Connection of DOG and STOP Inputs
and Handling of Limit Switchesfor
Limit Detection
Various limit switch inputs areconnected to theDOG
input and theSTOP input in accordancewith the
operation mode.
The polarity of these limit switch inputs is inverted by the
state of the BFM #3 b12 and b14. (Refer to 5.2)
Connection examples are shown below.
➀
Home position return operation mode
(BFM #25 b6 = 0
→
1)
➁
Interrupt single-speed operation mode
(BFM #25 b9 = 0
→
1)
➂
External command operation mode
(BFM #25 b11 = 0
→
1)
< When normally open contactsare used >
The input connection diagram shown below indicates
thecasewheretheBFM #3 b 12 and b14 areset to 0
and normally open contacts (a-contacts) are used.
Input switches SW1 to SW3 are selected in accordance
with thetypeof operation.
