Figure 2-12 PTC Connections
PTC Resistor connects between
terminals 4 (+24 V) and 3 (DIN 3).
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
Make sure that any control equipment connected to the inverter (such as a
PLC) is connected to the same ground or star point as the inverter via a short,
thick link.
Flat conductors are preferred as they have lower impedance at higher
frequencies.
Separate the control cables from the power connections as much as
possible, using separate trunking, if necessary at 90
Ensure that contactors 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.
Screened motor cables should be used when the motor is mounted separately
from the inverter.
Maximum motor cable length is 5 meters (16.40 feet).
WARNING
Safety regulations must not be compromised when installing inverters!

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
continue to function 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 may 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.

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 460 V
when protected by an H or K Class fuse (see Table 7-6).
CAUTION
Only qualified personnel may enter settings in the control panels. Particular
attention must be paid to safety precautions and warnings at all times.
The COMBIMASTER 411 & MICROMASTER 411 is supplied with default
parameter settings that cover the following requirements:

the control potentiometer or by using a potentiometer via the inverter’s
analogue input.
Ramp-up time / Ramp-down time = 10 s.
If more complex application settings are required, please refer to the parameter
listing.
To change parameters you will need one of the optional modules "Basic Operator
Panel" (BOP), the "Advanced Operator Panel" (AOP) or the set-up software (on the
Docu-CD supplied).
For basic operation no additional equipment is required.
However, for more complex operation either the Basic Operator Panel (BOP),
Advanced Operator Panel (AOP) or the set-up software contained on the Docu-CD
is required.
The COMBIMASTER 411/MICROMASTER 411 can additionally be integrated into
automation systems via the PROFIBUS module (option) or USS interface.
When delivered the inverter has a frequency setpoint range of between 0 Hz and
50 Hz.
WARNING
The inverter does not have a power supply switch and is therefore live when the
power supply is connected.
Inverter ramp times are set using a series of 5 jumpers (fit jumper to enable
function). Each jumper must be set as shown in Table 3-1.
The jumpers overwrite the default settings or the ramp times specified using
BOP/AOP/IBN software.
The inverter recognizes when jumper values have been set when power is reapplied.
CAUTION
Jumpers have priority in setting ramp times. When the jumpers are removed the
ramp times are not changed. It is then possible to change ramp times via the
parameters (using the BOP).
Ramp times apply to Ramp Up and Ramp Down. Jumper locations are as shown in
Figure 3-3.
Figure 3-3 Ramp Time Jumpers
Using up to 5 jumpers allows ramp times to be set between 1 - 240 s. Also see

3.3.4.1 Commissioning with the Basic Operator Panel (BOP)
The Basic Operator Panel (BOP), which is available as an
optional accessory, provides the user with access to the
inverter parameters and enables you to customize the
settings of your COMBIMASTER 411 & MICROMASTER
411. The BOP is mounted in an Operator Panel Mounting
Kit and connected to the COMBIMASTER 411 &
MICROMASTER 411 via the serial interface (see Figure
3-9). The BOP can be used to configure several
COMBIMASTER 411 & MICROMASTER 411 Inverters.
The BOP features a five-digit, seven-segment display for
showing parameter numbers and values, alarm and fault messages and setpoints
and actual values. Parameter sets cannot be saved via the BOP.
Control functions for the inverter (ON/OFF,
, , reverse) are not active in the
works settings. In order to specify this command via the BOP, P0700 = 1 must be
set.
If the BOP connection is removed during normal running the drives is stopped and
the motor coasts to standstill.

3.3.4.3 Quick commissioning (P0010=1)
Mechanical and electrical installation of the inverter must be completed before
running „Quick Commissioning“.
It is important that the parameter P0010 is used for commissioning and P0003 for
selecting the parameter level (level). Quick commissioning particularly uses
parameters concerning the motor data and the acceleration and deceleration times.
Quick commissioning is ended with P3900. If this parameter is set to 1, it makes
the required motor calculations and sets all parameters which are not part of the
quick commissioning to the default values.
NOTE
Parameter P0399 = 0 must be set before starting quick commissioning because it
is not possible to change the motor data in the works default setting. Once quick
commissioning has been completed, P0399 = 2 must be set.

NOTICE
1. The inverter does not have a main power switch and is live when the power
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 1 (ON/OFF1).
2. If a BOP or an AOP is fitted and the output frequency is selected to be
displayed (P0005 = 21) the corresponding setpoint is displayed approximately
every 1.0 seconds while the inverter is stopped.
3. The inverter is programmed at the factory for standard applications on
Siemens four-pole standard motors that have the same power rating as the
inverters. When using other motors it is necessary to enter the specifications
from the motor's rating plate. See Figure 3-7 for details on how to read motor
data.
4. Changing motor parameters is not possible unless P0010 = 1 and P004 = 0

4.4 Control Modes (P1300)
The various modes of operation of the MICROMASTER 411 control the relationship between the speed of the motor and the voltage supplied by the inverter. A
summary of the control modes available are listed below:
Linear V/f control P1300 = 0
Can be used for variable and constant torque applications, such as conveyors
and positive displacement pumps.
Linear V/f control with FCC (Flux Current Control) P1300 = 1
This control mode can be used to improve the efficiency and dynamic
response of the motor.
Quadratic V/f control P1300 = 2
This mode can be used for variable torque loads, such as fans and pumps.
Multi-point V/f control P1300 = 3
Multi-point V/f allows the user to define their own V/f Characteristics.
This characteristic uses two fixed coordinates and three pairs of variable
coordinates.
Fixed co-ordinates are: Boost as defined in P1310 at 0 Hz.
Nominal voltage P0304 at nominal frequency P0310
Variable co-ordinates may be obtained from the following three pairs of
coordinates
P1320 (frequency) -P1321 (voltage)
P1322 (frequency) -P1323 (voltage)
P1324 (frequency) -P1325 (voltage)
User programmable V/f characteristics are often used to provide correct torque
at correct frequency, which can be useful when using the Inverter with
synchronous motors. See Parameter List for further detail.
4.5 Faults and warnings
LED Fault Indication
Fault states and warnings are indicated by the LED within the control potentiometer

reduction and/or output frequency reduction (depending on parameterization in P0610)
Diagnose & Remedy
Check the following:
Load conditions and duty cycle must be appropriate
Fan must turn when inverter is running
Pulse frequency (P1800) must be set to default value
Ambient temperature could be higher than specified for the inverter

Possible Causes
CB (communication board) reports a configuration error.
Diagnose & Remedy
Check CB parameters
A0910 Vdc-max controller de-activated
Possible Causes
Vdc max controller has been de-activated, since controller is not capable of keeping DC-link voltage
(r0026) within limits (P2172).
Occurs if main supply voltage (P0210) is permanently too high
Occurs if motor is driven by an active load, causing motor to go into regenerative mode
Occurs at very high load inertias, when ramping down
Diagnose & Remedy
Check the following:
Input voltage (P0210) must lie within range
Load must be match
A0911 Vdc-max controller active
Possible Causes
Vdc max controller is active; so ramp-down times will be increased automatically to keep DC-link
voltage (r0026) within limits (P2172).
A0912 Vdc-min controller active
Possible Causes
Vdc min controller will be activated if DC-link voltage (r0026) falls below minimum level (P2172).
The kinetic energy of the motor is used to buffer the DC-link voltage, thus causing deceleration of the
drive!
So short mains failures do not necessarily lead to an undervoltage trip.
A0920 ADC parameters not set properly
Possible Causes
ADC parameters should not be set to identical values, since this would produce illogical results.
Fault value = 0: Parameter settings for output identical
1: Parameter settings for input identical

Possible Causes
Both JOG right and JOG left (P1055/P1056) have been requested. This freezes the RFG output
frequency at its current value.
A0936 PID Autotuning Active
Possible Causes
PID Autotuning (P2350) selected or running
A0952 Belt Failure Warning
Possible Causes
Load conditions on motor indicate belt failure or mechanical fault.
