4.4.2 SS1 (time- -controlled) with external stop
Caution
!
In order to achieve stop Category 1 according to EN 60204--1 using function "SS1
(time controlled) with external stop (SS1E)", the higher--level control must facilitate
a controlled shutdown at the same time.
Caution
!
During the delay time (p9652), for "SS1 (time--controlled) with external stop",
arbitrary axis motion caused by the position controller is possible.
Differences between "Safe Stop 1 with OFF3 and with external stop"
"SS1 with OFF3" and "SS1 with external stop" have the following differences:
S In order to activate "SS1 with external stop", additionally parameter p9653 must
be set = 1.
S When SS1 is selected, the drive is not braked along the OFF3 ramp, but after
the delay time has expired (p9652), only STO/SBC is automatically initiated.
