Profibus Option Card allows Toshiba VF-S11
Inverter to act as Profibus DP- Slave on Profibus network. It
connects on a control PCB of VF-S11 Inverter using 24pin
connector and provides Profibus DP- Slave port [9 pin D Sub]
along with the standard serial communication port [8 Pin RJ45
for Option Unit], Contact Input (F, R), Analog Input (VIA) ,
24 VDC Power supply and CC [ 5 Pin Terminal Block]. It also
provides relay Output (FLA, FLB, FLC) that can be assigned as
fault output [3 Pin Terminal Block].
This Option Card communicates with the VF-S11
Inverter (Control Card) and fetches various parameters and
makes them available on Profibus DP- Slave port. Control
actions such as, RUN/STOP, Frequency Direction
(FORWARD/REVERSE), Frequency Command, Emergency Off, Reset
etc. can also be issued by Profibus master PLC or any Profibus
master Device to VF-S11 Inverter through Profibus Option Card.
If user connects Toshiba Option Unit (eg.
TYPE-FORM : RKP001Z-0) to standard serial communication port
[8 Pin RJ45] while Profibus slave port is active, Processor on
Option Card detects the Option Unit (Using CD line) and stop
Profibus communication and allows Option Unit to communicate
with the VFS11 Inverter. As soon as the Option unit is
removed, Profibus communication is restored again.
