5.3 A system configuration of the PROFINET
The following sketch is an example of PROFINET system configuration.
(1) When you wire the signal line to the PROFINET connection connector, take the connector off
WJ-PN and please wire it in the state that cut the communication power supply. WJ-PN may be
damaged by false contact.
(2) Network cables should be fixed without tension. Cables fixed under tension have the potential of
causing a communication fault by removing a connector.
(3) The communication line and the power line should wire the position that they separated as
much as possible. When the position of the power line is near the communication line, it may not
communicate by a noise.
(4) Ensure external emergency stop measures are taken to stop the inverter, in the event of a
network fault.
(a) Break the power supply of the Inverter when the network PROFINET IO controller detects a
communication fault.
(b) When the PROFINET IO controller detects a communication fault, turn on the intelligent input
terminal which would be allocated (FRS), (RS) and/or (EXT) function.
(c) Setting command P045 (Inverter action on communication error). Regarding this setting, the
inverter is tripped, deceleration or free run stop when it detects a communication fault by itself.
(Factory initialization of command P045 (Inverter action on communication error) is tripped.
e.g. WJ200 / WL200 becomes the trip when a PROFINET IO controller detects a
communication fault when WJ200 / WL200 runs by an order from the PROFINET.)
-About SAFETY-
When WJ200 / WL200 is used with Dip-Switch in the position to activate functional safety and
communication PROFINET IO controller unit detects the communication error, please turn “OFF (to
interrupt the output)” GS1 signal (intelligent input #3) and GS2 (intelligent i nput #4.) It is to be
noticed that approval by third party for “STO” function is void even if the safety function is activated
with Dip-Switch in the position to select functional safety (STO) when WJ-PN is attached to WJ200 /
WL200.
