PD-01 PROFIBUS-DP Module
If the connection of PD-01 to VFD drives does not conform the table listed in page 2, users need to provide external 15VDC supply the power to PD-01 (not through the communication cable). Refer to the pin assignment of RJ11, it is allowed to supply power to PD-01 via RJ11.
PD-01 is energized while the power is applied to the VFD series Drives, then the SP LED will be steady green.
Removing the PD-01
To remove the PD-01, users shall:
Remove the connection cable between PD-01 and VFD series Drives.
Loose the PD-01 screws and remove DP connector from PD-01.
Pull down on the retaining clip and pull out the PD-01 from DIN rail gently.
Pin assignment of PROFIBUS-DP interface (DB9)
Use PROFIBUS-DP interface (DB9) of PD-01 connecting PD-01 to PROFIBUS DP system. The terminals are short-circuit-proof and isolated.

Terminator
Bus terminator is important when connects PD-01 to PROFIBUS-DP system. This terminator can be switched in and out via switches when the recommended bus connectors have been used.
If extended 4-PIN socket for the connection is used, user may use the internal terminator provided by PD-01 via setting the switch. If the switch is turned to "S" (Short), the internal terminator is disabled, then A1 and A2, B1 and B2 are all normally close. If the switch is turned to "R" (Resistor), the internal terminator between A1 and B1 is enabled, but A2 and B2 are disconnected from bus.
