NOTICE
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.
