When the drive is connected to the AC mains or connected on the DC terminals, the motor may start at any time, causing risk of
death, serious injury, and equipment or property damage.
Press [Off] on the control panel - if present - before configuring parameters.
Make sure that the drive cannnot be started by external switch, a fieldbus command, an input reference signal from the con-
trol panel, via remote operation using MyDrive®software tools, or after a cleared fault condition.
Disconnect the drive from all power sources whenever personal safety considerations make it necessary to avoid unintended
motor start.
Check that the drive, motor, and any driven equipment are in operational readiness.
DANGER
DISCHARGE TIME
The drive contains DC-link capacitors, which can remain charged even when the drive is not powered. High voltage can be
present even when the warning indicator lights are off.
Failure to wait the specified time after power has been removed before performing service or repair work could result in death or
serious injury.
Stop the motor.
Disconnect AC mains, permanent magnet type motors, and DC-link connections to other drives.
Wait for the capacitors to discharge fully before performing any service or repair work. The exact discharge time is shown on
the front cover of the drive.
Use a measuring device to make sure that there is no voltage, before opening the drive or performing any work on the ca-
bles.
WARNING
LEAKAGE CURRENT HAZARD
Leakage currents exceed 3.5 mA. Failure to ground the drive properly can result in death or serious injury.
Ensure that the minimum size of the ground conductor complies with the local safety regulations for high touch current
equipment.
WARNING
EQUIPMENT HAZARD
Contact with rotating shafts or electrical equipment can result in death or serious injury.
Ensure that only trained and qualified personnel perform installation, start-up, and maintenance.
Ensure that electrical work conforms to national and local electrical regulations.
Follow the procedures in this guide.
CAUTION
INTERNAL FAILURE HAZARD
An internal failure in the drive can result in serious injury when the drive is not properly closed.
Ensure that all safety covers are in place and securely fastened before applying power.

2 Product Overview
2.1 PROFINET Features and Technical Data
Fieldbus options for iC7 are integrated in the control board. Fieldbuses are enabled on communication interfaces X1 and X2 only.
Modbus TCP is offered as standard, and other protocols such as PROFINET RT can be selected in the configurator when ordering a
drive, or alternatively, they can be activated later by a proof-of-purchase token.

2.3 iC Speed Profile
The iC Speed profile is used with the iC7 series. iC Speed profile differs from the PROFIdrive profile, because it does not have a State
Machine. It is only controlled by the actual state 1/0 of the control bits, not the sequence in which they are manipulated.

2.4.3 PROFIdrive State Machine
In the PROFIdrive control profile, the control bits perform different functions:
0–3 perform the basic start-up and power-down functions.
4–10 perform application-oriented control.
12–15 can be configured for different purposes.
See Illustration 1 for the basic state transition diagram, where control bits 0–3 control the transitions and the corresponding status
bit indicates the actual state. The black dots indicate the priority of the control signals. Fewer dots indicate lower priority, and more
dots indicate higher priority.
The general state diagram is defined in the PROFIdrive standard.

Each of the selections in a signal module can comprise the following data types:
Boolean
Unsigned 8/16/32
Signed 8/16/32
Float 32
The buffer size adapts to the data type of the selected signals. If a Boolean type is mapped, only bit 0 is used in the chosen signal
address, and the remaining 7 bits are not used.
The actual interpretation of the value that is read or written depends on the data type and representation. For example, motor
current is a real-type 32-bit value that is represented as float, and publishing the motor current as an actual value does not need any
scaling and factoring.
2.5.1 Functional Extension Options
Each functional extension option is defined by its own PROFINET device model with a module and submodule(s).
Slot 1 contains the application and the subsequent slots contain the installed options. Each option supports a module access point
(MAP), and other submodules contain the process data.

The iC7 series communication interface has 2 Ethernet ports (X1 and X2) and an embedded switch with 2 Ethernet RJ45 connectors.
It has 1 MAC and IP address, and is considered a single device in the network. The communication interface supports 3 network
topologies:
Line topology
Star topology
Ring topology
2.6.1 Line Topology
In many applications, line topology enables simpler cabling and the use of fewer Ethernet switches. Observe network performance
and the number of devices in a line topology. Too many devices in a line may exceed network update time limits.

NOTICE
When line topology is used, take precautions to avoid timeout in the PLC when more than 8 drives are installed in series. Each
drive in the network adds a small delay to the communication due to the built-in Ethernet switch. When the update time is too
short, the delay can lead to a timeout in the PLC.
Set the update time as shown in the table. The numbers given are typical values and can vary from installation to installation.

NOTICE
Using tools such as MyDrive®Insight may influence system performance in a line topology.

NOTICE
Installing drives of different current ratings in line topology may result in unwanted power-off behavior.
Mount the drives with the longest discharge time first in the line topology. In normal operation, the drives with bigger cur-
rent ratings have a longer discharge time.
2.6.2 Star Topology
In a star network, all devices are connected to the same switch or switches. Star topology reduces the damage caused by single
cable failure. In a star topology, a single cable failure affects a single drive instead of all drives. In many applications, this topology
enables simpler cabling depending on the location and distance of the device.

2.6.3 Ring Topology
Ring topology enables the same simpler cabling and reduced cabling costs as line topology, but also reduces the damage caused
by a single cable failure in a similar manner as star topology.
NOTICE
When line topology is used, take precautions to avoid timeout in the PLC when more than 8 drives are installed in series. Each
drive in the network adds a small delay to the communication due to the built-in Ethernet switch. When the update time is too
short, the delay can lead to a timeout in the PLC.

The ring topology protocol depends on the protocol in use.
For PROFINET, the Media Redundancy Protocol (MRP) is used. The MRP is designed to react deterministically on a cable failure. One
of the nodes in the network has the role of Media Redundancy Manager (MRM), which observes and controls the ring topology to
react to network faults. Usually this device is a PLC or network switch.

3 Fieldbus Cable Connections
3.1 Prerequisites for Installation
Communication interfaces are integrated in the control board in iC7 drives.
The position of the connections differs based on the control board concept and frame, for example. For more information on the
location of the connections, cabling, and shielding, refer to the drive design guide.
3.1.1 Communication Interface X1/X2 in Frames FA02–FA12
The communication interface is on the top of the frequency converter as shown in Illustration 6. Industrial-grade RJ45 connectors
are recommended for optimal connection. A combined shield/fixing plate, the Fieldbus EMC plate, is available as an accessory to
strengthen the mechanical fixation of the cables.
