Danger to life due to live parts and other energy sources

Death or serious injury can result when live parts are touched.

• Only work on electrical devices when you are qualified for this job.

• Always observe the country-specific safety rules.

Generally, six steps apply when establishing safety:

1. Prepare for shutdown and notify all those who will be affected by the procedure.

2. Disconnect the machine from the supply.
– Switch off the machine.
– Wait until the discharge time specified on the warning labels has elapsed.
– Check that it really is in a no-voltage condition, from phase conductor to phase

conductor and phase conductor to protective conductor.
– Check whether the existing auxiliary supply circuits are de-energized.
– Ensure that the motors cannot move.

3. Identify all other hazardous energy sources, e.g. compressed air, hydraulic systems,
water.

4. Isolate or neutralize all hazardous energy sources, e.g. by closing switches, grounding
or short-circuiting or closing valves.

5. Secure the energy sources against switching on again.

6. Make sure that the machine is completely locked ... and that you have the right
machine.

After you have completed the work, restore the operational readiness in the inverse

Converter with Control Units CU230P-2; CU240B-2; CU240E-2

12 Getting Started, 11/2013, A5E32885834B AA

1.4

Residual risks of power drive systems

The control and drive components of a drive system are approved for industrial and
commercial use in industrial line supplies. Their use in public line supplies requires a
different configuration and/or additional measures.

These components may only be operated in closed housings or in higher-level control
cabinets with protective covers that are closed, and when all of the protective devices are
used.

These components may only be handled by qualified and trained technical personnel who
are knowledgeable and observe all of the safety instructions on the components and in the
associated technical user documentation.

When assessing the machine's risk in accordance with the respective local regulations (e.g.,
EC Machinery Directive), the machine manufacturer must take into account the following
residual risks emanating from the control and drive components of a drive system:

1. Unintentional movements of driven machine components during commissioning,
operation, maintenance, and repairs caused by, for example:

– Hardware defects and/or software errors in the sensors, controllers, actuators, and

connection technology

– Response times of the controller and drive

– Operating and/or ambient conditions outside of the specification

– Condensation / conductive contamination

– Parameterization, programming, cabling, and installation errors

– Use of radio devices / cellular phones in the immediate vicinity of the controller

– External influences / damage

2. In the event of a fault, exceptionally high temperatures, including an open fire, as well as
emissions of light, noise, particles, gases, etc. can occur inside and outside the inverter,
e.g.:

– Component malfunctions

– Software errors

– Operating and/or ambient conditions outside of the specification

– External influences / damage

Inverters of the Open Type / IP20 degree of protection must be installed in a metal control
cabinet (or protected by another equivalent measure) such that the contact with fire inside
and outside the inverter is not possible.

3. Hazardous shock voltages caused by, for example:

– Component malfunctions

– Influence of electrostatic charging

– Induction of voltages in moving motors

– Operating and/or ambient conditions outside of the specification

– Condensation / conductive contamination

– External influences / damage

4. Electrical, magnetic and electromagnetic fields generated in operation that can pose a

risk to people with a pacemaker, implants or metal replacement joints, etc. if they are too
close.

5. Release of environmental pollutants or emissions as a result of improper operation of the

system and/or failure to dispose of components safely and correctly.

Note

The components must be protected against conductive contamination (e.g. by installing them
in a control cabinet with degree of protection IP54 according to IEC 60529 or NEMA 12).

Assuming that conductive contamination at the installation site can definitely be excluded, a
lower

degree of cabinet protection may be permitted.

For more information about residual risks of the components in a drive system, see the
relevant sections in the technical user documentation.

Installing the Power Module

WARNING

Danger of death caused by high leakage currents when the external protective conductor is
interrupted

The inverter conducts high leakage currents > 3.5 mA via the protective conductor. When
the protective conductor is interrupted, touching live components can result in electric
shock, which can lead to death or serious injuries.

• Connect a protective conductor, which satisfies at least one of the following conditions,
to the inverter:

– The protective conductor is routed so that it is protected against mechanical damage.

Cables routed in control cabinets or enclosed machine enclosures are considered to
be adequately protected.

– The protective conductor routed as an individual conductor has a cross-section of

≥ 10 mm² Cu.
– In a multi-core cable the protective conductor has a cross-section of ≥ 2.5 mm² Cu.
– Two parallel protective conductors with the same cross-section are installed.
– The protective conductor corresponds to the local regulations for equipment with

increased leakage current.

NOTICE

Damage to the CU240E-2 PN and CU240E-2 PN-F Control Units in the event of a short­circuit of the 24 V output

It is possible that the Control Units are defective if the following conditions occur
simultaneously:

1. A short-circuit to the 24 V output occurs at terminal 9 when the converter is operating.

2. The ambient temperature is at the upper permitted limit.

3. You have connected an external 24 V supply to terminals 31 and 32 and the voltage at
terminal 31 is at the upper permitted limit.

In order to rule out damage to the Control Units, you have to prevent all three conditions
occurring simultaneously.

3.2.3

Selecting the pre-assignment for the terminal strip

The inputs and outputs of the frequency inverter and the fieldbus interface have specific
functions when set to the factory settings.

When you put the frequency inverter into operation, you can change the function of each of
its inputs and outputs and the setting of the fieldbus interface.

To make the setting process easier, the inverter has various predefined assignments
(macros).

Only the inputs and outputs whose functions change by selecting a specific assignment, are
shown on the following pages.

Procedure

To select one of the inverter's pre-assigned settings, proceed as follows:

1. Think about which of the input and output functions you are using in the application.

2. Find the I/O configuration (macro) that best suits your application.

3. Note the macro number of the corresponding default setting.

You must set this macro number when putting the frequency inverter into operation.

You have found the appropriate inverter pre-assignment.

Wiring the terminal strip

NOTICE

Damage to the inverter when using long signal cables

Using long cables at the inverter's digital inputs and 24 V power supply can lead to
overvoltage during switching operations. Overvoltages can damage the inverter.

• If you use cables of more than 30 m at the digital inputs and 24 V power supply, connect
an overvoltage protection element between the terminal and the associated reference
potential.
We recommend using the Weidmüller overvoltage protection terminal with designation
MCZ OVP TAZ DIODE 24VDC.

WARNING

Danger to life as a result of hazardous voltages when connecting an unsuitable power
supply

Death or serious injury can result when live parts are touched in the event of a fault.

• For all connections and terminals of the electronic modules, only use power supplies
with protective extra low voltage (PELV), Class 2.

Requirements

● Use suitable cables:

– Solid or flexible cables.

– Suitable cable cross-section: 0.5 mm² (21 AWG) to 1.5 mm² (16 AWG).

When completely connecting up the unit, we recommend cables with a cross-section
of 1 mm² (18 AWG).

● Do not use end sleeves.

● You have found an appropriate pre-assignment for the terminal strips, which you can now

use to wire the inverter.

See also Section Selecting the pre-assignment for the terminal strip (Page 33).

● You have the appropriate tools:

– Small screwdriver to open the spring-loaded terminals

– Tool for stripping the cables

Commissioning

Commissioning is carried out with the IOP using one of the "basic commissioning wizards
(Page 21)". If the IOP does not contain the actual frequency converter software, a message
is displayed "Update is required". You can find the required information on the Internet at
"http://support.automation.siemens.com/WW/view/de/67273266
(http://support.automation.siemens.com/WW/view/en/67273266)".

In the basic commissioning, select the control mode for the motor, enter the motor data and
define the pre-assignment of the frequency converter interfaces. You can find the
corresponding wiring in section "Selecting the pre-assignment for the terminal strip
(Page 33)".

Overview of the commissioning

● When commissioning with wizards, the first step is to RESET to the factory settings. This
ensures that the frequency converter is in a defined basic setting.

After the basic commissioning, the wizard that you selected guides you through
application-specific settings.

● Before the frequency converter accepts your commissioning data, you must check these
and confirm them. You do this using the last but one menu item OVERVIEW OF THE
SETTINGS. In this screen, scroll down to CONTINUE and acknowledge it with OK.

● The last step is the prompt SAVE or INTERRUPT WIZARD? Select SAVE!
Commissioning using the wizards has now been completed.

● You can subsequently change your converter settings (Section "The most important
parameters at a glance (Page 48)").

● Once you have completed commissioning, you should back up the settings of your
converter e.g. on the IOP, so that they are not lost if the converter develops a defect.

1) If the IOP Assistant does not offer this setting, after completing the basic commissioning, set parameter p1900 to a value
of 1 using the parameter menu.

Identifying motor data

Alarm A07991 is output for as long as the converter has still not identified the motor data.
You must switch on the motor (e.g. from the IOP) to identify the motor data. The frequency
converter switches-off the motor after the motor data identification has been completed.

CAUTION

Motor data identification for dangerous loads

Secure dangerous plant and system parts before starting the motor data identification, e.g.
by fencing off the dangerous location or lowering a suspended load to the floor.

You have completed the converter's basic commissioning.

4.2.2

Enable "Safe Torque Off" safety function

Requirements:

● Commission a CU240E-2 Control Unit.

● In the basic commissioning, you selected a setting for the interfaces in which two

terminals are reserved for a safety function.

The "Basic Safety" wizard guides you through the enabling of the "Safe Torque Off (Basic
Safety)" safety function in a maximum of 18 steps. Depending on the sources for "Safe
Torque Off", you can skip individual steps.

NOTICE

STO via terminal

If you implement the "Safe Torque Off" via digital inputs, DI4 and DI5 are brought together
to form a fail-safe digital input (FDI). You may not use these digital inputs for other
commands.
