Warnings
Cables must not be connected or disconnected, nor signal tests carried out, while the power is
switched on.
The Varispeed L7 DC bus capacitor remains charged even after the power has been switched off. To
avoid an electric shock hazard, disconnect the frequency inverter from the mains before carrying out
maintenance. Then wait for at least 5 minutes after all LEDs have gone out.
Do not perform a withstand voltage test on any part of the inverter. It contains semiconductors,
which are not designed for such high voltages.
Do not remove the digital operator while the mains supply is switched on. The printed circuit board
must also not be touched while the inverter is connected to the power.
Never connect general LC/RC interference suppression filters, capacitors or overvoltage protection devices to
the inverter input or output.
CAUTION
To avoid unnecessary over current faults, etc., being displayed, the signaling contacts of any contactor or switch fitted between inverter and motor must be integrated into the inverter control logic
(e.g. baseblock).
This is absolutely imperative!
This manual must be read thoroughly before connecting and operating the inverter. All safety precautions and instructions for use must be followed.
The inverter must be operated with the appropriate line filters, following the installation instructions
in this manual and with all covers closed and terminals covered.
Only then will adequate protection be provided. Please do not connect or operate any equipment
with visible damage or missing parts. The operating company is responsible for any injuries or
equipment damage resulting from failure to heed the warnings in this manual.
VII
Safety Precautions and Instructions
1. General
Please read these safety precautions and instructions for use thoroughly before installing and operating this
inverter. Also read all of the warning signs on the inverter and ensure they are never damaged or removed.
Live and hot inverter components may be accessible during operation. Removal of housing components, the
digital operator or terminal covers runs the risk of serious injuries or damage in the event of incorrect installation or operation. The fact that frequency inverters control rotating mechanical machine components can give
rise to other dangers.
The instructions in this manual must be followed. Installation, operation and maintenance may only be carried
out by qualified personnel. For the purposes of the safety precautions, qualified personnel are defined as individuals who are familiar with the installation, starting, operation and maintenance of frequency inverters and
have the proper qualifications for this work. Safe operation of these units is only possible if they are used
properly for their intended purpose.
The DC bus capacitors can remain live for about 5 minutes after the inverter is disconnected from the power. It
is therefore necessary to wait for this time before opening its covers. All of the main circuit terminals may still
carry dangerous voltages.
Children and other unauthorized persons must not be allowed access to these inverters.
Keep these Safety Precautions and Instructions for Use readily accessible and supply them to all persons with
any form of access to the inverters.
2. Intended Use
Frequency inverters are intended for installation in electrical systems or machines. The systems and machines
must be correspondent wiht the relevant directives and standards. Relevant guidelines like Low Voltage Directives , Machinery Directives , Emc Directives and other s are to be kept.
The Inverters may be put into operation, when the systems and machines in whitch they are inrested to the
guidelines and laws correspondent.
CE marking is carried out to EN 50178, using the line filters specified in this manual and following the appropriate installation instructions.
3. Transportation and storage
The instructions for transportation, storage and proper handling must be followed in accordance with the technical data.
4. Installation
Install and cool the inverters as specified in the documentation. The cooling air must flow in the specified
direction. The inverter may therefore only be operated in the specified position (e.g. upright). Maintain the
specified clearances. Protect the inverters against impermissible loads. Components must not be bent nor insulation clearances changed. To avoid damage being caused by static electricity, do not touch any electronic
components or contacts.
VIII
5. Electrical Connection
Carry out any work on live equipment in compliance with the national safety and accident prevention regulations. Carry out electrical installation in compliance with the relevant regulations. In particular, follow the
installation instructions ensuring electromagnetic compatibility (EMC), e.g. shielding, grounding, filter
arrangement and laying of cables. This also applies to equipment with the CE mark. It is the responsibility of
the manufacturer of the system or machine to ensure conformity with EMC limits.
Contact your supplier or Omron-Yaskawa Motion Control representative when using leakage current circuit
breaker in conjunction with frequency inverters.
In certain systems it may be necessary to use additional monitoring and safety devices in compliance with the
relevant safety and accident prevention regulations. The frequency inverter hardware must not be modified.
CAUTION
If a PM motor is turned by any external force, high voltage is generated in the windings.
• During wiring, maintenance or inspection make sure, that the motor is stopped and can not turn.
• If the inverter is turned off and the motor must be turned, make sure that motor and inverter output are
electrically disconnected.
6. Inverter Setup
This L7 inverter can drive induction motors as well as permanent magnet motors.
Always select the appropriate control mode:
• For induction motors use V/f, Open Loop Vector or Closed Loop Vector control (A1-01 = 0, 2 or 3).
• For permanent magnet motors use no other control mode than Closed Loop Vector for PM (A1-01 = 6).
A wrong control mode selection can damage the inverter and motor.
If a motor is exchanged or operated the first time, always set up the motor control relevant parameters using
the nameplate data or perform autotuning. Do not change the parameters recklessly. To ensure a safe operation
with PM motors always set the:
• correct motor data
• the PG open detection parameters
• the speed deviation detection parameters
• the over acceleration detection parameters
Wrong parameter settings can cause dangerous behavior or motor and inverter damage.
CAUTION
If a permanent magnet motor is used, the peak current capability of the motor should always be higher than
the maximum inverter output current in order to prevent a demagnetization of the motor.
Refer to page 4-2, Start Up for details about the correct start up procedure.
7. Notes
The Varispeed L7 frequency inverters are certified to CE, UL, and c-UL.

EMC Compatibility
1. Introduction
This manual was compiled to help system manufacturers using Omron-Yaskawa Motion Control frequency
inverters to design and install electrical switch gear. It also describes the measures necessary to comply with
the EMC Directive. The manual's installation and wiring instructions must therefore be followed.
Our products are tested by authorized bodies using the standards listed below.
EN 61800-3:2004
2. Measures to Ensure Conformity of Omron-Yaskawa Motion Control Frequency
inverters to the EMC Directive
Omron-Yaskawa Motion Control frequency inverters do not necessarily have to be installed in a switch cabinet.
It is not possible to give detailed instructions for all of the possible types of installation. This manual therefore
has to be limited to general guidelines.
All electrical equipment produces radio and line-borne interference at various frequencies. The cables pass
this on to the environment like an aerial.
Connecting an item of electrical equipment (e.g. drive) to a supply without a line filter can therefore allow HF
or LF interference to get into the mains.
The basic countermeasures are isolation of the wiring of control and power components, proper grounding and
shielding of cables.
A large contact area is necessary for low-impedance grounding of HF interference. The use of grounding
straps instead of cables is therefore definitely advisable.
Moreover, cable shields must be connected with purpose-made ground clips.
3. Laying Cables
Measures Against Line-Borne Interference:
Line filter and frequency inverter must be mounted on the same metal plate. Mount the two components as
close to each other as possible, with cables kept as short as possible.
Use a power cable with well-grounded shield. Use a shielded motor cable not exceeding 20 meters in length.
Arrange all grounds so as to maximize the area of the end of the lead in contact with the ground terminal (e.g.
metal plate).
Shielded Cable:
–Use a cable with braided shield.
–Ground the maximum possible area of the shield. It is advisable to ground the shield by connecting the cable
to the ground plate with metal clips (see following figure).
X
Ground clip
Ground plate
The grounding surfaces must be highly conductive bare metal. Remove any coats of varnish and paint.
–Ground the cable shields at both ends.
–Ground the motor of the machine.
Installation inverters and EMC filters
For an EMC rules compliant installation consider
the following points:
• Use a line filter.
• Use shielded motor cables.
• Mount the inverter and filter on a grounded con-
ductive plate.
• Remove any paint or dirt before mounting the
parts in order to reach the lowest possible
grounding impedance.

Controlling the Ambient Temperature
To enhance the reliability of operation, the Inverter should be installed in an environment free from extreme
temperature increases. If the Inverter is installed in an enclosed environment, such as a cabinet, use a cooling
fan or air conditioner to maintain the internal air temperature below 45°C.
Protecting the Inverter from Foreign Matter
Place a cover over the Inverter during installation to shield it from metal power produced by drilling.
Always remove the cover from the Inverter after the completion of the installation. Otherwise, ventilation will
be reduced, causing the Inverter to overheat.
