1 1 PRE-OPERATION INSTRUCTIONS 1.1 Unpacki ng and P roduct Co nfirmation T ak e the plug-in option out of the package, check the product name, and confirm that the product is as you ordered and intact. This product is a plug-in option dedic ated for the FR-A 700 /A 701 serie s.
2 PRE-OPERATION INS TRUCTIONS 1 1.1.2 SERIAL number check When you are using FR-A7AP with an FR-A700 series inverter , c heck the SERIAL number on the FR - A700. The FR-A700 series inverters having the following SERIAL or later are compatible with FR-A7AP .
3 PRE-OPERATION IN STRUCTIONS 1.2 Par ts Front view Rear view Mounting hole Mounting hole Mounting hole Encoder specification selection switch (SW1) Used to change the specification of encoder (differential line driver/complementary). Switch for manufacturer setting (SW3) Do not change from initially- set status (1, 2:OFF ).
4 2 2 INSTALLA TION 2.1 Pre-i nstalla tion in stru ctions Make sure that the input power of the inverter is OFF . CAUTION With input po wer ON, do not install o r remove the plug -in option. Otherw ise, the inverter and plug-in op tion may be dam aged.
5 INSTALLATION 2.2 Install ation procedur e 1) Remove the inverter front cover. 2) Mount the hex-head screw for option mounting into the inve rter scr ew hole (on earth plate) (size 5.5mm, tightening torque 0.56N x m to 0.75N x m). 3) Securely fit the c onnector of the plug-in option to the inverter connector along the guides.
6 INSTALLATION 2 CAUTION • Only one type of option per inverter may be used. Whe n two or more options are mount ed, priority is in the order of in verter option conn ectors 1, 2 and 3. The opt ions having l ower pr iority are inoper ative. • When the inverter cannot recog nize tha t the option is mo unted due to improp er inst allation, etc.

9 INSTALLATION 2.4 Wirin g (1) Use twisted pair shield c ables (0.2mm 2 or larger) to connect the FR- A7AP and position detector. T o prote ct the cables f rom nois e, run the m away from any source of noi se (e.g. t he mai n circ uit and power vo ltage).
10 INSTALLATION 2 (2) Connection with the CNC (computerized numerical controller) When one position detector is shared between FR-A7AP and NC, its output signal should be c onnected as shown on the right. In this c ase, the wiring length between FR-A7AP and NC should be as short as possible, within 5m.
11 INSTALLATION (4) Loosen the terminal screw and insert the cable into the terminal. REMARKS Information on blade te rminals Introdu ced produ cts (as of Fe b. 2012) z Phoenix C ontact Co .,Ltd. Screw Size Tighte ning T orque Cable Size Screwd river M2 0.
12 INSTALLATION 2 (5) For wiring of the invert er which has one f ront cover , remove a hook of the fr ont cover and use a spac e bec ome avail able . For wiring of the inverter which has front covers 1 and 2 , use the space on the left side of the control circuit terminal block.
13 INSTALLATION 2.5 Encoder Cable * As the termin al block of the FR-A7AP is an insertion type, earth (groun d) cables need to be modified. (Ref er to page 1 1 .
