12 Festo P.BE-CMMS-FHPP-PB-SW-EN en 0708NH
2. Safety instructions for electric drives and controllers
Warning
The series-supplied motor holding brake or an external motorholding brake controlled by the drive controller alone is not
suitable for protecting human beings.
Vertical axes must be additionally secured against falling or
sliding down when the motor is switched off with e.g.
- mechanical locking of the vertical axis,
- external braking, safety catch or clamping devices or
- sufficient weight compensation of the axis.
Warning
The external or internal braking resistance is activated and can
carry a dangerous intermediate circuit voltage for up to approx.
5 minute after the motor controller has been switched off. Ths can
cause serious bodily injury or even death if it is touched.
Before carrying out maintenance work, make sure that the
power supply is switched off and locked and that the
intermediate circuit is discharged.
Switch the electrical equipment free of voltage via the main
switch and make sure that it cannot be switched on again.
Wait until the intermediate circuit is discharged after
- maintenance work and repairs
- cleaning
- long periods out of use.
Warning
Proceed carefully with mounting. Make sure that during mounting
as well as later during the operation of the drive that no drilling
shavings, metal dust or mounting parts (screws, nuts, pieces of
wire) can fall into the motor controller.
Make sure also that the external voltage supply of the controller
(24 V) is switched off.
The intermediate circuit or the mains voltage must always be
switched off before the 24 V controller supply is switched off.
Avoiding accidents, bodily injury and/or material damage:
Festo P.BE-CMMS-FHPP-PB-SW-EN en 0708NH 13
2. Safety instructions for electric drives and controllers
Warning
Other work in the vicinity of the machine must only be carried
out when the AC or DC supply is switched off and locked.
Switched-off final stage or switched-off controller enable are not
suitable locking conditions. In the event of a fault, this could lead
to unintentional movement of the drive.
Warning
Carry out commissioning with a free-running motor, in order to
avoid mechanical damage, e.g. due to incorrect direction of
rotation.
Warning
Electronic devices are never fail-proof.
The user is responsible for ensuring that his system is brought
into a safe state if the electric device fails.
Warning
DANGER!
The servo drive controller and in particular the braking resistance,
external or internal, can become very hot. This can cause serious
burning if the devices are touched.
Warning
Dangerous voltage
High electric voltage!
Danger of death or serious bodily injury due to electric shock!
2.4.3 Protection aganst touching electric components
This section concerns only devices and drive components with voltages over 50 V. It is
dangerous to touch components with voltages of more than 50 V, as this can cause an
electric shock. When electric devices are operated, certain components in these devices
are always under dangerous tension.
For operation the relevant DIN, VDE, EN und IEC regulations, as well as all national and
local safety and accident prevention regulations must always be observed. The system
manufacturer or the user is responsible for ensuring that these regulations are observed.

2. Safety instructions for electric drives and controllers
Warning
Before switching the device on, fit the covers and protective
screens so that the device cannot be touched.
For devices which are to be fitted in a control cabinet, make sure
that a housing is fitted so that the electric components cannot be
touched.
Regulation VGB4 must be observed.
Warning
Always connect the protective earth conductor of the electrical
equipment and the devices firmly to the supply network.
Due to the integrated network filter the leakage current is greater
than 3.5 mA.
Warning
Note the minimum copper cross section for the protective
conductor during the complete sequence in accordance with
standard EN 60617.
Warning
Before commissioning, also for brief measuring and test pur-
poses, always connect the protective conductor to all electric
devices or connect to an earth cable in accordance with the
connection diagram.
Otherwise, high voltages may occur on the housing. These could
cause an electric shock.
Warning
Do not touch the electrical connection points of the components
when the device is switched on.
Warning
Before touching electric components with voltages over 50 V,
disconnect the device from the mains or voltage source.
Protect the device against being switched on again.
Warning
During installation note the amount of intermediate circuit
voltage, especially with regard to insulation and protective
measures.
Make sure that the earthing, the cross section size of the conductor
and the corresponding short-circuit protection are correct.
Festo P.BE-CMMS-FHPP-PB-SW-EN en 0708NH 15
2. Safety instructions for electric drives and controllers
Warning
The device has an intermediate fast discharge circuit in accordance
with EN 60204, section 6.2.4. In certain device constellations, particularly where several motor controllers are switched parallel in
the intermediate circuit or with a non-connected braking resistance,
the fast discharge may not have any effect. The motor controllers
can stand under dangerous tension for up to 1 minute after being
switched off (capacitor residual charge).
Warning
DANGER!
High electric voltage due to incorrect connection.
Danger of bodily injury or death due to electric shock!
2.4.4 Protection by low voltage (PELV) against electric shock
Voltages from 5 to 50 V on the connections and terminals of the motor controller are
protective small voltages which can be touched without danger in accordance with the
following standards:
- International: IEC 60364-4-41
- European countries in the EU: EN 50178/1998, section 5.2.8.1
Devices, electrical components and cables may only be connected to connections and
terminals from 0 to 50 V, providing they have a protective low voltage (PELV = Protective
Extra Low Voltage).
Connect only voltages and current circuits which have reliable separation of dangerous
voltages.
Such separation is achieved e.g. with isolating transformers, reliable optocouplers or
battery operation separate from the mains network.
2.4.5 Protection from dangerous movements
Dangerous movements can be caused by incorrect control of connected motors. There are
various causes:
- Unsafe or faulty circuitry or cabling
- Faults in operating the components
- Faults in the measured value and signal generators
- Defective or non-EMC valid components
- Faults in the software in the higher-order control system
These faults can occur immediately after the device is switched on or after a certain period
of operation.
16 Festo P.BE-CMMS-FHPP-PB-SW-EN en 0708NH
2. Safety instructions for electric drives and controllers
Warning
DANGER!
Dangerous movements.
Danger of injury or death, serious bodily injury or material damage.
Warning
DANGER!
Surfaces of the device housing may be hot.
Danger of injury. Danger of burning.
Warning
Danger of burning.
Do not touch the surface of the housing in the vicinity of hot
sources.
After switching devices off, leave them for 10 minutes to cool
down before touching them.
If you touch hot parts of the device such as the housing which
contains the heat sink and resistors, you may burn yourself.
The monitoring functions in the drive components exclude to a large extent the possibility
of incorrect operation of the connected drives. WIth regard to the protection of human
beings, especially the danger of bodily injury and/or material damage, one must not rely
on these circumstances alone. Until the fitted monitoring functions become effective, you
must reckon with at least one incorrect drive movement, the extent of which depends on
the type of control and on the operating state.
For the above-mentioned reasons, the protection of human beings must be ensured with
the aid of monitoring systems or by measures which are of higher order than the system.
These measures are foreseen depending on the specific features of a danger and fault
analysis by the system manufacturer. The safety regulations applicable to the system must
be observed here as well. Undesired movements of the machine or other incorrect functions can occur as a result of switching off, avoiding or failing to activate safety devices.

Warning
PROFIBUS® cabling
Due to the possibly very high baud rates, we recommend also the
use of the standardized cable and plug connector. These are in
some cases provided with additional diagnostic possibilities and in
the event of a fault they facilitate the fast analysis of the field bus
hardware.
When setting up the PROFIBUS network, you must follow the advice
in the relevant literature or the folllowing information and
instructions in order to maintain a stable, faultless system. If the
cabling is not correct, faults may occur on the PROFIBUS which
cause the motor controller to switch off with a fault for safety
reasons.

3.3.2 Termination and bus terminating resistors
Each bus segment of a PROFIBUS network must be fitted with terminating resistors in
order to minimize cable reflexions and to set a defined rest potential on the cable. The bus
termination is made at the beginning and end of a bus segment.
The terminating resistors are already provided on most commercially-available PROFIBUS
plug connectors. The PROFIBUS-DP interface has its own terminating resistors for coupling
to buses without terminating resistors. These can be switched via the two DIP switches on
the module (both switches to ON).
I
n order that the terminating resistors can be switched off,
In order that th enetwork can be operated reliably, only one bus termination must be used,
internal (via DIP switch) or external.
both
switches must be set to OFF.
The external circuitry can also be set up discretely (see Fig. 3.5). The 5 V supply voltage
required for the externally switched terminating resistors is provided at the PROFIBUS plug
of the PROFIBUS-DP interface (see pin assignment in the Tab. 3.1).
Fig. 3.5: Bus termination
If the set baud rate is greater than 1.5 MBaud, plugs with integrated series inductance
(110 nH) must be used due to the capacitive load of the slave and the cable reflexion
thereby created.

4. Configuration of the PROFIBUS module
4. Configuration of the PROFIBUS module
Several steps are required in order to produce a functioning PROFIBUS module. Some of
these settings should or must be carried out before the PROFIBUS communication is
activated. This chapter provides an overview of the relevant steps. The exact procedure is
described in the following chapters in more detail.
When planning the PROFIBUS module, the user must make firm decisions. Only then
should the parametrizing of the field bus connection on both sides be made. We recommend that the parametrizing of the slave be undertaken first. Then the master should be
configured. With correct parametrizing the application is ready immediately without communication faults.
As some parameters are not effective until save and reset, we recommend the following
procedure.
1. Setting the bus address in the FCT program in the window Operation Parameters.
2. Parametrizing and commissioning with the FCT. Especially also the setting physical
units.
3. Configuration of the PROFIBUS master.
For correct functioning it is necesary to define the physical units of the processing data
transmitted via the field bus. These can be set via the FCT.
24 Festo P.BE-CMMS-FHPP-PB-SW-EN en 0708NH
4. Configuration of the PROFIBUS module
Please note that the PROFIBUS communication can only be activated when the parameter records have been saved and a Reset
has been carried out.
4.1 Setting the slave address
The inserted PROFIBUS module will be recognized automatically when the motor controller
is switched on.
Each device (PROFIBUS module) in the network must be assigned with a clear bus address.
The bus address is set in the FCT program in the window Operation Parameters.
Permitted bus addresses are 3 … 125.
Addresses cannot be assigned by the master (the service Set_Slave_Address is not
supported). Each address is only assigned once.
4.2 PROFIBUS communication
After configuration with subsequent download and saving, the PROFIBUS communication
will be actuated with a reset. Please note that the above mentioned parameters can only
be modified when the protocol is deactivated. All parameters are only valid when the
PROFIBUS communication is deactivated and then re-activated.

Tab. 4.1: PROFIBUS configuration
4.4 PROFIBUS slave configuration
This section provides an overview of the steps required by the slave for parametrization
and configuration. As some parameters are only effective after saving and reset, we
recommend that commissioning with the FCT without connection to the PROFIBUS be
carried out first.
Important processing data for position, velocity and acceleration are transferred in
physical units. These should be parametrized before starting communication because
they determine how the data are to be interpreted in the motor controller.

This section provides an overview of the steps required by the master for parametrization
and configuration. We recommend the following procedure:
1. Installing the GSD file
2. Slave address
3. Configuration of the input and output data
On the part of the master, the motor controller must be incorporated in the PROFIBUS.
First the GSD file is installed if this has not already been done. Finally, the address and the
input and output data for the slave must be configured.
In order to make commisssioning fast and simple, the abilities of the PROFIBUS interface
of the motor controller are described in an EDS file. By using a suitable configuration tool
you can configure a device within a network. The EDS is contained on the CD supplied with
the product. The latest version can be downloaded from our home page (www.festo.com Automation - Download Area - Download Software - Product group "Electric drives").

This is shown below as an example of incorporating under SIEMENS SIMATIC S7.
4.5.1 Configuration with SIMATIC manager
The software package SIMATIC Manager serves for project planning and commissioning in
conjunction with PROFIBUS masters from Siemens or compatible masters.
In order that the motor controller can be incorporated in the PROFIBUS network, it must be
selected in the hardware catalogue (HW Config) –SIMATIC…). The motor controller CMMP
can be found under "PROFIBUS-DP\Additional Field Devices \Drives\Festo").
1. Pull the station type "Festo CMMP" by drag and drop onto the PROFIBUS-DP master
system.
