Fig.4 Example when using multiple FR-D740-EC inverters manufactured in August
2010 or later for the safety stop function
NOTE
•
For Europe model:
When using the safety stop function, do not connect the FR-D700 series manufactured in July 2010
or before together with the one manufactured in August 2010 or later. If connected together, the
safety stop function may not work properly.
When the FR-D700 series manufactured in July 2010 or before must be used together, connect an
electronic component (diode) to the inverter output shutoff signals (terminal S1 and S2).
•
For Japan model:
When using the safety stop function, do not connect the FR-D700 series manufactured in December
2010 or before together with the one manufactured in January 2011 or later. If connected together,
the safety stop function may not work properly.
When the FR-D700 series manufactured in December 2010 or before must be used together,
connect an electronic component (diode) to the inverter output shutoff signals (terminal S1 and S2).
Refer to page 7 for the specification of the diode.
•
Do not connect the FR-E700-SC/NF/NC (source logic) or the FR-D700-SC (source logic) together with
the FR-D700 (sink logic). If connected together, the safety stop function does not work properly.
