Switch Name Switch Name Description
a Termination resistor
selection switch
Termination resistor for the RS485
communication port.
WJ200 has a built-in 200Ω resistor
activated by a DIP switch.
b Safe stop function
selection switch
To enable the Safe stop function, set the
DIP switch ON.
Before operating switch, make sure that
the input power supply is off.
c EDM function
selection switch
To enable the EDM function, set the DIP
switch ON.
Before operating switch, make sure that
the input power supply is off.
