Introduction
1.4 Product Overview
1.4.1 Intended Use
This manual relates to the VLT® FCD 300 PROFIBUS Converter MCA 117.
The VLT® FCD 300 PROFIBUS Converter MCA 117 is intended for replacing a VLT® Decentral Drive FCD 300 or a VLT® Decentral Drive
FCM 300 with a VLT® Decentral Drive FCD 302 in a PROFIBUS network.
With this PROFIBUS converter option, the FCD 302 reacts as an FCD 300 or an FCM 300 on the PROFIBUS network. Changes to PLC
programming or configuration are normally not necessary.
The FCD 302 identifies itself either as an FCD 300 or an FCM 300 on the PROFIBUS network. A write command to, for example, ramp-up
time in FCD 300 is automatically linked to the corresponding ramp-up time parameter in the VLT® Decentral Drive FCD 302.
NOTICE
Some parameters in the FCD 300 and FCM 300 are not supported in the FCD 302, and some parameters cannot be accessed via
the VLT® FCD 300 PROFIBUS Converter MCA 117. Refer to 5 Parameter Mapping Lists for more information. If a write request is
attempted to a parameter selection which is not supported, the drive discards the value and issues a positive reply. Only
parameters and functions described in this manual are supported.
NOTICE
The replacement drive must match the power size or be bigger than the replaced FCD 300 or FCM 300. Make sure that the
brake chopper matches the new drive. Make sure that the new drive meets the local regulations concerning the Machinery
Directive, pre-fuses, and other appropriate regulations.
NOTICE
Observe local rules and regulations when replacing a drive in an existing installation.
•The VLT® Decentral Drive FCD 302 reacts faster on most commands as the VLT® Decentral Drive FCD 300/FCM 300, which can
influence the applications. When replacing a VLT® Decentral Drive FCD 300/FCM 300 with the VLT® FCD 300 PROFIBUS Converter
MCA 117, the installer must ensure that the functionality is maintained. Due to the different timing, it may be necessary to
reprogram the controller, where signals from the drives react faster.
•The motor control algorithm of the VLT® Decentral Drive FCD 302 results in a better motor performance compared to FCD 300/FCM
300.
NOTICE
FACTORY SETTING OF PARAMETERS
After initialization of the FCD 302, most parameters are set to match the factory settings of the FCD 300/FCM 300 parameters.

2.3 Safety Precautions
WARNING
HIGH VOLTAGE
AC drives contain high voltage when connected to AC mains input, DC supply, or load sharing. Failure to perform installation,
start-up, and maintenance by qualified personnel can result in death or serious injury.
Only qualified personnel must perform installation, start-up, and maintenance.
When the drive is connected to the AC mains, the motor may start at any time, causing risk of death, serious injury, and
equipment or property damage. The motor may start by activation of an external switch, a fieldbus command, an input
reference signal from the LCP or LOP, via remote operation using MCT 10 Set-up software, or after a cleared fault condition.
Press [Off] on the LCP before programming parameters.
-
Disconnect the drive from the mains 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.
-
WARNING
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 remote DC-link supplies, including battery back-ups, UPS, and
-
DC-link connections to other drives.
Wait for the capacitors to discharge fully. The time for full discharge of the capacitors is minimum 4 minutes for VLT®
-
Decentral Drive FCD 302, 400 V AC, 0.37–3.0 kW (0.5–4.0 hp).
Before performing any service or repair work, use an appropriate voltage measuring device to make sure that the capacitors

The VLT® FCD 300 PROFIBUS Converter MCA 117 changes the functionality of a VLT® Decentral Drive FCD 302 so that it can be used as a
spare part for a VLT® Decentral Drive FCD 300 or a VLT® DriveMotor FCM 300.
A VLT® Decentral Drive FCD 302 (0.37–2.2 kW (0.5–3.0 hp)) with flat bracket and adapter brackets (order number 134B6775) can be
mounted using the same drilling holes as for the FCD 300.
For a 3.0 kW (4.0 hp) FCD 302, mounting with adapter brackets is not possible. Thus, new holes must be drilled to mount the drive.
The FCD 302 cannot be used as a direct replacement of the VLT® Decentral Drive FCM 300 electronic part. For reuse of the existing
electric motor, a terminal box has to be fitted to the motor, and a motor cable has to be used as connection between the motor and
the FCD 302. Observe local regulations when changing the installation.
Initial power-up
The VLT® FCD 300 PROFIBUS Converter MCA 117sets the parameters of the VLT® Decentral Drive FCD 302 to FCD 300 defaults in 3
cases:
•At first time power up.
•When the drive has been set to initialize via parameter 14-22 Operation Mode.
•When a 3-finger reset is performed from the LCP at power-up.
This gives a short commissioning time and improves the backwards compatibility.
The MCA 117 also changes the default settings of the I/Os of the FCD 302 to match those of the FCD 300.
3.2 Electrical Installation
For electrical installation, local regulations might require further updates. This could be the case where the installation must be
updated to fulfill newer standards when machines are updated, or if local regulations have changed since the original decentral drives
were installed.
The following sections contain illustrations showing the old terminal number and their equivalents in the new drive. If a box in a
drawing is empty, there is no equivalent in the VLT® Decentral Drive FCD 302. In most cases, it is possible to program the FCD 302 to
deliver the same function on 1 of the terminals. If there are no boxes at all in an illustration, the drive has no terminal. For example, the
VLT® DriveMotor FCM 300 has a limited number of I/Os compared to the FCD 300.
3.2.1 Supply and Motor Terminals
Power cable terminals are 1:1 compatible between VLT® Decentral Drive FCD 300/VLT® DriveMotor FCM 300 and the VLT® Decentral
Drive FCD 302. If shielded cables are used, ensure that the shield is mounted as stated in the VLT® Decentral Drive FCD 302 Operating
Guide.
Motor terminals are 1:1 compatible between FCD 300 and FCD 302. If shielded cables are used, ensure that the shield is mounted as
stated in the VLT® Decentral Drive FCD 302 Operating Guide.
Illustration 2: Motor Cable Connections
Mechanical brake cable terminals are 1:1 compatible between the FCD 300 EB versions and the FCD 302 with brake chopper and
mechanical brake supply. If shielded cables are used, ensure that the shield is mounted as stated in the VLT® Decentral Drive FCD 302
Operating Guide. To enable this functionality, the VLT® FCD 300 PROFIBUS Converter MCA 117 sets parameter 5-40 [1] Function Relay to
[32] Mech Brake Ctrl. In the FCD 302, it is not possible to enable mechanical brake control and use relay 2 for another purpose.
Brake resistor cable terminals are 1:1 compatible between the FCD 300 EB versions and the FCD 302. If shielded cables are used, ensure
that the shield is mounted as stated in the VLT® Decentral Drive FCD 302 Operating Guide.
Illustration 4: Brake Resistor Cable Connections
The FCD 300 has dedicated connectors 31A and 31B for connection of the motor thermistors. The FCD 302 with MCA 117 installed uses
AI54 as motor thermistor connector. The FCD 302 can also use 1 of the digital inputs as thermistor source, but if multiple sensors are
connected in series, it might cause false alarms/warnings. The motor thermistor configuration is done via parameter 1-90 Motor ThermalProtection and parameter 1-93 Thermistor Resource.
Illustration 5: Motor Thermistor Cable Connection
The 24 V external supply cable terminals are 1:1 compatible between FCD 300 EB versions and the FCD 302. The FCD 302 may draw a
higher current from the 24 V supply. The FCD 300 has a power consumption of 12 W, where the FCD 302 consumes up to 50 W. The
consumption depends on the configuration of the I/O modules and the sensors connected to the drive.
Illustration 6: External 24 V Cable Connection
3.2.2 Control Signal Connectors
Digital input cable connection
Digital input terminals are 1:1 compatible between the VLT® Decentral Drive FCD 300 and the VLT® Decentral Drive FCD 302. If shielded
cable is used, ensure that the shield is mounted as stated in the VLT® Decentral Drive FCD 302 Operating Guide.
The FCD 300 reads the digital inputs every 12 ms whereas the FCD 302 reads the digital inputs every 1 ms.
The digital inputs of the FCD 300 are converted fully to the I/Os of the FCD 302. Terminal 3 of the VLT® DriveMotor FCM 300 is not
converted to a corresponding terminal in FCD 302. To support terminal 3 in FCM 300, configure the FCD 302 manually.
Illustration 7: Digital Input Cable Connections
Digital output cable connections
The FCD 300 has 1 dedicated digital output, which is terminal 46. This terminal is not converted to an existing FCD 302 output.
In FCM 300, terminal 9 could be used as either analog or digital output. To obtain the same functionality in FCD 302, configure an
analog or digital output manually.
Illustration 8: Digital Output Cable Connections
Analog I/O cable connections
The analog I/Os of the FCD 302 can be configured to cover most use cases. The default conversion from FCD 300 has a limitation as
there is no input 60 in the FCD 302. If analog input 54 in the FCD 302 is not used for motor thermistor, this input can be configured to
provide the functionality of output 60 in the FCD 300.
The 0–10 V analog input 53 of the FCD 300 is converted into the FCD 302 analog input 53. The analog input 53 of the FCD 302 can be
set to 0–10 V or 0–20 mA via switch S201. From factory, the switch is set in OFF position, which sets the analog input to 0–10 V.
Relay cable connections
The relays of the FCD 302 are compatible to the relays in FCD 300.
NOTICE
The relay in FCM 300 is rated to a resistive load of 5 A, 250 V AC, whereas the relay in FCD 302 is rated to a load of 2 A, 240 V AC.
Illustration 10: Relay Cable Connections
PROFIBUS cable connections
The PROFIBUS terminals of the FCD 300/FCM 300 are all converted to the PROFIBUS terminals of the FCD 302. The compensation coils
activated by the switches S101 to S104 of the FCD 300 are not needed in the FCD 302 PROFIBUS interface. The Termination of the
PROFIBUS line is done via the PROFIBUS termination switch.
To achieve interference-free operation of the PROFIBUS, install the VLT® Decentral Drive FCD 302 and the cables as described in the
VLT® Decentral Drive FCD 302 Design Guide: When routing the PROFIBUS cable:
•maintain high distance (minimum 200 mm (8 in)) between the PROFIBUS communication cable and the motor and brake resistor
cables to avoid coupling of high-frequency noise from one cable to another.
•ensure that, when crossing is unavoidable, the PROFIBUS cable crosses the motor and brake resistor cables at an angle of 90° .
For installation on machines where the FCD 302 has poor electrical contact to the machine due to paint or high ohmic surface, a special
stainless steel plug and bracket exist. The order number is 175N2598.
This plug can be mounted in 1 of the unused cable entry holes and the supplied bracket has to be mounted to the plug and to the
metal construction of the machine. This ensures a low ohmic path for high-frequency noise that otherwise would have been added to
the shield of the PROFIBUS cable, causing disturbance of the communication.
NOTICE
Observe relevant national and local regulations, for example, regarding protective-earth connection.
All PROFIBUS stations connected to the same bus network must have a unique station address.
Prerequisites:
Before replacing an FCD 300 or FCM 300 by a VLT® Decentral Drive FCD 302 with VLT® FCD 300 PROFIBUS Converter MCA 117,
configure the station address in the FCD 302. Also, check that the FCD 302 detects which type of drive it has to replace.
Procedure
1. Set the PROFIBUS address of the VLT® Decentral Drive FCD 302 to the same address as the drive that has to be replaced.
2. Set parameter 8-02 Control Word Source to [3] Option A.
3. Cycle power (400 V AC and 24 V DC back-up if applied) to the FCD 302.
The MCA 117 probes for the different FCD300/FCM300 Ident numbers. While probing, the drive flashes the ST/MS LED (see
4.5 LED Behavior). When the matching Ident number used by the master is detected, the VLT® Decentral Drive FCD 302
locks the ident number to the option, and sets the parameters of the FCD 302 to match the functionality of the old drive.
The master/PLC now recognizes the FCD 302 as an FCD 300 or FCM 300.
4.2 PROFIBUS Address Set via Hardware Switches
WARNING
SHOCK HAZARD
Working with the hardware switches while the power supply is still on may cause personal injuries.
Switch off the power supply before changing the hardware switches.
-
NOTICE
The address change comes into effect at the next power-up and can be read in parameter 9-18 Node Address.
4.3 PROFIBUS Address Set via Parameter or SSA Command
If all hardware switches are set to ON or OFF (factory switch setting), the PROFIBUS address can be set via parameter 9-18 Node Address
or the PROFIBUS SSA command. The address becomes valid after the next power cycle.
4.4 Commissioning
Prerequisites:
The station address of the VLT® Decentral Drive FCD 302 must be the same as for VLT® Decentral Drive FCD 300.
Procedure
1. Cycle power to the FCD 302.
The master/PLC now recognizes FCD 302 as an FCD 300.
Example:
A solid green NS LED on the VLT® FCD 300 PROFIBUS Converter MCA 117 indicates that communication between master and slave is
established.
If the NS LED flashes, the master/PLC has not recognized the FCD 302.
For more information, refer to 6.1 Troubleshooting Hints.
The LED flash patterns of the VLT® FCD 300 PROFIBUS Converter MCA 117 are not compatible with the patterns of the FCD
300/FCM 300 PROFIBUS LEDs.
4.6 Factory Settings
The VLT® FCD 300 PROFIBUS Converter MCA 117 is delivered from factory with the optimal settings to replace a VLT® Decentral Drive
FCD 300. If the VLT® FCD 300 PROFIBUS Converter MCA 117 is moved from one application to another, it is recommend to initialize the
drive. This initialization activates the factory settings and re-invoke of the Ident number detection. If the drive has been delivered from
factory with the option installed, initialization can be skipped.
Do the initialization via:
•Parameter 14-22 Operation Mode, or
•Three-finger reset by removing power to the drive, pressing [Status], [Main Menu], and [OK], and applying 400 V AC or 24 V DC
back-up power to the drive.
The MCA 117 sets the parameters of the FCD 302 so that the FCD 302/MCA 117 emulate the FCD 300 in the best way.
The parameters of the VLT® Decentral Drive FCD 302 are set to factory values and some FCD 302 parameters are set to values that
match the initial values of VLT® Decentral Drive FCD 300.
Factory copy via the FCD 300 parameter 006 Setup Copy is supported and initializes the FCD 302 and sets it to the FCD 300 default
settings.
