4 Configuring the System
4.1 Preparing for Configuration
Context:
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
). 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
.
