*1.While safety standstill detection outputs are in the ON state, the following pulse signal is output continuously for output circuit diagnosis.
When using the safety standstill detection outputs as input signals to control devices (i.e. Programmable Controllers), consider the pulse signal shown below.
*2.The following derating is required when Units are mounted side-by-side.
