Safety Note

WARNING

HIGH VOLTAGE

The voltage of the frequency converter is dangerous
whenever connected to mains. Incorrect installation of the
motor, frequency converter, or fieldbus may damage the
equipment, cause serious personal injury, or death.
Consequently, the instructions in this manual, as well as
national and local rules and safety regulations, must be
complied with.

Safety Regulations

1. The frequency converter must be disconnected
from mains before carrying out repair work.
Check that the mains supply has been discon­nected and that the necessary time has passed
before removing motor and mains plugs.

2. The off-command on the serial bus does not
disconnect the equipment from mains and should
not be used as a safety switch.

3. Correct protective earthing or grounding of the
equipment must be established. The user must
be protected against supply voltage, and the
motor must be protected against overload in
accordance with applicable national and local
regulations.

4. The earth leakage currents are higher than 3.5
mA.

5. Do not remove the plugs for the motor and
mains supply while the frequency converter is
connected to mains. Check that the mains supply
has been disconnected and that the necessary
time has passed before removing motor and
mains plugs.

Warning against Unintended Start

1. The motor can be brought to a stop with bus
commands while the frequency converter is
connected to mains. If personal safety consider­ations make it necessary to ensure that no
unintended start occurs, these stop functions are
not sufficient.

2. While parameters are being changed, there is a
risk that motor starts.

2.1.5 Topology

The POWERLINK module features a built-in POWERLINK
slave controller and a two port HUB. This module enables
the possibility for connecting several POWERLINK options
in a line topology. If more than eight frequency converters
are connected in line, it will require special attention
towards the timing in the network.

It is important in a POWERLINK system, that the
connection is done correctly. POWERLINK is based on HUB

technology, which means that connecting a none
POWERLINK device (for example, personal computer) leads
to malfunction of the system.

NOTE

Do not connect any non-POWERLINK device to any free
port as this causes malfunction of the complete
POWERLINK network.

130BD147.10

Illustration 2.4 Line Topology

Take care that following design rules are followed

1. Do not connect any non POWERLINK device (for
example PC) to any free port as this will cause
malfunction of the complete POWERLINK
network.

2. In a line topology all frequency converters must
be powered, either by mains or by a 24 V DC
option cards, for the built-in POWERLINK slave
controller to work.

3. To achieve interference-free operation of the
Ethernet, observe the following EMC precautions.
The correct handling of the motor cable shield is
vital for the overall performance of the system. If
the rules are not followed it will lead to loss of
the control and malfunction of the system. The
Ethernet communication cable must be kept
away from motor and brake resistor cables to
avoid coupling of high frequency noise between
the cables. Normally, a minimum distance of 200
mm (8 inches) is sufficient, but maintaining the
greatest possible distance between the cables is

How to Install MCA 123 POWERLINK Operating Instructions

8 MG92C102 - VLT® is a registered Danfoss trademark

2

recommended, especially where cables run in
parallel, over long distances, or if drives with a
bigger power size is installed. More information
can be found in the norm IEC 61000-5-2:1997.

4. When crossing of cables is unavoidable, the
Ethernet cable must cross motor and brake
resistor cables at an angle of 90°.

5. Always observe relevant national and local
regulations, for example regarding protective
earth connection.

NOTE

In a line topology all frequency converters must be
powered, either by mains or by their 24 V DC option cards,
for the built-in POWERLINK slave controller to work.

2.1.6 EMC Precautions

To achieve interference-free operation of the Ethernet,
observe the following EMC precautions. Additional EMC
information is available in the VLT

®

AutomationDrive Design

Guide.

NOTE

The correct handling of the shield of the motor cable is
vital for the overall performance of the system. If the rules
are not followed it can lead to loss of the control and
malfunction of the system.

NOTE

Always observe relevant national and local regulations, for
example regarding protective earth connection.

The Ethernet communication cable must be kept away
from motor and brake resistor cables to avoid coupling of
high frequency noise between the cables. When crossing is
unavoidable, the Ethernet cable must cross motor and
brake resistor cables at an angle of 90°.

3 How to Configure

3.1.1 IP Settings

All IP-related parameters are located in parameter group
12-0* IP Settings: The parameters are all set to POWERLINK
standard values, so no setting is needed. In POWERLINK,
the 12-00 IP Address Assignment is fixed to the selection
"From node ID". The IP address does follow the setting in
12-60 Node ID, so that the IP address is 192.168.100.xxx,
where xxx is the node ID. For 12-02 Subnet Mask, this will
be fixed to 255.255.255.0 and can not be changed.

The POWERLINK option offers two ways of IP address
assignment via parameter or DIP switch.

3.1.2

Ethernet Link Parameters

Parameter group 12-1* Ethernet Link Parameters holds
Ethernet Link information:

12-10 Link Status
12-11 Link Duration
12-12 Auto Negotiation
12-13 Link Speed
12-14 Link Duplex

Each port has unique Ethernet Link Parameters.

12-10 Link Status displays Link or No Link according to the
status of the present port.

12-11 Link Duration displays the duration of the link on the
present port. If the link is broken, the counter is reset.

12-12 Auto Negotiation is a feature that enables two
connected Ethernet devices to choose common
transmission parameters, such as speed and duplex mode.
In POWERLINK this feature is fixed to OFF and can not be
changed.

12-13 Link Speed - displays the link speed for each port. If
no link is present, “None” is displayed. In POWERLINK this
feature is fixed to 100 MBaud and can not be changed.

12-14 Link Duplex - displays the duplex mode for each port.
In POWERLINK, the Link Duplex is fixed to half Duplex, and
cannot be changed.

3.2

Configure the Frequency Converter

3.2.1 VLT Parameters

Pay particular attention to the following parameters when
configuring the frequency converter with a fieldbus
interface.

•

0-40 [Hand on] Key on LCP. If the [Hand on] key
on the frequency converter is activated, control of
the frequency converter via the fieldbus interface
is disabled.

•

After an initial power up, the frequency converter
automatically detects whether a fieldbus option is
installed in slot A, and sets 8-02 Control Word
Source to [Option A]. Adding, changing, or
removing an option from an already commis­sioned frequency converter does not change
8-02 Control Word Source. However, it causes a
Trip Mode, and the frequency converter displays
an error.

•

8-10 Control Word Profile. Choose between the
Danfoss FC Profile and the DS 402 profile. The
change of 8-10 Control Word Profile will first be
active at the next powerup.

•

8-50 Coasting Select to 8-56 Preset Reference Select.
Selection of how to gate fieldbus control
commands with digital input command of the
control card.

NOTE

When 8-01 Control Site is set to [2] Control word only, the
settings in 8-50 Coasting Select to 8-56 Preset Reference
Select are overruled, and all act on Bus-control.

•

8-03 Control Word Timeout Time to 8-05 End-of­Timeout Function. The reaction in the event of a

bus time-out is set via these parameters.

3.3

Configure the POWERLINK Network

5 How to Control the Frequency Converter

5.1 PDO Communication

The VLT® AutomationDrive uses the following profiles:

•

Frequency converter profiles

•

CANopen DS 402 profile

For each of the two profiles there is a set of SDO objects
that is only accessible if the profile is activated in
8-10 Control Word Profile. The change will first be active at
the next power up. The PDO communication has to be
configured, where a subset of SDOs can be mapped into
PDOs for cyclic communication.

PDO communication is reserved for high speed cyclic
access to parameters for control and status of the
frequency converter. The PLC sends out process control
data, and the frequency converter responds with a PDO
containing process status data. In the Danfoss POWERLINK
interface both PDOs can be freely be configured.

Select the signals for transmission from the master to the
frequency converter via the PLCs configuration tool.

12-21 Process Data Config Write, 12-22 Process Data Config
Read and 12-23 Process Data Config Write Size will be set

from the PLC and can be used to control if the configu­ration has been sent correctly from the PLC.

The POWERLINK option has only one PDO available: PDO

23. The PDO 23 is flexible in size and is adjustable to fit all
needs (max. 10 PCDs). The selection is made in the master
configuration and is then automatically downloaded to the
frequency converter during the transition from Init to Pre­Op. No manual setting of PPO types in the frequency
converter is required.

5.2.3 Reference Handling

The reference handling in FC Series is an advanced
mechanism that sums up references from different sources.

For more information on reference handling, refer to the
FC Series Design Guide.

Illustration 5.2 Reference Handling

The reference, or speed set point (MRV, sent via
POWERLINK), is always transmitted to the frequency
converter in percentage format as integers represented in
hexadecimal (0-4000 hex).

Depending on the setting of 3-00 Reference Range the
reference and MAV are scaled accordingly:

Illustration 5.3 Scaling of MAV and Reference

NOTE

If 3-00 Reference Range is set to [0] Min - Max, a negative
reference is handled as 0%.

The speed limit settings are depending on 0-02 Motor

Speed Unit and can be set to RPM or Hz. If 0-02 Motor
Speed Unit is set to RPM: The speed limit parameters
4-11 Motor Speed Low Limit [RPM] and 4-13 Motor Speed
High Limit [RPM] limit the actual frequency converter

output. If 0-02 Motor Speed Unit set to Hz: The speed limit
parameters 4-12 Motor Speed Low Limit [Hz] and 4-14 Motor

Speed High Limit [Hz]

limit the actual frequency converter

output.

4-19 Max Output Frequency limits the maximum output and
can also influence the maximum speed of the motor.

For reference and MAV formats, see Table 5.3.

MRV/MAV Integer in hex Integer in decimal

100% 4000 16.384

5.2.5 Influence of the Digital Input
Terminals upon FC Control Mode

The influence of the digital input terminals upon control of
the frequency converter can be programmed in
8-50 Coasting Select to 8-56 Preset Reference Select.

NOTE

Note the 8-01 Control Site overrules the settings in
8-50 Coasting Select to 8-56 Preset Reference Select, and
terminal 37 Coasting Stop (safe) overrules any parameter.

Each digital input signal can be programmed to logic AND,
logic OR, or to have no relation to the corresponding bit in
the control word. This way, fieldbus only, fieldbus AND
Digital Input, or Ether Fieldbus OR Digital input terminal
can initiate a specific control command, that is stop/coast.

CAUTION

To control the frequency converter via POWERLINK, set
8-50 Coasting Select to either [1] Bus, or to [2] Logic AND.
Then set 8-01 Control Site to [0] Digital and ctrl.word or [2]
control word only.

5.3 Control Profile

The frequency converter can be controlled according to
the DS 402 profile, or the Danfoss FC profile. Select the
desired control profile in 8-10 Control Word Profile. The
choice of profile affects the control and status word only.
The change of 8-10 Control Word Profile will first be
activated at the next power up.

The desired control profile can also be controlled by object
6060 Modes of operation and readout by object 6061
Modes of operation display. Value -1 indicates frequency
converter profile. Value 2 indicates DS 402 Velocity mode.
If the frequency converter is run in DS 402 profile, the DS
402 profile must be selected (for example, by 8-10 Control
Word Profile or object 6060). The four process data Control
Word, Reference, Status Word and Main Actual Value will
the information in according the specification. Make sure
that the profile selected is also the profile used in the PLC.

6.3.1 2000h–5FFFh Vendor Specific Object
Area

The area 2000h to 5FFFh holds the indexes for accessing
the Danfoss frequency converter parameters. All
parameters in the frequency converter are linked to
indexes in this area. The first index available is index
2001h. This index is linked to the frequency converters
0-01 Language. The rest of the POWERLINK index follows
the same rule, where the frequency converters parameter
number plus 2000h gives the POWERLINK index. For
example, reading the running hours in 15-01 Running
Hours, is calculated by 2000h + parameter number in hex
number=2000h+5DD=index 25DDh. The XDD file only
contains a subset of the frequency converters parameters.
This subset has the indexes that are required for setting up
the PDO communication. All parameters can be read or
written via SDO communication from the PLC. Table 6.31
shows a few indexes and their mapping.

8.1 Example: Process Data with PDO 23

This example shows how to work with PDO 23, which
consists of Control Word/Status Word and Reference/Main
Actual Value. In the example the frequency converter is set

to FC profile in 8-10 Control Word Profile. The PDO contains
up to ten objects, which can be programmed to monitor
process signals.

Table 8.1 Example of FC Profile

The application requires monitoring of the motor torque
and digital input, so PCD 2 is set up to read the current
motor torque. PCD 3 is set up to monitor the state of an
external sensor via the process signal digital input. The
sensor is connected to digital input 18.

An external device is also controlled via control word bit
11 and the built-in relay of the frequency converter.
Reversing is permitted only when the reversing bit 15 in
the control word and the digital input 19 are set to high.

For safety reasons, the frequency converter stops the
motor if the POWERLINK cable is broken, the master has a
system failure, or the PLC is in stop mode.

9.1.6 Warning and Alarm Messages

There is a clear distinction between alarms and warnings.
When there is an alarm, the frequency converter enters a
fault condition. After the cause for the alarm has been
cleared, the master will have to acknowledge the alarm
message before the frequency converter can start
operating again. A warning, on the other hand, may come
when a warning condition appears, then disappear when
conditions return to normal, without interfering with the
process.

Warnings
A single bit within a warning word represents warnings
within the frequency converter. Bit status [0] False means
no warning, while bit status [1] True means warning. Any
bit change in the warning word is notified by a change of
bit 7 in the status word.

Alarms
Following an alarm message, the frequency converter
enters fault condition. When the fault has been removed
and the controller has acknowledged the alarm message
by setting bit 7 in the control word, the frequency
converter resumes operation. A single bit within an alarm
word represents alarms within the frequency converter. Bit
status [0] False means no fault, while bit status [1] True
means fault.
