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.
