This installation guide provides information for quick replacement of a VLT® PROFINET MCA 120 interface in the VLT® AutomationDrive
FC 361.
The installation guide is intended for use by qualified personnel. Users are assumed to be familiar with the VLT® drive, with PROFINET
technology, and with the PC or PLC used as a master in the system.
Read the instructions before installation and ensure that instructions for safe installation are observed.
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 minimum waiting time is specified in table Discharge time and is also visible
-
on the nameplate on top of the drive.
Before performing any service or repair work, use an appropriate voltage measuring device to make sure that the capacitors
-
are fully discharged.

•Choose suitable media for Ethernet data transmission. CAT5e and CAT6 cables are recommended for industrial applications. Both
types are available as unshielded twisted pair and shielded twisted pair.
•Shielded cables are recommended for use in industrial environments and with drives.
•A maximum cable length of 100 m (328 ft) is allowed between the switches.
3.2 Cable Specifications
PROFINET cables used are based electrically on category 5 balanced LAN cables according to ISO/IEC 11801 Edition 2.0, Class D.
Type C cables can be used in special applications (for example, the use of trailing cables and frequently moved machine parts), even
though their design and mechanical parameters can deviate from the specifications of type A and type B cables. Still, most of the
electrical parameters (for example, impedance levels) are retained.
Highly flexible copper cables generally have the finest stranded conductors and a highly resistant polyurethane outer sheath. Various
outer sheath materials are permitted to meet the various demands regarding resistance of industrial environments and exterior/
underground laying (natural and synthetic oil, grease, coolants/lubricants, chemicals, high and low temperatures, UV radiation, and so
on).

1. Make sure that the power to the drive is disconnected.
2. Remove the front cover from the drive.
3. Remove the LCP (Local Control Panel) or blind cover, and then remove the LCP cradle from the drive.
4. Disconnect the communication cables from the existing MCA option card.
5. Remove the existing MCA option card from the drive.
6. Fit the new VLT® PROFINET MCA 120 option card into slot A. Mount the option with the Ethernet port facing up for top cable entry.
7. Connect the Ethernet cables. See
illustration 1 and table 4 for the definition of PROFINET connectors.

8. Set the address switches if needed.
9. Fit the LCP cradle.
10. Fit the LCP or blind cover in the LCP cradle.
11. Fit the front cover on the drive.
12. Connect power to the drive.
4.2 Setting Address Switches
The option has address switches that are used to set the station name (host name).
•When all switches are set to ON, or all are set to OFF, change the station name via 12-08 Host Name or via DCP command.
•In all other combinations, the address switches have priority over the parameter setting. The station name is set based on the value
in 15-40 FC Type, and a 3-digit number selected from the DIP settings.
