Technical information
Two LEDs on PD-01 used to display the connection status of PD-01:
SP LED: indicating the connection status between PD-01 and VFD series Drives
NET LED: indicating the connection status between PD-01 and PROFIBUS-DP
% For more information of LEDs display, refer to Chapter 6. Troubleshooting.
The address in PROFIBUS-DP can be set via two rotary address switches, ADDH
and ADDL, on PD-01:
ADDH used as a high 4 bits of address, ADDL used as a low 4 bits of address.
% For more information of address switches, refer to Chapter 4. Communication.
A specific 6-PIN communication cable for RJ11, is used to connect the PD-01 to
VFD series Drives via RS-485 interface. VFD series Drives supply the 15V DC
power to PD-01 through this cable.
PROFIBUS-DP interface (DB9) uses a standard PROFIBUS-DP system interface.
We recommend users use the standard connector to connect PD-01 to
PROFIBUS-DP system. Besides, the PD-01 also provides a 4-PIN extended socket
for users to connect it to PROFIBUS-DP system based upon the requirements.
However, please pay attention to the assignment of A1, B1, and A2, B2 on the
4-PIN extended socket.
PD-01 supports baud rates of 9.6kbaud to 12Mbaud.
Functionality
Cyclical process data exchange (PZD).
Parameter accessing: cyclical accessing of parameters (PKW).
PROFIBUS supports the control commands SYNC and FREEZE for data
synchronization between master and slaves.
Support the configuration of data structure for data exchange with VFD series
Drives.
