A
Functions and configuration
Summary
MR-J3-D05 has two systems in which the each system has SS1 function (delay time) and output of STO function.
Specifications
*1 Inrush current of approximately 1.5 A flows instantaneously when turning the control circuit power supply on. Select an appropriate
capacity of power supply considering the inrush current.
*2 Power-on duration of the safety logic unit is 100,000 times.
*3 _: in signal name indicates a number or axis name.
*4 For the test pulse input, contact your local sales office.
