1.1.2 Safety Note
The voltage of the frequency converter is dangerous whenever connected to mains. Incorrect installation of the motor, frequency
converter or fieldbus may cause damage to the equipment, 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.
1.1.3 Safety Regulations
1.
The frequency converter must be disconnected from mains if repair work is to be carried out. Check that the mains supply has been disconnected
and that the necessary time has passed before removing motor and mains plugs.
2.
The [OFF] key on the LCP of the frequency converter does not disconnect the equipment from mains and is thus not to be used as a safety
3.
Correct protective earthing or grounding of the equipment must be established, the user must be protected against supply voltage, and the
switch.
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.
Protection against motor overload is not included in the factory setting. If this function is desired, set par. to data value ETR trip or data value
ETR warning.
NB!
The function is initialised at 1.16 x rated motor current and rated motor frequency. For the North American market; the ETR functions
provide class 20 motor overload protection in accordance with NEC.
6.
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.
7.
Please note that the frequency converter has more voltage inputs than L1, L2 and L3, when load sharing (linking of DC intermediate circuit) and
external 24 V DC have been installed. Check that all voltage inputs have been disconnected and that the necessary time has passed before
commencing repair work.

1.1.4 Warning against Unintended Start
1.
The motor can be brought to a stop by means of digital commands, bus commands, references or a local stop, 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, the motor may start. Consequently, the [OFF] key must always be activated.
3.
A motor that has been stopped may start if faults occur in the electronics of the frequency converter, or if a temporary overload or a fault in
the supply mains or the motor connection ceases.
Touching the electrical parts may be fatal - even after the equipment has been disconnected from mains.
Also make sure that other voltage inputs have been disconnected, such as external 24 V DC, load sharing (linkage of DC intermediate circuit), as well as
the motor connection for kinetic back up.
Please take note of discharge times and further safety guidelines from the section: “Safety and conformity”, in the respective Design Guide (MG.33.Ax.yy).

3.1.4 Topology
The MCA 122 features a build-in Ethernet-switch, thus having two Ethernet RJ-45 connectors. This enables the possibility for connecting several Modbus
TCP options in a line topology as an alternative to the typical star-topology.
The two ports are equal, in the sense that they are transparent for the option. If only one connector is used, either port can be used.

NB!
Please observe that mounting drives of different power-sizes in a line topology may result in unwanted power-off behaviour.
Smaller drives discharge faster than bigger drives. This can result in loss of link in the line topology, which may lead to control word
timeout.
To avoid this, mount the drives with the longest discharge time first in the line topology.

3.1.5 Network
It is of high importance that the media chosen for Ethernet data transmission are suitable. Usually CAT 5e and 6 cables are recommended for industrial
applications. Both types of cable are available as Unshielded Twisted Pair and Shielded Twisted Pair. Generally shielded cables are recommended for use
in industrial environments and with frequency converters.
A maximum cable-length of 100 m is allowed between switches.
Optical fibres can be used for gapping longer distances and providing galvanic isolation.
For connecting Modbus TCP devices both hubs and switches can be used. It is, however, recommended always to use suitable industrial graded Ethernet
switches. For more information regarding IP-switching, please refer to section: IP Traffic in this manual.

3.1.6 Recommended Design Rules
While designing Ethernet networks special attention and caution must be taken regarding active network components.
While designing a network for line topology it is important to notice that a small delay is added with each every switch in the line.
It is not recommended to connect more than 32 drives in a line at any API. Exceeding the recommended design rules, may result in failing communication.

3.1.7 EMC Precautions
The following EMC precautions are recommended in order to achieve interference-free operation of the Ethernet network. Additional EMC information is
available in the FC 200/FC 300 series Design Guide.
NB!
Relevant national and local regulations, for example regarding protective earth connection, must be observed.
3
The Ethernet communication cable must be kept away from motor and brake resistor cables to avoid coupling of high frequency noise from one cable to
the other. Normally a distance of 200 mm (8 inches) is sufficient, but maintaining the greatest possible distance between the cables is recommended,
especially where cables run in parallel over long distances. When crossing is unavoidable, the Ethernet cable must cross motor and brake resistor cables
at an angle of 90 degrees.

Par. 12-10, Link Status will display Link or No Link according to the status of the present port.
Par. 12-11, Link Duration will display the duration of the link on the present port. If the link is broken the counter will be reset.
Par. 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 this process, the connected devices first share their capabilities as for these parameters and then choose the fastest transmission mode
they both support.
By default this function is enabled.
Incapability between the connected devices, may lead to decreased communication performance.
To prevent this, Auto Negotiation can be disabled.
If par. 12-12 is set to OFF, link speed and duplex mode can be configured manually in par. 12-13 and 12-14.
Par. 12-13, Link Speed – displays/sets the link speed per port. “None” is displayed if no link is present.
Par. 12-14, Link Duplex – displays/sets the duplex mode per port.
Half-duplex provides communication in both directions, but only in one direction at a time (not simultaneously).
Full-duplex allows communication in both directions, and unlike half-duplex, allows for this to happen simultaneously.

4.1.3 Configuring the Scanner
For configuring the scanner to communicate to the drive, no system (e.g. EDS, GSD file) file is needed. The FC100/200/300 is handled as a generic device
an as such, it has to be configured directly in the scanner. The following example setup the scanner to IP addresses 192.168.1.20 and the FC 302 to
address 192.168.1.20.
Configuring a Modicon scanner.
The following example uses the Unity Pro tool from Group Schneider to configure the PLC. The example only shows the setting up of the Protocol and
assigning I/O mapping to internal memory of the PLC.

4.1.4 IP traffic
The use of Ethernet based network for industrial automation purposes, calls for careful and thorough network design. Especially the use of active network
components like switches and routers requires detailed know-how about the behaviour of IP traffic.
Some important issues:
IGMP
IGMP (Internet Group Management Protocol) is an integrated part of IP. It allows hosts to join or leave a multicast host group. Group membership
information is exchanged between a specific host and the nearest multicast router.
Spanning Tree Protocol (STP)
For an Ethernet network to function properly, only one active path can exist between two nodes. Spanning-Tree Protocol is a link management protocol
4
that provides path redundancy while preventing undesirable loops in the network.
When loops occur, some switches see stations appear on both sides of it self. This condition confuses the forwarding algorithm and allows for duplicate
frames to be forwarded.
To provide path redundancy, Spanning-Tree Protocol defines a tree that spans all switches in an extended network. Spanning-Tree Protocol forces certain
redundant data paths into a standby (blocked) state. If one network segment in the Spanning-Tree Protocol becomes unreachable, or if Spanning-Tree
Protocol costs change, the spanning-tree algorithm reconfigures the spanning-tree topology and re-establishes the link by activating the standby path.
Spanning-Tree Protocol operation is necessary if the FC102/FC202/FC 300’s are running in a ring/redundant line topology.

and slave. When a message is sent from a master to a slave device, the function code tells the slave what kind of action to perform. When the slave
responds to the master, it uses the function code to indicate either a normal (error-free) response, or that some kind of error occurred (called an exception
response). For a normal response, the slave simply echoes the original function code. For an exception response, the slave returns a code that is equivalent
to the original function code with its most significant bit set to logic 1. In addition, the slave places a unique code into the data field of the response
message. This tells the master what kind of error occurred, or the reason for the exception. Please also refer to the section Function Codes Supported
by Modbus TCP and Exception Codes.
5.2.2 Data Field
The data field is constructed using sets of two hexadecimal digits, in the range of 00 to FF hexadecimal. These are made up of one TCP character. The
data field of messages sent from a master to slave device contains additional information which the slave must use to take the action defined by the
function code. This can include items such as coil or register addresses, the quantity of items to be handled, and the count of actual data bytes in the
field.

Explanation of the Control Bits
Bit 00, OFF 1/ON 1
Normal ramp stop using the ramp times of the actual selected ramp.
Bit 00 = "0" leads to the stop and activation of the output relay 1 or 2 if the output frequency is 0 Hz and if [Relay 123] has been selected in
par. 5-40 Function Relay.
When bit 00 = "1", the frequency converter is in State 1: “Switching on inhibited”.
Please refer to the PROFIdrive State Transition Diagram, at the end of this section.
Bit 01, OFF 2/ON 2
Coasting stop
When bit 01 = "0", a coasting stop and activation of the output relay 1 or 2 occurs if the output frequency is 0 Hz and if [Relay 123] has been selected
in par. 5-40 Function Relay.
When bit 01 = "1", the frequency converter is in State 1: “Switching on inhibited”. Please refer to the PROFIdrive State Transition Diagram, at the end
of this section.
Bit 02, OFF 3/ON 3
Quick stop using the ramp time of par. 3-81 Quick Stop Ramp Time. When bit 02 = "0", a quick stop and activation of the output relay 1 or 2 occurs if
the output frequency is 0 Hz and if [Relay 123] has been selected in par. 5-40 Function Relay.
When bit 02 = "1", the frequency converter is in State 1: “Switching on inhibited”.
Please refer to the PROFIdrive State Transition Diagram, at the end of this section.
Bit 03, Coasting/No coasting
Coasting stop Bit 03 = "0" leads to a stop. When bit 03 = "1", the frequency converter can start if the other start conditions are satisfied.

NB!
The selection in par. 8-50 Coasting Select Coasting select determines how bit 03 is linked with the corresponding function of the digital
inputs.
Bit 04, Quick stop/Ramp
Quick stop using the ramp time of par. 3-81 Quick Stop Ramp Time.
When bit 04 = "0", a quick stop occurs.
When bit 04 = "1", the frequency converter can start if the other start conditions are satisfied.
NB!
The selection in par. 8-51 Quick Stop Select determines how bit 04 is linked with the corresponding function of the digital inputs.
5
Bit 05, Hold frequency output/Use ramp
When bit 05 = "0", the current output frequency is being maintained even if the reference value is modified.
When bit 05 = "1", the frequency converter can perform its regulating function again; operation occurs according to the respective reference value.
Bit 06, Ramp stop/Start
Normal ramp stop using the ramp times of the actual ramp as selected. In addition, activation of the output relay 01 or 04 if the output frequency is 0
Hz if Relay 123 has been selected in par. 5-40 Function Relay. Bit 06 = "0" leads to a stop. When bit 06 = "1", the frequency converter can start if the
other start conditions are satisfied.
NB!
The selection in par. 8-53 Start Select determines how bit 06 is linked with the corresponding function of the digital inputs.
Bit 07, No function/Reset
Reset after switching off.
Acknowledges event in fault buffer.
When bit 07 = "0", no reset occurs.
When there is a slope change of bit 07 to "1", a reset occurs after switching off.
Bit 08, Jog 1 OFF/ON
Activation of the pre-programmed speed in par. 8-90 Bus Jog 1 Speed. JOG 1 is only possible if bit 04 = "0" and bit 00 - 03 = "1".
Bit 09, Jog 2 OFF/ON
Activation of the pre-programmed speed in par. 8-91 Bus Jog 2 Speed. JOG 2 is only possible if bit 04 = "0" and bit 00 - 03 = "1".
Bit 10, Data invalid/valid
Is used to tell the frequency converter whether the control word is to be used or ignored. Bit 10 = “0” causes the control word to be ignored, Bit 10 =
“1” causes the control word to be used. This function is relevant, because the control word is always contained in the telegram, regardless of which type
of telegram is used, i.e. it is possible to turn off the control word if you do not wish to use it in connection with updating or reading parameters.
Bit 11, No function/Slow down
Is used to reduce the speed reference value by the amount given in par. 3-12 Catch up/slow Down Value value. When bit 11 = "0", no modification of
the reference value occurs. When bit 11 = "1", the reference value is reduced.
Bit 12, No function/Catch up
Is used to increase the speed reference value by the amount given in par. 3-12 Catch up/slow Down Value.
When bit 12 = "0", no modification of the reference value occurs.
When bit 12 = "1", the reference value is increased.
If both - slowing down and accelerating - are activated (bit 11 and 12 = "1"), slowing down has priority, i.e. the speed reference value will be reduced.

Explanation of the Status Bits
Bit 00, Control not ready/ready
When bit 00 = "0", bit 00, 01 or 02 of the Control word is "0" (OFF 1, OFF 2 or OFF 3) - or the frequency converter is switched off (trip).
When bit 00 = "1", the frequency converter control is ready, but there is not necessarily power supply to the unit present (in the event of external 24 V
supply of the control system).
Bit 01, VLT not ready/ready
Same significance as bit 00, however, there is a supply of the power unit. The frequency converter is ready when it receives the necessary start signals.

Bit 02, Coasting/Enable
When bit 02 = "0", bit 00, 01 or 02 of the Control word is "0" (OFF 1, OFF 2 or OFF 3 or coasting) - or the frequency converter is switched off (trip).
When bit 02 = "1", bit 00, 01 or 02 of the Control word is "1"; the frequency converter has not tripped.
Bit 03, No error/Trip
When bit 03 = "0", no error condition of the frequency converter exists.
When bit 03 = "1", the frequency converter has tripped and requires a reset signal before it can start.
Bit 04, ON 2/OFF 2
When bit 01 of the Control word is "0", then bit 04 = "0".
When bit 01 of the Control word is "1", then bit 04 = "1".
Bit 05, ON 3/OFF 3
When bit 02 of the Control word is "0", then bit 05 = "0".
When bit 02 of the Control word is "1", then bit 05 = "1".
5
Bit 06, Start possible/Start not possible
If PROFIdrive has been selected in par.8-10 Control Word Profile, bit 06 will be "1" after a switch-off acknowledgement, after activation of OFF2 or OFF3,
and after switching on the mains voltage. Start not possible will be reset, with bit 00 of the Control word being set to "0" and bit 01, 02 and 10 being set
to "1".
Bit 07, No warning/Warning
Bit 07 = “0” means that there are no warnings.
Bit 07 = “1” means that a warning has occurred.
Bit 08, Speed ≠ reference / Speed = reference
When bit 08 = "0", the current speed of the motor deviates from the set speed reference value. This may occur, for example, when the speed is being
changed during start/stop through ramp up/down.
When bit 08 = "1", the current speed of the motor corresponds to the set speed reference value.
Bit 09, Local operation/Bus control
Bit 09 = "0" indicates that the frequency converter has been stopped by means of the stop button on the LCP, or that [Linked to hand] or [Local] has
been selected in par. 3-13 Reference Site.
When bit 09 = "1", the frequency converter can be controlled through the serial interface.
Bit 10, Out of frequency limit/Frequency limit OK
When bit 10 = "0", the output frequency is outside the limits set in par. 4-52 Warning Speed Low and par. 4-53 Warning Speed High. When bit 10 = "1",
the output frequency is within the indicated limits.
Bit 11, No operation/Operation
When bit 11 = "0", the motor does not turn.
When bit 11 = "1", the frequency converter has a start signal, or the output frequency is higher than 0 Hz.
Bit 12, Drive OK/Stopped, autostart
When bit 12 = "0", there is no temporary overloading of the inverter.
When bit 12 = "1", the inverter has stopped due to overloading. However, the frequency converter has not switched off (trip) and will start again after
the overloading has ended.
Bit 13, Voltage OK/Voltage exceeded
When bit 13 = "0", the voltage limits of the frequency converter are not exceeded.
When bit 13 = "1", the direct voltage in the intermediate circuit of the frequency converter is too low or too high.
Bit 14, Torque OK/Torque exceeded
When bit 14 = "0", the motor torque is below the limit selected in par. 4-16 Torque Limit Motor Mode and par. 4-17 Torque Limit Generator Mode. When
bit 14 = "1", the limit selected in par. 4-16 Torque Limit Motor Mode or par. 4-17 Torque Limit Generator Mode is exceeded.

Depending of the setting of par. 3-00 Reference Range, the reference is scaled from – Max. to + Max. or from Min. to Max.

The actual reference [Ref. %] in the VLT frequency converter depends on the settings in the following parameters:
Par. 1-23 Motor Frequency
Par. 1-25 Motor Nominal Speed
Par. 3-02 Minimum Reference
Par. 3-03 Maximum Reference
All references provided to the frequency converter are added to the total reference value. If a reference is to be controlled by the fieldbus only, ensure
that all other reference inputs are zero.
This means that digital and analogue input terminals should not be used for reference signals. The default setting (0%) should be maintained for preset
references in par. 3-10 Preset Reference.
NB!
If the bus speed reference is negative, and the control word contains a run reverse signal, the drive will run clockwise (- - is +).

Table 7.2: NS1 + NS2: Network Status (one per port)
Check: Link Status
The status of the Ethernet link cannot be directly identified by means of the LEDs.
Use par. 12-10, Link Status to verify presents of the link.
Use par. 12-11, Link Duration to verify that the link is steady present.
The parameter will show the duration of the present link, and preset to 00:00:00:00 if the link is broken.
Check: Cabling
In rare cases of cabling mis-configuration, the option might show the presents of a link, but no communication is running. Exchange the cable in doubt.
Check: IP Address
Verify that the option has a valid IP address (please refer to section: IP Settings) in par. 12-01, IP Address. If the option has identified a duplicate IP
Address NS LEDs will light steady red. If the option is set up for BOOTP or DHCP, verify that a BOOTP or DHCP server is connected in par. 12-04, DHCP
Server. If no server is connected, the parameter will show: 000.000.000.000.

7.1.2 Alarm Word and Warning Word
Alarm word and warning word are shown in the display in Hex format. If there is more than one warning or alarm, a sum of all warnings or alarms will
be shown. Warning word and alarm word are displayed in par. 16-90 to 16-95. For more information on the individual alarms and warnings, please refer
to: FC 200/FC 300 Design Guide.
NB!
Please note that the availability of the individual alarms and warnings are dependent on the drive type: /FC102/202/FC 300 series.
Warning and Alarm Messages
There is a clear distinction between alarms and warnings. In the event of an alarm, the frequency converter will enter a fault condition. After the cause
for the alarm has been cleared, the master must acknowledge the alarm message in order to start operation of the frequency converter again. A warning,
on the other hand, may appear when a warning condition arises, then disappear when conditions return to normal without interfering with the process.
Warnings
All warnings within the frequency converter are represented by a single bit within a warning word. A warning word is always an action parameter. Bit
status FALSE [0] means no warning, while bit status TRUE [1] means warning. Each bit status has a corresponding text string message. In addition to
the warning word message the master will also be notified via a change in the status word.
7
Alarms
Following an alarm message the frequency converter will enter a fault condition. Only after the fault has been rectified and the master has acknowledged
the alarm message by a bit in the Control Word, can the VLT resume operation. All alarms within the VLT are represented by a single bit within an alarm
word. An alarm word is always an action parameter. Bit status FALSE [0] means no alarm, while bit status TRUE [1] means alarm. In CIP, Alarms are
divided in to two categories:
-
Major Recoverable Faults
-
Major Unrecoverable Faults
Please refer to the following tables for a classification of the specific faults.
