Before Commencing the Installation
●
Disconnect the power supply of the device
●
Ensure that devices cannot be accidentally restarted
●
Verify isolation from the supply
●
Earth and short circuit the device
●
Cover or enclose any adjacent live components
●
Follow the engineering instructions (IL04020001E) for the
device concerned
●
Only suitably qualified personnel in accordance with
EN 50110-1/-2 (VDE 0105 Part 100) may work on this
device/system
●
Before installation and before touching the device ensure
that you are free of electrostatic charge
●
The functional earth (FE, PES) must be connected to the
protective earth (PE) or the potential equalization. The
system installer is responsible for implementing this
connection
●
Connecting cables and signal lines should be installed so
that inductive or capacitive interference does not impair
the automation functions
●
Install automation devices and related operating elements
in such a way that they are well protected against
unintentional operation
●
Suitable safety hardware and software measures should
be implemented for the I/O interface so that an open
circuit on the signal side does not result in undefined
states in the automation devices
●
Ensure a reliable electrical isolation of the extra-low
voltage of the 24V supply. Only use power supply units
complying with IEC 60364-4-41 (VDE 0100 Part 410) or
HD384.4.41 S2
●
Deviations of the input voltage from the rated value must
not exceed the tolerance limits given in the specifications,
otherwise this may cause malfunction and dangerous
operation
●
Emergency stop devices complying with IEC/EN 60204-1
must be effective in all operating modes of the automation
devices. Unlatching the emergency-stop devices must not
cause a restart
●
Devices that are designed for mounting in housings or
control cabinets must only be operated and controlled
after they have been installed and with the housing closed.
Desktop or portable units must only be operated and
controlled in enclosed housings
VSD Series II Variable Speed Micro Drives (VSM II)
●
Measures should be taken to ensure the proper restart of
programs interrupted after a voltage dip or failure. This
should not cause dangerous operating states even for a
short time. If necessary, emergency-stop devices should
be implemented
●
Wherever faults in the automation system may cause
injury or material damage, external measures must be
implemented to ensure a safe operating state in the event
of a fault or malfunction (for example, by means of
separate limit switches, mechanical interlocks, and so on)
●
Depending on their degree of protection, adjustable
frequency drives may contain live bright metal parts,
moving or rotating components, or hot surfaces during and
immediately after operation
●
Removal of the required covers, improper installation, or
incorrect operation of motor or adjustable frequency drive
may cause the failure of the device and may lead to
serious injury or damage
●
The applicable national accident prevention and safety
regulations apply to all work carried out on live adjustable
frequency drives
●
The electrical installation must be carried out in
accordance with the relevant regulations (for example,
with regard to cable cross sections, fuses, PE)
●
Transport, installation, commissioning, and maintenance
work must be carried out only by qualified personnel
(IEC 60364, HD 384 and national occupational safety
regulations)
●
Installations containing adjustable frequency drives must
be provided with additional monitoring and protective
devices in accordance with the applicable safety
regulations. Modifications to the adjustable frequency
drives using the operating software are permitted
●
All covers and doors must be kept closed during operation
●
To reduce hazards for people or equipment, the user must
include in the machine design measures that restrict the
consequences of a malfunction or failure of the drive
(increased motor speed or sudden standstill of motor).
These measures include:
●
Other independent devices for monitoring safety-related
variables (speed, travel, end positions, and so on)
●
Electrical or non-electrical system-wide measures
(electrical or mechanical interlocks)
●
Never touch live parts or cable connections of the
adjustable frequency drive after it has been
disconnected from the power supply. Due to the charge
in the capacitors, these parts may still be live after
disconnection. Fit appropriate warning signs

Definitions and Symbols
WARNING
This symbol indicates high voltage. It calls your
attention to items or operations that could be dangerous
to you and other persons operating this equipment.
Read the message and follow the instructions carefully.
This symbol is the “Safety Alert Symbol.” It occurs with
either of two signal words: CAUTION or WARNING, as
described below.
WARNING
Indicates a potentially hazardous situation which, if not
avoided, can result in serious injury or death.
CAUTION
Indicates a potentially hazardous situation which, if not
avoided, can result in minor to moderate injury, or serious
damage to the product. The situation described in the
CAUTION may, if not avoided, lead to serious results.
Important safety measures are described in CAUTION (as
well as WARNING).
Warnings and Cautions
CAUTION
When selecting the cable cross-section, take the voltage
drop under load conditions into account.
The consideration of other standards (for example, VDE 0113
or VDE 0289) is the responsibility of the user.
CAUTION
The specified minimum PE conductor cross-sections
(EN 50178, VDE 0160) must be maintained.
WARNING
With frequency inverters, only AC/DC sensitive residual
current circuit breakers (RCD type B) are to be used
(EN 50178, IEC 755).
CAUTION

Only use cables, protective switches, and contactors that
feature the indicated permissible nominal current value.
CAUTION
Debounced inputs may not be used in the safety circuit
diagram.
Ground contact currents in frequency inverters are greater
than 3.5 mA (AC). According to product standard IEC/EN
61800-5-1, an additional equipment grounding conductor
must be connected, or the cross-section of the equipment
grounding conductor must be at least 0.39 in
2
(10 mm2).
WARNING
The components in the frequency inverter’s power
section remain energized up to five (5) minutes after the
supply voltage has been switched off (intermediate
circuit capacitor discharging time).
Pay attention to hazard warnings!
WARNING
Discharge yourself on a grounded surface before
touching the control signal terminals and the controller
PCB. This protects the device from destruction by
electrostatic discharge.
WARNING
On the control signal and the connection terminals of the
frequency inverter, no leakage resistance tests are to be
performed with an insulation tester.
WARNING
Wait at least 5 minutes after switching the supply
voltage off before you disconnect a connection on the
connection terminals (L1, L2/N, L3, U/T1, V/T2, W/T3,
R+, R–) of the frequency inverter.
WARNING
Commissioning is only to be completed by qualified
technicians.
WARNING
Hazardous voltage!
The safety instructions on Page xi must be followed.
WARNING
The components in the frequency inverter’s power
section are energized if the supply voltage (line voltage)
is connected. For instance: power terminals L1, L2/N, L3,
R+, R–, U/T1, V/T2, W/T3.
The control signal terminals are isolated from the line
power potential.
There can be a dangerous voltage on the relay terminals
(22 to 26) even if the frequency inverter is not being
supplied with line voltage (for example, integration of
relay contacts in control systems with 230 Vac).
WARNING
Following a shutdown (fault, line voltage off), the motor
can start automatically (when the supply voltage is
switched back on) if the automatic restart function has
been enabled.

CAUTION
Debounced inputs may not be used in the safety circuit
diagram.
Any contactors and switching devices on the power side are
not to be opened during motor operation. Inching operation
using the power switch is not permitted.
Contactors and switching devices (repair and maintenance
switches) on the motor side must never be opened while the
motor is in operation when the frequency inverter is set to
speed control operating mode (P11.8 = 1).
Inching operation of the motor with contactors and switching
devices in the output of the frequency inverter is not
permitted.
CAUTION
Debounced inputs may not be used in the safety circuit
diagram.
Make sure that there is no danger in starting the motor.
Disconnect the driven machine if there is a danger in an
incorrect operational status.
WARNING
If a start signal is present, the drive is restarted
automatically, if P3.1 = 0 is set (REAF = Restart after
FAULT) and the error message has been acknowledged
(Reset).
CAUTION
A high torque at low speed leads to a high thermal load on
the motor.
CAUTION
Debounced inputs may not be used in the safety circuit
diagram. DC braking results in additional heating of the
motor. Configure the brake torque, set via braking current
(P12.1) and the braking duration (P12.2 and P12.4), as low as
possible.
CAUTION
Debounced inputs may not be used in the safety circuit
diagram.
The motor parameters must be identical in both parameter
groups (P7 and P14).
CAUTION
Although the registers to be written are consecutive, the ID
numbers of the parameter list are not. Only the ID numbers
in the process data list are consecutive.
CAUTION
Fuses and cables selected must always comply with the
applicable regulations at the installation site.
WARNING
If a start command is present at a digital input (DI1–DI6)
assigned at P3.21, the sequence control also starts
automatically (without switch edge) when the power
supply is switched on (for example, after a power supply
failure).
CAUTION
A high torque at low speed causes a high thermal load on the
motor. If temperatures are too high, the motor should be
equipped with an external fan.

About this Manual
Input Supply Voltages
The rated operating voltages stated in the following table are
based on the standard values for networks with a grounded
star point.
In ring networks (as found in Europe) the rated voltage at the
transfer point of the power supply companies is the same as
the value in the consumer networks (for example, 230V, 400V).
In star networks (as found in North America), the rated
voltage at the transfer point of the utility companies is higher
than in the consumer network. Example: 120V 115V,
240V 230V, 480V 460V.
Units
Every physical dimension included in this manual uses
imperial units. For the purpose of the equipment’s UL
certification, some of these dimensions are accompanied by

Features
The VSM II frequency inverter converts the voltage and frequency of an existing AC network
into DC voltage. This DC voltage is used to generate a three-phase AC voltage with adjustable
frequency and assigned amplitude values for the variable speed control of three-phase
asynchronous motors.

VSM II Series Overview
When connecting multiple motors in parallel to the output of
a frequency inverter, the motor currents are added
geometrically—separated by effective and idle current
components. When you select a frequency inverter, make
sure that it can supply the total resulting current. If
necessary, for dampening and compensating the deviating
current values, motor reactors or sinusoidal filters must be
connected between the frequency inverter and the motor.
The parallel connection of multiple motors in the output of
the frequency inverter is only permitted with V/Hzcharacteristic curve control.
If you connect a motor to an operational frequency inverter,
the motor draws a multiple of its rated operational current.
When you select a frequency inverter, make sure that the
starting current plus the sum of the currents of the running
motors will not exceed the rated output current of the
frequency inverter.
Switching in the output of the frequency inverter is only
permitted with V/Hz-characteristic curve control.
The speed control with slip compensation (P11.8) increases
the drive dynamics and optimizes the output. For this the
frequency inverter processes all motor data in an electrical
image.
The speed control operating mode (P11.8) must only be used
with single drives (one motor at the output of the frequency
inverter). The rated current of the motor must be assigned to
the rated operational current of the frequency inverter (same
rating).
When selecting the drive, the following criteria must be
known:
●
Type of motor (three-phase asynchronous motor)
●
Input voltage = rated operating voltage of the motor
(for example, 3 AC~400V)
●
Rated motor current (guide value, dependent on the circuit
type and the supply voltage)
●
Load torque (quadratic, constant)
●
Starting torque
●
Ambient temperature (rated value 122°F [50°C])

VSM II Series Overview
Proper Use
The VSM II frequency inverters are not domestic appliances.
They are designed only for industrial use as system
components.
The VSM II frequency inverters are electrical apparatus for
controlling variable speed drives with three-phase motors.
They are designed for installation in machines or for use in
combination with other components within a machine or
system.
After installation in a machine, the frequency inverters must
not be taken into operation until the associated machine has
been confirmed to comply with the safety requirements of
Machinery Safety Directive (MSD) 89/392/EEC (meets the
requirements of EN 60204). The user of the equipment is
responsible for ensuring that the machine use complies with
the relevant EU Directives.
The CE markings on the VSM II frequency inverter confirm
that, when used in a typical drive configuration, the apparatus
complies with the European Low Voltage Directive (LVD) and
the EMC Directives (Directive 73/23/EEC, as amended by
93/68/EEC and Directive 89/336/EEC, as amended by
93/68/EEC).
In the described system configurations, VSM II frequency
inverters are suitable for use in public and non-public
networks.
A connection to IT networks (networks without reference to
earth potential) is permissible only to a limited extent,
because the device’s built-in filter capacitors connect the
network with the earth potential (enclosure). On earth free
networks, this can lead to dangerous situations or damage to
the device (isolation monitoring required).
To the output of the frequency inverter (terminals U, V, W)
you must not:
●
connect a voltage or capacitive loads (for example, phase
compensation capacitors)
●
connect multiple frequency inverters in parallel
●
make a direct connection to the input (bypass)
Observe the technical data and connection requirements. For
additional information, refer to the equipment nameplate or
label at the frequency inverter, and the documentation.
Any other usage constitutes improper use.
Maintenance and Inspection
Provided that the general rating data (see “Nameplate Rating
Data” on Page 5) and the special technical data (see “Special
Technical Data” on Page 140) of the ratings concerned are
observed, the VSM II frequency inverters are maintenance
free. However, external influences may affect the function
and the lifespan of the VSM II frequency inverter. We
therefore recommend that the devices are checked regularly
and the following maintenance measures are carried out at
the specified intervals.
Maintenance Measures and Intervals
Maintenance Measure Maintenance Interval
Clean cooling vents (cooling slits) If required
Check the fan function 6–24 months (depending on the environment)
Filter in the switching cabinet doors (see manufacturer specifications) 6–24 months (depending on the environment)
Check the tightening torques of the terminals (control signal terminals, power terminals) Regularly
Check connection terminals and all metallic surfaces for corrosion 6–24 months (depending on the environment)
Charge capacitors 12 months, see “Charging DC Link Capacitors” on Page 15
There are no plans for replacing or repairing individual
components of VSM II frequency inverters.
If the VSM II frequency inverter is damaged by external
influences, repair is not possible. Dispose of the device in
accordance with the respectively applicable environmental
laws and provisions for the disposal of electrical or electronic
devices.

VSM II Series Overview
Storage
If the frequency inverter is stored before use, suitable
ambient conditions must be ensured at the site of storage:
●
Storage temperature: –40° to 158°F (–40° to 70°C)
●
Relative average air humidity: <95%, non condensing
(EN 50178)
●
To prevent damage to the DC link capacitors, storage
times longer than 12 months are not recommended
(see “Charging DC Link Capacitors” below)
Charging DC Link Capacitors
After long storage times or long down times without a power
supply (>12 months), the capacitors in the DC link must
undergo controlled recharging, in order to avoid damage.
For this, the VSM II frequency inverters must be fed with a
regulated DC power supply unit via two input connection
terminals (for example, L1, L2/N). To avoid any possible
excessive leakage currents from the capacitors, the inrush
current should be limited to around 300 to 800 mA
(depending on the rating). In this case, the frequency inverter
must not be enabled (no start signal). The DC voltage must
then be set to the values of the corresponding DC link
voltage (U
time).

While planning the project, consider a symmetrical
distribution to the three external conductors, if multiple
frequency inverters with single-phase supplies are to be
connected. The total current of all single-phase consumers is
not to cause an overload of the neutral conductor
(N-conductor).
The connection and operation of frequency inverters to
asymmetrically grounded TN networks (phase-grounded
Delta network “Grounded Delta”, USA) or non-grounded or
high-resistance grounded (over 30 ohms) IT networks is only
conditionally permissible.
If the VSM II frequency inverters are connected to an
asymmetrically grounded network or to an IT network
(non-grounded, insulated), the internal interference
suppression filter must be disconnected (unscrew the screw
marked EMC, see “Electrical Installation” on Page 30). The
required filtering for electromagnetic compatibility (EMC) is
then no longer present.
Measures for electromagnetic compatibility are mandatory in
a drive system in order to meet the legal requirements for
EMC and low voltage regulations.
Good grounding measures are a prerequisite for the effective
insert of further measures such as shielding or filters.
Without respective grounding measures, further steps are
superfluous.

Engineering
Voltage Balance
Because of the uneven loading on the conductor, and with
the direct connection of greater power ratings, deviations
from the ideal voltage form and asymmetrical voltages can
be caused in three-phase AC power networks. These
asymmetric divergences in the input voltage can lead to
different loading of the diodes in input rectifiers with
three-phase supplied frequency inverters, and as a result,
an advance failure of this diode.
In the project planning for the connection of three-phase
supplied frequency inverters (VSxxx2x3, VSxxx4, VSxxx5),
consider only AC power networks that handle permitted
asymmetric divergences in the input voltage +3%.
If this condition is not fulfilled, or symmetry at the connection
location is not known, the use of an assigned main choke is
recommended.
Total Harmonic Distortion (THD)
The THD (Total Harmonic Distortion) is a measurement for
the occurring harmonic distortion of the sinusoidal oscillation
(input power side) input variables with the frequency
inverter. It is given in percent of the total value.

Input Reactors
A input reactor (also called commutation inductor) increases
the inductance of the power supply line. This extends the
current flow period and dampens input deviations.
On frequency inverters, a input reactor limits the input
feedback to permissible values. The harmonic current
emissions that are fed back into the input network (“input
feedback”) are reduced. This reduces the input-side apparent
current to about 30%.
Toward the frequency inverter, the input reactors dampen
the interference from the supply network. This increases the
withstand voltage of the frequency inverter and lengthens
the lifespan (diodes of the input power rectifier, intermediate
circuit capacitors).
For the operation of the VSM II frequency inverter, the
application of main chokes is not necessary.
We do recommend, however, that an upstream main choke
is used because the network quality is not known in most
cases.
While planning the project, consider that a input reactor is
only assigned to a single frequency inverter for isolation.
Using a large input reactor for multiple small frequency
inverters should therefore be avoided if at all possible.
When using an adapting transformer (assigned to a single
frequency inverter), a main choke is not necessary.
Input reactors are designed based on the input current (I
of the frequency inverter. Input chokes and the assignment
to VSM II frequency inverters are explained in the appendix.

Idle Power Compensation Devices
Compensation on the power supply side is not required for
VSM II series frequency inverters. From the AC power
supply network, they take on very little reactive power of the
fundamental harmonics (cos ~ 0.98).
In the AC power networks with non-choked idle current
compensation devices, current deviations can enable parallel
resonance and undefinable circumstances.
In the project planning for the connection of frequency
inverters to AC power networks with undefined
circumstances, consider using main chokes.

Fuses and Cable Cross-Sections
The fuses and wire cross-sections allocated for power-side
connections depend on the rated input current I
frequency inverter (without input reactor).
LN
of the
CAUTION
When selecting the cable cross-section, take the voltage
drop under load conditions into account.
The consideration of other standards (for example, VDE 0113
or VDE 0289) is the responsibility of the user.
The national and regional standards (for example VDE 0113,
EN 60204) must be observed and the necessary approvals
(for example UL) at the site of installation must be fulfilled.
When the device is operated in a UL-approved system, use
only UL-approved breakers, fuses, fuse bases, and cables.
The leakage currents to ground (to EN 50178) are greater
than 3.5 mA. The connection terminals marked PE and the
housing must be connected with the ground circuit.
The leakage currents for the individual performance variables
are listed on Page 140 .
CAUTION
The specified minimum PE conductor cross-sections
(EN 50178, VDE 0160) must be maintained.
Choose the cross-section of the PE conductor in the motor
lines at least as large as the cross-section of the phase lines
(U, V, W).
Cables and Fuses
The cross-sections of the cables and line protection fuses
used must correspond with local standards.
For an installation in accordance with UL guidelines, the
fuses and copper cable that are UL-approved and have a
heat-resistance of 140° to 167°F (60° to 75°C) are to be used.
Use power cables with insulation according to the specified
input voltages for the permanent installation. A shielded
cable is not required on the input side.
A completely (360°) shielded low impedance cable is
required on the motor side. The length of the motor cable
depends on the RFI class and must not exceed 98 ft (30m)
for the VSM II.
Residual-Current Device (RCD)
RCD (Residual Current Device): Residual current device,
residual current circuit breaker (FI circuit breaker).
Residual current circuit breakers protect persons and animals
from the existence (not the origination) of impermissibly high
contact voltages. They prevent dangerous, and in some
cases deadly injuries caused by electrical accidents, and also
serve as fire prevention.
WARNING
With frequency inverters, only AC/DC sensitive residual
current circuit breakers (RCD type B) are to be used
(EN 50178, IEC 755).
Identification on the Residual-Current Circuit-Breakers
AC/DC sensitive
(RCD, type B)
Frequency inverters work internally with rectified AC
currents. If an error occurs, the DC currents can block a type
A RCD circuit breaker from triggering and therefore disable
the protective functionality.
CAUTION
Debounced inputs may not be used in the safety circuit
diagram.
Residual current circuit breakers (RCD) are only to be
installed between the AC power supply network and the
frequency inverter.
Safety-relevant leakage currents can occur while handling
and when operating the frequency inverter, if the frequency
inverter is not grounded (because of a fault).
Leakage currents to ground are mainly caused by foreign
capacities with frequency inverters; between the motor
phases and the shielding of the motor cable and via the
Y-capacitors of the noise filter. The size of the leakage
current is mainly dependent upon the:
●
length of the motor cable
●
shielding of the motor cable
●
height of the pulse frequency (switching frequency of the
inverter)
●
design of the noise filter
●
grounding measures at the site of the motor
VSD Series II Variable Speed Micro Drives (VSM II) LIT-12011835—May 2013 www.johnsoncontrols.com
19
Engineering
The leakage current to ground is greater than 3.5 mA with a
frequency inverter. Based on the requirements of EN 50178,
an increased ground (PE) has to be connected. The cable
cross-section must be at least 10 mm
2
or consist of two
separately connected ground cables.
Residual current circuit breakers must be suitable for:
●
the protection of installations with DC current component
in case of fault scenario (RCD type B)
●
high leakage currents (300 mA)
●
brief discharges of pulse current spikes
Input Contactor
The input contactor enables an operational switching on and
off of the supply voltage for the frequency inverter, and
switching off in case of a fault.
The input contactor is designed based on the input current
(I
) of the frequency inverter and the utilization category
LN
AC-1 (IEC 60947). Input contactors and the assignment to
VSM II frequency inverters are explained in the appendix.
While planning the project, make sure that inching operation
is not done via the input contactor of the frequency inverter
on frequency-controlled drives, but through a controller input
of the frequency inverter.
The maximum permitted operating frequency of the input
voltage with the VSM II frequency inverter is one time per
minute (normal operation).
EMC Measures
Electrical components in a system (machine) have a
reciprocal effect on each other. Each device not only emits
interference but is also affected by it. The interference can
be produced by galvanic, capacitive, and/or inductive
sources, or by electromagnetic radiation. In practice, the limit
between line-conducted interference and emitted
interference is around 30 MHz. Above 30 MHz, cables and
conductors act like antennas that radiate electromagnetic
waves.
Electromagnetic compatibility (EMC) for frequency controlled
drives (variable speed drives) is implemented in accordance
with product standard IEC/EN 61800-3. This includes the
complete power drive system (PDS), from the input supply to
the motor, including all components, as well as cables (see
figure on Page 16 ). This type of drive system can consist of
several individual drives.
The generic standards of the individual components in a PDS
compliant with IEC/EN 61800-3 do not apply. These
component manufacturers, however, must offer solutions
that ensure standards-compliant use.
In Europe, maintaining the EMC guidelines is mandatory.
A declaration of conformity (CE) always refers to a “typical”
power drive system (PDS). The responsibility to comply with
the legally stipulated limit values and thus the provision of
electromagnetic compatibility is ultimately the responsibility
of the end user or system operator. This operator must also
take measures to minimize or remove emission in the
environment concerned (see figure below). He must also use
means to increase the interference immunity of the devices
of the system.
With their high interference immunity up to category C3,
VSM II frequency inverters are ideal for use in harsh

With line-conducted emission, type VS…-MEM00 frequency
inverters (with integrated interference suppression filter)
ensure the observance of the sensitive limit values of
category C2 in environment 1. This requires an
EMC-compliant installation (see Page 30 ) and the
observance of the permissible motor cable lengths and
maximum switching frequency (f
) of the inverter.
PWM
Type VS…-M0000 frequency inverters can comply with the
limit values of category C1 in environment 1 when used in
conjunction with an assigned external interference

Motor Selection
General recommendations for motor selection:
●
Use three-phase powered asynchronous motors with
short-circuit rotors and surface cooling, also called
asynchronous motors or standard motors for the
frequency-controlled drive system (PDS). Other
specifications such as external rotor motors, slip-ring
motors, reluctance motors, synchronous or servo
motors can also be run with a frequency inverter, but
normally require additional planning and discussion
with the motor manufacturer
●
Use only motors with at least heat class F
(311°F [155°C] maximum steady state temperature)
●
Four-pole motors are preferred (synchronous speed:
1500 min
●
Take the operating conditions into account for S1 operation
–1
at 50 Hz or 1800 min
–1
at 60 Hz)
(IEC 60034-1)
●
When operating multiple motors in parallel on one
frequency inverter, the motor output should not be more
than three power classes apart
●
Ensure that the motor is not overdimensioned. If a motor
in speed control mode is underdimensioned, the motor
rating must only be one rating level lower
Connecting Motors in Parallel
The VSM II frequency inverters allow parallel operation of
several motors in V/Hz control mode:
●
V/Hz control: several motors with the same or different
rated operational data. The sum of all motor currents must
be less than the frequency inverter’s rated operational
current
●
V/Hz control: parallel control of several motors. The sum of
the motor currents plus the motors’ inrush currents must
be less than the frequency inverter’s rated operational
current
Parallel operation at different motor speeds can be
implemented only by changing the number of pole pairs and/
or changing the motor’s transmission ratio.
CAUTION
Debounced inputs may not be used in the safety circuit
diagram.
If you are connecting multiple motors on one frequency
inverter, you must design the contactors for the individual
motors according to utilization category AC-3.
Selecting the motor contactor is done according to the rated
operational current of the motor to be connected.

Connecting motors in parallel reduces the load resistance at
the frequency inverter output. The total stator inductance is
lower and the leakage capacity of the lines greater. As a
result, the current distortion is greater than in a single-motor
circuit. To reduce the current distortion, you should use
motor reactors (see [1] in figure above) in the output of the
frequency inverter.
The current consumption of all motors connected in parallel
must not exceed the frequency inverter’s rated output
current I2N.
Electronic motor protection cannot be used when operating
the frequency inverter with several parallel connected
motors. You must, however, protect each motor with
thermistors and/or overload relays.
The use of a motor protective circuit breaker at the frequency
inverter’s output can lead to nuisance tripping.

With the 87-Hz characteristic curve, the motor also works in
the range from 50 to 87 Hz with an unattenuated field. The

Installation
EMC Installation
The responsibility to comply with the legally stipulated limit
values and thus the provision of electromagnetic
compatibility is the responsibility of the end user or system
operator. This operator must also take measures to minimize
or remove emissions in the environment concerned (see
figure on Page 20). He must also use means to increase the
interference immunity of the system devices.
In a drive system (PDS) with frequency inverters, you should
take measures for electromagnetic compatibility (EMC) while
doing your planning, because changes or improvements to
the installation site, which are required in the installation or
while mounting, are normally associated with additional
higher costs.
The technology and system of a frequency inverter cause the
flow of high frequency leakage current during operation. All
grounding measures must therefore be implemented with
low impedance connections over a large surface area.
With leakage currents greater than 3.5 mA, in accordance
with VDE 0160 or EN 60335, either
●
the protective conductor must have a cross-section
●
the protective conductor must be open-circuit monitored,
or
●
the second protective conductor must be fitted
For an EMC-compliant installation, we recommend the
following measures:
●
Installation of the frequency inverter in a metallic,
electrically conducting enclosure with a good connection
to earth
●
Shielded motor cables (short cable lengths)
Ground all conductive components and housings in a drive
system using as short a line as possible with the greatest
possible cross-section (Cu-braid).
EMC Measures in the Control Panel
For EMC-compatible installation, connect all metallic parts of
the device and the switching cabinet together over broad
surfaces and so that high-frequencies will be conducted.
Mounting plates and cabinet doors should make good
contact and be connected with short HF-braided cables.
Avoid using painted surfaces (anodized, chromized). An
overview of all EMC measures is provided in the figure on
Page 29.
10 mm
2
Install the frequency inverter as directly as possible (without
spacers) on a metal plate (mounting plate).
Route input and motor cables in the switch cabinet as close
to the ground potential as possible. This is because free
moving cables act as antennas.
When laying HF cables (for example, shielded motor cables)
or suppressed cables (for example, input supply cables,
control circuit and signal cables) in parallel, a minimum
clearance of 11.81 in (300 mm) should be ensured in order to
prevent the radiation of electromagnetic energy. Separate
cable routing should also be ensured when large voltage
potential differences are involved. Any necessary crossed
cabling between the control signal and power cables should
always be implemented at right angles (90 degrees).
Never lay control or signal cables in the same duct as power
cables. Analog signal cables (measured, reference and
correction values) must be shielded.
Earthing
The ground connection (PE) in the cabinet should be
connected from the input supply to a central earth point
(mounting plate). All protective conductors should be routed
in star formation from this earth point and all conductive
components of the PDS (frequency inverter, motor reactor,
motor filter, main choke) are to be connected.
Avoid ground loops when installing multiple frequency
inverters in one cabinet. Make sure that all metallic devices
that are to be grounded have a broad area connection with
the mounting plate.
Screen Earth Kit
Cables that are not shielded work like antennas (sending,
receiving). Make sure that any cables that may carry
disruptive signals (for example, motor cables) and sensitive
cables (analog signal and measurement values) are shielded
apart from one another with EMC-compatible connections.
The effectiveness of the cable shield depends on a good
shield connection and a low shield impedance.
Use only shields with tinned or nickel-plated copper braiding.
Braided steel shields are unsuitable.
Control and signal lines (analog, digital) should always be
grounded on one end, in the immediate vicinity of the supply
voltage source (PES).

Prevent the shielding from becoming unbraided, for example,
by pushing the separated plastic covering over the end of the
shielding or with a rubber grommet on the end of the
shielding. As an alternative, in addition to a broad area cable
clip, you can also twist the shielding braid at the end and
connect to protective ground with a cable clip. To prevent
EMC disturbance, this twisted shielding connection should
be made as short as possible (see figure below).

Shielded, four-wire cable is recommended for the motor
cables. The green-yellow line of this cable connects the

The cable hold down clamps contained in the scope of
delivery can be mounted on the cable clamp plate of the
power section.
The control lines should be shielded and twisted. The
shielding is exposed on one side (PES), on the cable hold
down clamps on the frequency inverter for instance.
Prevent the shielding from becoming unbraided, for example,
by pushing the separated plastic covering over the end of the
shielding or with a rubber grommet on the end of the
shielding.
Prevent the Shield from Becoming Unbraided
Prevent any unraveling on the other end of the control line
with a rubber grommet. The shielding braid is not to make
any connection with protective ground here because this
would cause problems with an interference loop.

As an alternative, in addition to a broad area cable clip, you
can also twist the shielding braid at the end and connect to

disturbance, this twisted shielding connection should be
made as short as possible (see figure on Page 33).

Insulation Testing
The VSM II series frequency inverters are tested, delivered
and require no additional testing.
WARNING
On the control signal and the connection terminals of the
frequency inverter, no leakage resistance tests are to be
performed with an insulation tester.
WARNING
Wait at least 5 minutes after switching the supply
voltage off before you disconnect a connection on the
connection terminals (L1, L2/N, L3, U/T1, V/T2, W/T3,
R+, R–) of the frequency inverter.
If insulation testing is required in the power circuit of the
PDS, you must consider the following measures.
Testing the Motor Cable Insulation
Disconnect the motor cable from connection terminals U/T1,
V/T2 and W/T3 of the frequency inverter and from the motor
(U, V, W). Measure the insulation resistance of the motor
cable between the individual phase conductors and between
the phase conductor and the protective conductor.
The insulation resistance must be greater than 1M ohm.
Installation
Testing the Input Cable Insulation
Disconnect the power cable from the input supply network
and from connection terminals L1, L2/N and L3 of the
frequency inverter. Measure the insulation resistance of the
input cable between the individual phase conductors and
between each phase conductor and the protective
conductor.
The insulation resistance must be greater than 1M ohm.
Testing the Motor Insulation
Disconnect the motor cable from the motor (U, V, W) and
open the bridge circuits (star or delta) in the motor terminal
box. Measure the insulation resistance of the individual
motor windings. The measurement voltage must at least
match the rated voltage of the motor but is not to exceed
1000V.
The insulation resistance must be greater than 1M ohm.
Consider the information from the motor manufacturer in
testing the insulation resistance.

Operational Hazard Warnings
Observe the following Warnings and Cautions.
Operation
WARNING
Commissioning is only to be completed by qualified
technicians.
WARNING
Hazardous voltage!
The safety instructions on Page xi must be followed.
WARNING
The components in the frequency inverter’s power
section are energized if the supply voltage (line voltage)
is connected. For instance: power terminals L1, L2/N, L3,
R+, R–, U/T1, V/T2, W/T3.
The control signal terminals are isolated from the line
power potential.
There can be a dangerous voltage on the relay terminals
(22 to 26) even if the frequency inverter is not being
supplied with line voltage (for example, integration of
relay contacts in control systems with 230 Vac).
WARNING
The components in the frequency inverter’s power
section remain energized up to five (5) minutes after the
supply voltage has been switched off (intermediate
circuit capacitor discharging time).
Pay attention to hazard warnings!
CAUTION
Debounced inputs may not be used in the safety circuit
diagram.
Any contactors and switching devices on the power side are
not to be opened during motor operation. Inching operation
using the power switch is not permitted.
Contactors and switching devices (repair and maintenance
switches) on the motor side must never be opened while the
motor is in operation when the frequency inverter is set to
speed control operating mode (P11.8 = 1).
Inching operation of the motor with contactors and switching
devices in the output of the frequency inverter is not
permitted.
CAUTION
Debounced inputs may not be used in the safety circuit
diagram.
Make sure that there is no danger in starting the motor.
Disconnect the driven machine if there is a danger in an
incorrect operational status.
Note: The START button is only functional if the KEYPAD
operating mode is activated.
The STOP button is active in all operating modes. It
can be deactivated with parameter (P6.16 = 0).
Note: Operating ranges must be approved by the motor
manufacturer if motors are to be operated with
frequencies higher than the standard 50 or 60 Hz,
otherwise the motors could be damaged.
DANGER

Connect the frequency inverter according to the connection
example for simple commissioning with the specified default
settings (see connecting example above).
If the connections for the setpoint value potentiometer
cannot be clearly allocated with terminals 1, 2 and 3, you
should set the potentiometer to about 50% before giving the
start release (FWD/REV) for the first time.
When the specified power supply is applied to connection
terminal L2/N and L3 (VSxxx0) or L1 and L2/N (VSxxx2x4) or
L1, L2/N and L3 (VSxxx2x3, VSxxx4, VSxxx5), the LCD
display lights up and all segments are displayed briefly.
The frequency inverter runs a self-test automatically when
the power is applied.
The arrows ( ) in the top status line of the LCD display
show the operating status:
●
READY = proper operating status
●
STOP = stop (no start command)
The arrows ( ) in the bottom status line show the controller
commands. Actuation is done via the control signal terminals
(I/O = Control Input/Output) in the factory setting.
The FWD mark (forward) designates the basic rotational
direction (phase sequence for a clockwise rotating field) on
connection terminals U/T1, V/T2 and W/T3.
The operating data of the output frequency is shown in the
LCD display in alternating sequence with M1.1 and 0.00 Hz.
The arrow in the left-hand status line indicates menu level

A controlled run-down can be set using parameter P6.8
(STOP function) (P6.8 = 1).
The relevant deceleration time is set in parameter P6.6. The
acceleration time are set in parameter P6.5.
Information on settings and the description of the
parameters used here are provided in “Drives Control (P6)”
on Page 80.
The acceleration and deceleration ramps specify the
time change for the output frequency: from zero to

Error and Warning Messages
Error and Warning Messages
Introduction
VSM II frequency inverters have several internal monitoring
functions. When deviations from the correct operating status
are detected, faults (FAULT) and warning messages
(ALARM) are differentiated between.
Error Messages
Faults can cause defective functionality and technical
defects. The inverter (frequency inverter output) is
automatically disabled if a fault is detected. After this, the
connected motor comes to a stop freely.
Error messages are shown on the display with an arrowhead
under FAULT and with the error code F… (F1 = last fault,
F2 = second to last, and so on).
Example of an Error Message (Undervoltage)
RUN STOP ALARM FAULTREADY
REF
MON
PAR
FLT
FWD REV I/O KEYPAD BUS
Fault Log (FLT)
The last nine faults can be called up and shown in succession
in the fault log (FLT).
Select the FLT menu level ( ). Use the arrow buttons and
to call the faults F1–F9 individually. Every error message is
stored with the time of the error occurrence under d (day), H
(hour) and m (minute). The call is made with the OK button,
and the selection with the and arrow buttons.
The content of the error memory is cleared when the factory
setting is activated. When you press the BACK/RESET
button, the display of the menu level ( ) flashes and the
STOP button is held down for around 5 seconds.
Activating the factory settings will reset all parameters.
Alarm Messages
A warning message signals possible damage and indicates
impending errors that can still be prevented, such as an
excessively high temperature rise.
Warning messages appear on the display with an arrow
under ALARM and AL with the respective code number. The
code numbers for faults and warning messages are identical.
Acknowledge Fault Message (Reset)
The current error message flashes (for example, F1 09). It
can be acknowledged by pressing the OK button followed by
BACK/RESET or by actuating DI5 (default settings control
signal terminal 15). The displayed error then automatically
stops flashing, the four horizontal bars (Reset) are shown and
the error message is then displayed continuously. The arrow
point underneath FAULT disappears.
WARNING
If a start signal is present, the drive is restarted
automatically, if P3.1 = 0 is set (REAF = Restart after
FAULT) and the error message has been acknowledged
(Reset).
The current fault message indication (F1...) is cleared when
the supply voltage is interrupted or when you press the OK
button followed by BACK/RESET. The indication goes out
and the arrow tip flashes at menu level MON.

If a warning message occurs, the frequency inverter remains
active (READY, RUN).
In the given example (AL 50 = current setpoint signal
4–20 mA interrupted), the drive stops following the absence
of a reference value. If no more measures are introduced
because of the warning message (for example, a shutdown),
the drive can start again automatically in the example AL 50
when the current signal returns (for example, a contact fault
in the signal line).
The alarm message (AL) is displayed alternating with the
active operational display value.
The table on Page 55 shows the error codes, their possible
causes, and indicates correction measures.

General Information on Menu Navigation
By applying the specified supply voltage to the connection
terminals L2/N and L3 (VSxxx0), L1 and L2/N (VSxxx2x4) or
L1, L2/N and L3 (VSxxx2x3, VSxxx4), the frequency inverter
automatically runs the following functions:
●
The lighting of the LCD display is switched on and all
segments are actuated briefly
●
After the self-test, the top status line of the LCD display
indicates that the device is ready to start and proper
operation by an arrow under READY. The arrow under
STOP indicates that there is no start command (FWD or
REV)
●
The arrow in the bottom status line shows the actuation
via control signal terminals with the factory setting on I/O
Control (Control Input/Output). The arrow over FWD
(Forward) indicates the basic rotational direction (phase
sequence for a clockwise rotating field) on the output

Quickstart Wizard
The quick start assistant guides you in the quick
configuration through all important settings that have to be
made or that you should check for your application (see A in
figure on Page 62). The parameters that are called during the
process are listed in the table on Page 64, in the “Basic
(Standard Drive)” column.
The process is run from parameter to parameter. Returning is
not possible here.
In the quick configuration, the OK button activates
the individual parameter values and then moves on
OK
to the next parameter. Every parameter always
shows the value that is set in alternating sequence.
By actuating the OK button again, you activate the
value (value flashes).
The arrow buttons have restricted
functionality (change of parameter values
and cursor control) in the quick start
configuration.
Parameters
When the quick configuration is completed, the frequency
display M1.1 is activated automatically. Selecting the PAR
main menu again enables you to call up the parameters of
the quick configuration and then change them freely.
Besides the parameters of the quick configuration, system
parameters S1.1 to S4.3 are also shown after the first
setting.
P1.1 = 0 activates access to all parameters and the full
functionality of all buttons of the keypad (free parameter
definition, see B in the figure on Page 62).
This exits the quick configuration and the guided setup with
the quick start assistant.

The filter time constant can be used to filter out disturbance
with analog signals.
In the default setting the filter time constant is active with
0.1 seconds. The time value set here applies to 63% of the
maximum analog signal (+10V, 20 mA).
Long filter times lead to a delay in the analog signal
processing.
You can deactivate the filter time constant by setting the
