Note 2)
Note 1)
Note 1) The 24V power supply is prepared by customer (The power consumption is approx. 0.3A.)
In the customer's system, do not ground the + side of 24V power supply prepared by customer for con
-
nect to the controller. (related with emergency stop and parallel input/output) If it connects with the
controller under the condition that the + side is grounded, it will lead to failure of controller.
Note 2) The cable for general purpose can be used to the network cable. However, use the twisted shield cable of
AWG#22(0.3mm
2
) or more.
