NOTE
•
Pr.190 (RUN terminal function selection) must be set to "81". This setting makes the RUN output to
turn off in case of failure.
•
Do not connect the FR-D700 (sink logic) together with the FR-D700-SC (source logic). If connected
together, the safety stop function does not work properly. (Refer to page 7.)
