set in
P005 and can be controlled with the D and Ñ pushbuttons (motorised
potenti ometer). Alternatively, if P007 is set to zero, the frequency may be
increased or decreased by setting any two of the digital inputs (P051 to
P055 or P356) to values of 11 and 12.
1 = Analogue. Control via analogue input signal.
2 = Fixed frequency. Fixed frequency is only selected if the value of at
least one of the digital inputs (P051 to P055 or P356) = 6 17 or
18.
3 = Digital setpoint addition. Requested frequency = digital frequency
(P005) + fixed frequencies (P041 to P044, P046 to P049) as
selected.
Notes:(1) If P006 = 1 and the inverter is set up for operation via the serial link,
the analogue inputs remain active.
(2) Motorised potentiometer setpoints via digital inputs are stored
upon power-down when P011 = 1.
0 = RUN, JOG and REVERSE are disabled. Control is via digital inputs
(see parameters P051 - P055 and P356). D and Ñ may still be used to
control frequency provided that P124 = 1 and a digital input has not
been selected to perform this function.
1 = Front panel buttons can be selectively enabled or disabled depending
on the setting of parameters P121 - P124.
Note: The digital inputs for RUN, JOG and increase/decreasefrequency
are disabled.
Determines which parameters can be adjusted:
0 = Only parameters from P001 to P009 can be read/set.
1 = Parameters from P001 to P009 can be set and all other
parameters can only be read.
2 = All parameters can be read/set but P009 automatically resets to 0
when power is removed.
3 = All parameters can be read/set.
Scale factor for display when P001 = 0, 1, 4, 5, 7 or 9.
Four digit resolution.
0 = Disabled
1 = Enabled after switch-off. i.e. the setpoint alterations made with the D / Ñ
buttons are stored even when power has been removed from the
inverter.
Sets the minimum motor frequency (must be less than the value of P013).
Sets the maximum motor frequency.
CAUTION: To maintain stable operation when in sensorless vector control
mode (P077=3), the maximum motor frequency (P013), should not exceed 3x
nominal rating plate motor frequency (P081).
A skip frequency can be set with this parameter to avoid the effects of
resonance of the inverter. Frequencies within +/- (the value of P019) of this
setting are suppressed. Stationary operation is not possible within this
suppressed frequency range - the range is just passed through. Setting
P014=0 disables this function.
Setting this parameter to ‘1’ enables the inverter to restart automatically after
a mains break or ‘brownout’, provided the external run/stop switch, connected
to a digital input, is still closed, P007 = 0 and P910 = 0, 2 or 4.
0 = Disabled
1 = Automatic restart
Allows the inverter to start onto a spinning motor.
Under normal circumstances the inverter runs the motor 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 flying restart, the inverter ‘homes in’ on the motor's speed and runs it up from that
speed to the setpoint. (Note: If the motor has stopped or is rotating slowly, some
‘rocking’ may occur as the inverter senses the direction of rotation prior to
restarting.)
0 = Normal restart
1 = Flying restart after power up, fault or OFF2 ( if P018 = 1).
2 = Flying restart every time (useful in circumstances where the motor
can be driven by the load).
3 = As P016 = 1 except that the inverter will only attempt to restart the
motor in the direction of the requested setpoint. The motor is
prevented from ‘rocking’ backwards and forwards during the initial
frequency scan.
4 = As P016 = 2 except that the inverter will only attempt to restart the
motor in the direction of the requested setpoint. The motor is
prevented from ‘rocking’ backwards and forwards during the initial
frequency scan.
Note:For MIDIMASTER Vector units, it is recommended that if P016 > 0
then P018 should be set to ‘1’. This will ensure correct re-starting
if the inverter fails to re-synchronise on the initial attempt.
IMPORTANT:
When P016 > 0, care must be taken to set up the motor
nameplate data (parameters P080 toP085) and to perform an
auto stator resistance calibration (P088=1) on a cold motor.
Recommended maximum operating frequency should be less
than 120 Hz.
1 = Continuous smoothing (as defined by P004).

1 = The inverter will attempt to restart up to 5 times after a fault. If the
fault is not cleared after the 5th attempt, the inverter will remain in
the fault state. The display flashes during this condition.
WARNING:
While waiting to re-start, the display will flash. This means
that a start is pending and may happen at any time. Fault
codes can be observed in P140 and P930.
Frequencies set by P014, P027, P028 and P029 that are within +/- the value
of P019 of all skip frequencies are suppressed.
Frequency corresponding to the lowest analogue input value, i.e.
0 V/0 mA or 2 V/4 mA, determined by P023 and the settings of the DIP
selector switches 1, 2 and 3 (see Figure 4.1.2). This can be set to a higher
value than P022 to give an inverse relationship between analogue input and
frequency output (see diagram in P022).
Frequency corresponding to the highest analogue input value, i.e.
10 V or 20 mA, determined by P023 and the setting of the DIP selector
switches 1, 2 and 3 (see Figure 4.1.2) This can be set to a lower value than
P021 to give an inverse relationship between analogue input and frequency
output.

Note:Setting P023 = 2 will not work unless the inverter is under full local
control (i.e. P910 = 0 or 4) and V ³ 1 V or 2mA.
WARNING: The inverter will automatically start when voltage goes
above 1V. This equally applies to both analogue and digital

Description / Notes
This provides a method of scaling the analogue output 2 in accordance with
the table shown in P025.
See P014.

See P014.
Jogging is used to advance the motor by small amounts. It is controlled via
the JOG button or with a non-latching switch on one of the digital inputs (P051
to P055 and P356).
If jog right is enabled for one if these digital inputs (e.g. P051-55 or P356 =7) or if the
Job Button is pressed this parameter controls the frequency at which the inverter will
run when the switch is closed. Unlike other setpoints, it can be set lower than the
minimum frequency.
If jog left is enabled (e.g. P051-55 or P356 = 8), this parameter controls the frequency
at which the inverter will run when the switch is closed. Unlike other setpoints, it can be
set lower than the minimum frequency.
This is the time taken to accelerate from 0 Hz to maximum frequency
(P013) for jog functions. It is not the time taken to accelerate from 0 Hz to
the jog frequency.
If one of the digital inputs is programmed to select jog ramp times, the
corresponding digital input can be used to select the ramp time set by this
parameter instead of the normal Ramp-up time set by P002.
This is the time taken to decelerate from maximum frequency (P013) to 0 Hz
for jog functions. It is not the time taken to decelerate from the jog frequency
to 0 Hz.
If one of the digital inputs is programmed to select jog ramp times, the
corresponding digital input can be used to select the ramp time set by this
parameter, instead of the normal Ramp-down time set by P003.
0 - Disabled
1 - Under normal operation the ramp-down time is defined as the time taken
to ramp-down from the value set in P013 to 0. Setting P040 to 1 will
automatically re-scale the ramp down time so that the motor will always stop
in the same position regardless of operating frequency.

e.g. P003 = 1s, P013 = 50Hz, P012 = 0Hz.
If the motor is running at 50Hz and a stop command applied, the motor will
stop in 1second. If the motor is running at 25Hz, the motor will stop in 2
seconds and if the motor is running at 5Hz, the motor will stop in 10 seconds.
In each case, the motor will stop at the same position.

Inverter switches off (see parameter P930 and P140 to P143 and section 7).
Only effective if the relay output is set to control an external brake
(P061 or P062 = 4). In this case when the inverter is switched on, it will run at
the minimum frequency for the time set by this parameter before releasing the
brake control relay and ramping up (see illustration in P064).
As P063, only effective if the relay output is set to control an external brake.
This defines the period for which the inverter continues to run at the minimum
frequency after ramping down and while the external brake is applied.

Notes:(1)Settings for P063 and P064 should be slightly longer than the
actual time taken for the external brake to apply and release
respectively
(2)Setting P063 or P064 to too high a value, especially with
P012 set to a high value, can cause an overcurrent warning or
trip as the inverter attempts to turn a locked motor shaft.
This parameter is used when P061 or P062 = 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 to 250 = Defines the level of DC superimposed on the AC waveform,
expressed as a percentage of P083. Generally, increasing this value
improves braking performance, however, with 400V inverters, a high
value in this parameter could cause F001 trips.
Note: Compound braking does not operate in Sensorless Vector control mode
(P077=3).
0 - Ramp extension disabled.
1 - Ramp extension enabled. Ramp time is increased during current limit,
overvoltage limit and slip limit to prevent tripping.

Note: Ramp extension does not occur when in vector control (P077=3).
WARNING:Standard braking resistors for the MICROMASTER Vector
are designed for the 5% duty cycle only. Do not select
higher duty cycles unless suitably rated resistors are
being used to handle the increased power dissipation.
The maixmum on time for values 0 to 3 is limited
according to the brake resistor thermal capacity. Limit is
12 seconds for 5%, increasing to 25 seconds for 50%.
The inverter can estimate the amount of slip in an asynchronous motor at
varying loads and increase its output frequency to compensate. This parameter
‘fine tunes’ the compensation for different motors in the range 0 - 200% of the
calculated slip.
Note: This feature is not active and is not necessary when inSensorless
Vector Control (P077=3).
WARNING:This parameter must be set to zero when using
synchronous motors or motors that are connected in
parallel or over-compensation can cause instability.
0 - 499 - This limits the slip of the motor to prevent ‘pull-out’ (stalling), which
can occur if slip is allowed to increase indefinitely. When the slip
limit is reached, the inverter reduces frequency to keep the level of
slip below this limit.
500 - Disables slip limit warning
This rapidly stops the motor by applying a DC braking current and holds the
shaft stationary until the end of the braking period. Additional heat is generated
within the motor. Braking is effective for the period of time set by P003.
The DC brake can be activated using DIN1 to DIN6 (see P051 to P055 andP356).
WARNING:Frequent use of long periods of dc injection braking can
cause the motor to overheat.
If DC injection braking is enabled via a digital input then
DC current is applied for as long as the digital input is
high. This causes heating of the motor.
Selects the most appropriate curve for the motor derating at low frequencies
due to the reduced cooling effect of the shaft mounted cooling fan.

[0 or 4]
Description / Notes
Sets the pulse frequency (from 2 to 16 kHz) and the PWM mode. If 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
Even numbers = normal modulation technique.
Odd numbers = lower loss modulation technique used when operating mainly
at speeds above 5 Hz.
As a result of the higher losses at higher pulse frequencies than those set in
the factory, the maximum continuous output current is reduced as a function of
the pulse frequency. If values 4, 5, 6 or 7 are selected for P076, then the drive
inverters are not de-rated. The power de-rating is also valid for MMVXXX/3F
with integrated filter. For MIDIMASTER Vector drive converters with 230V from
30kW upwards, 400V from 45kW upwards, and 575V from 22kW upwards,
P076 can only be set to values 4, 5, 6 or 7 (4kHz or 2kHz). The pulse
frequency is automatically reduced if the internal drive inverter monitoring
functions determine an excessive heatsink temperature. The frequency is
automatically increased again when the temperature has returned to a normal
value.
Controls the relationship between the speed of the motor and the voltage
supplied by the inverter. One of four modes can be selected:
0 = V/f curve
1 = FCC control
2 = Quadratic V/f
3 = Vector Control
Note: When Sensorless Vector Control is selected (P077 = 3), P088 will
automatically be set to 1, so that on first run-up, the inverter will
measure the stator resistance of the motor and calculate motor
constants from the rating plate data in P080 to P085.
For many applications it is necessary to increase low frequency torque. This
parameter sets the start-up current at 0 Hz to adjust the available torque for low
frequency operation. 100% setting will produce rated motor current (P083) at
low frequencies.
WARNING:If P078 is set too high, overheating of the motor and/or
For drives which require a high initial starting torque, it is possible to set an
additional current (added to the setting in P078) during ramp duration (P002).
This is only effective during initial start up and until the frequency setpoint is
reached.

Notes:
1 These parameters P080 to P085 must be set for the particular motor used.

2 It will be necessary to perform an automatic calibration (P088 = 1) if P080 to
P085 are changed from their factory default settings.

Defines the motor overload current as a % of the Nominal motor current (P083)
allowed for up to one minute.
With this parameter and P186, the motor current can be limited and
overheating of the motor prevented. If the value set in P083 is exceeded for
one minute, (or longer if the overload is small) , the output frequency is reduced
until the current falls to that set in P083. The inverter display flashes as a
warning indication but the inverter does not trip. The inverter can be made to
trip using P074.
Note: The maximum value that P086 can be set to is automatically limited by
the rating of the inverter. Further, the power can be automatically
reduced for pulse frequencies which differ from the factory setting
(refer to P076)
0 = Disabled
1 = External PTC enabled
Note:If motor thermal protection is required, then an external PTC must
be used and P087 = 1. If P087 = 1 and the PTC input goes high
then the inverter will trip (fault code F004 displayed).
The motor stator resistance is used in the inverter's internal current monitoring
calculations. When P088 is set to ‘1’ and the RUN button is pressed, the
inverter performs an automatic measurement of motor stator resistance; stores
it in P089 and then resets P088 to ‘0’.
If the measured resistance is too high for the size of inverter (e.g. motor not
connected or unusually small motor connected), the inverter will trip (fault code
F188) and will leave P088 set to ‘1’. If this happens, set P089 manually and
then set P088 to ‘0’.
Can be used instead of P088 to set the motor stator resistance manually. The
value entered should be the resistance measured across any two motor
phases.
WARNING:The measurement should be made at the inverter
terminals with power off and cold motor.
Note:If the value of P089 is too high then an overcurrent trip(F002) may
occur.
Up to 31 inverters can be connected via the serial link and controlled by a
computer or PLC using the USS serial bus protocol. This parameter sets a
unique address for the inverter.
Sets the baud rate of the RS485 serial interface (USS protocol):
Note:Some RS232 to RS485 converters are not capable of baud rates
higher than 4800.
This is the maximum permissible period between two incoming data telegrams.
This feature is used to turn off the inverter in the event of a communications
failure.
Timing starts after a valid data telegram has been received and if a further data
telegram is not received within the specified time period, the inverter will trip
and display fault code F008.
Setting the value to zero switches off the control.
Setpoints are transmitted to the inverter via the serial link as percentages. The
value entered in this parameter represents 100%
(HSW = 4000H).

Description / Notes
Stores the peak current seen by the motor. Can be reset using D and
Ñbuttons.
Read only. The last recorded fault code (see section 7) is stored in this
parameter. The stored value can be cleared by using the D and Ñ buttons. Or
by resetting to factory defaults (P944)
This is a copy of the code stored in P930.
Read only. This parameter stores the last recorded fault code prior to that
stored in P140/P930.
Read only. This parameter stores the last recorded fault code prior to that
stored in P141.
Read only. This parameter stores the last recorded fault code prior to that
stored in P142.
This parameter defines the instantaneous motor current limit as a % of the
nominal motor current (P083). If the output current reaches this limit for three
seconds, the inverter automatically reduces the current to the limit set in P086.
Note: * The maximum value that can be set for P186 is automatically limited by
the rating of the inverter.
Torque limit operation is available, from 5Hz to 50Hz, when using Vector
Control mode (P077=3). The motor torque produced is a function of motor
current. If P186 and P086 are equal, the current limit function can effectively be
used as a torque limit.
0 = Normal operation (closed loop process control disabled).
1 = Closed loop process control using analogue input 2 as feedback.

0 = Normal operation.
1 = Switch off inverter output at or below minimum frequency.
Note: Active in all modes.
Frequency corresponding to the lowest analogue input value, i.e.
0 V/0 mA or 2 V/4 mA, determined by P323 and the settings of the DIP selector
switches 4 and 5 (see Section 4.1.2). This can be set to a higher value than
P322 to give an inverse relationship between analogue input and frequency
output (see diagram in P322).
Frequency corresponding to the highest analogue input value, i.e.
10 V or 20 mA, determined by P323 and the setting of the DIP selector
switches 4 and 5 (see Section 4.1.2).. This can be set to a lower value than
P321 to give an inverse relationship between analogue input and frequency
output.
f

Sets analogue input type for analogue input 2, in conjunction with the settings
of the DIP selector switches 4 and 5 (see, Section 4.1.2) :
0 = 0 V to 10 V/ 0 to 20 mA Unipolar input
1 = 2 V to 10 V/ 4 to 20 mA Unipolar input
2 = 2 V to 10 V/ 4 to 20 mA Unipolar input with controlled start /
stop when using analogue input control.
Note: Setting P323 = 2 will not work unless the inverter is under full local
control (i.e. P910 = 0 or 4) and V ³ 1 V or 2mA.
WARNING: The inverter will automatically start when voltage goes above
1V or 2mA. This equally applies to both analogue and digital
control (i.e. P006 = 0 or 1)
Control function selection, DIN 6
See P051 - P055 for description.
To optimise the dynamic performance of the vector control this parameter
should be incremented whilst the inverter is operating under typical conditions
until the first signs of speed instability occur. The setting should then be
reduced slightly (approx. 10%) until stability is restored. In general, the
optimum setting required will be proportional to the load inertia. If this setting is
too low or too high, rapid load changes may result in DC link overvoltage trips
(F001) and/or unstable vector control.
See section 5.3.3 for further information .
Note: P386 = Load inertia + motor shaft inertia
motor shaft inertia
P386 must be optimised before adjusting P387. Whilst operating the inverter
under typical conditions, increment this parameter until the first signs of speed
instability occur. The setting should then be reduced slightly (approx. 30%) until
stability is restored.

Description / Notes
Allows direct access to the relay outputs and the analogue output via the serial
link (USS or PROFIBUS-DP with module):
0 = Normal operation
1 = Direct control of relay 1
2 = Direct control of relay 2
3 = Direct control of relay 1 and relay 2
4 = Direct control of analogue output 1 only
5 = Direct control of analogue output 1 and relay 1
6 = Direct control of analogue output 1 and relay 2
7 = Direct control of analogue output 1, relay 1 and relay 2
Read only. Displays the analogue input 1 voltage (approximate).
Allows direct control of the output current over the serial link if P720 = 4, 5, 6 or
7.
Read-only. Provides a HEX representation of a 6-digit binary number of which
the LSB = DIN1 and the MSB = DIN6 (1 = ON, 0 = OFF).
e.g. If P723 = B, this represents ‘001011’ - DIN1, DIN2 and DIN4
= ON, DIN3 , DIN5 and DIN6 = OFF.
Enables control of the output relays. Used in conjunction with P720, e.g. setting
P724 = 1 (relay 1 = ON) has no effect unless P720 = 1, 3, 5,or 7.
0 = Both relays OFF / de-energised
1 = Relay 1 ON / energised
2 = Relay 2 ON / energised
3 = Both relays ON / energised
Read only. Displays the analogue input 2 voltage (approximate) only when
analogue input 2 is active (P051 to P055 or P356 = 24 and the respective
digital input is high).
Allows direct control of the analogue output 2 current over the serial link if P720
= 4, 5, 6 or 7.
Specific to PROFIBUS-DP. See PROFIBUS Handbook for further details.
Access only possible with P099 = 1
CANbus Handbook for further details.
Access only possible with P099 = 1 or 2
Sets the inverter for local control or USS control over the serial link:
0 = Local control
1 = USS control (and setting of parameter values)
2 = Local control (but USS control of frequency)
3 = USS control (but local control of frequency)
4 = Local control (but USS read and write access to
parameters and facility to reset trips)
Note:When operating the inverter via USS control (P910 = 1
or 2 ), the analogue input remains active when P006 = 1
and is added to the setpoint.
Contains the software version number and
cannot be changed.
You can use this parameter to allocate a unique reference number to the
inverter. It has no operational effect.
See Parameter 140
Read only. The last recorded warning is stored in this parameter until power is
removed from the inverter. This can be cleared by using the D and Ñ buttons.
Set to ‘1’ and then press P to reset all parameters except P101 to the factory
default settings. Previously set parameters will be overwritten including the
motor parameters P080 - P085 (See section 4.2)
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.
IMPORTANT: When using the serial link to update the parameter set
held in EEPROM, care must be taken not to exceed the maximum number
of write cycles to this 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 fault, the inverter switches off and a fault code appears on the display. The last fault that occurred is stored in
parameter P140, the preceding faults in P141 - P143.. e.g. ‘0004’ indicates that the last fault was F004

Comment:
MICROMASTER Vector and MIDIMASTER Vector are designed for use worldwide and therefore for wide line supply voltage ranges (1/3-ph. 208 - 240
V AC ±10%; 3-ph. 380 - 500 V AC ±10%; 3-ph. 525 - 575V AC ±15%)
For the voltage data, it should be noted that:
the operating range of the drive inverter lies between the two specified voltage values - e.g. 208 - 240V,
-
the ±10% does not represent an operating range but only the range which is provided to absorb brief voltage fluctuations.
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:MMV150 (6SE3216-8BB40)
Settings:P009 = 2 (all parameters can be altered)
P080 - 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
V
220
(voltage/frequency curve is linear up to 50 Hz).
Motor potentiometer setpoint in addition to
analogue setpoint .
Use of analogue setpoint at maximum 10 Hz.

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 Vector and MIDIMASTER Vector 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 1.2.
