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.
