Chaining a PC to several drives
Chaining a PC connected through a control panel
￭
The PC connected to the FDPI-02 interface unit through a control panel is chained to
several drives the same way as the control panel.
1.
Install and connect the interface units, set the parameters of group 49 for the
drives, enable the panel bus networking, connect the chain cables and terminate
the bus. For the instructions, see section
drives (page
21).
2.
Connect the PC to the control panel. For the instructions, see section
a PC through a control
For a chaining example, see section
Connecting chains to the PC's USB port
￭
You can connect chained control panels to more than one USB ports of the same PC.
The number of the chains is limited only by the number of the PC's USB ports.
Note: For the chaining instructions, see section
drives (page
26). For a chaining example, see
USB port (page
30).
•
Each chain can contain maximum 32 drives.
•
Each chain must be terminated with the control panel on one end and with
termination switch S1 of FDPI-02 on the other end.
Chaining a PC connected to a commercial converter
￭
You can use the FDPI-02 interface unit for chaining a PC to several drives through a
commercial USB - RS-485 converter or Ethernet - RS-485 converter.
After connecting the first FDPI-02 interface unit to the drive's control unit and the
commercial converter to the interface unit, continue as follows:
1.
Install and connect the second interface unit to the second drive's control unit.
For instructions, see sections
and
Connecting the FDPI-02 to the control unit (page
2.
Before connecting the drive to a network, set the parameters of group 49 Panel
port communication for each drive manually using the control panel.
Note:
•
All devices connected to the network must have a unique node ID (Parameter
49.01 Node ID number). For networked drives, it is advisable to reserve ID 1
for spare/replacement drives. Start numbering from ID 2.
•
The baud rate has to be the same for all nodes on the bus (Parameter 49.03
Baud rate).
•
Set parameter 49.05 Communication loss action value as Last speed (2).
