9.1.6.1. Output Signal Format
l
The output signal format --- either IPOS format or FIN format --- can be selected by setting the
FW parameter.
à
FW data : FIN format is selected when data
¹
0 (shipping set : FW1)
à
FW0
: IPOS format
(1) When data of parameter “FW” is not “0” (Zero) (FIN format)
l
“IPOS” output indicates that the positioning has completed.
l
IPOS will be output for every positioning start command such as RUN and HOS .
l
Out put format
à
IPOS output is always open and it closes only for the moment set by “FW” when
completion of positioning. (Closing time unit in “FW” is 100m sec. Shipping set FW1 :
100m sec.)
l
Recommendation
We recommend to use FIN format when you use the programmable indexer in the
Driver Unit.
l
“IPOS” will not be output for pulse train operation and jogging operation.
l
When the positioning is stopped in the middle of operation by the emergency stop or overtravel
limit, “IPOS” will not be output.
(2) When “data” of parameter “FW” is 0 (Zero) (IPOS format)
l
The format is to indicate if there is an error between position command and present position.
l
Basically “IPOS” output will be closed only when residual pulses in the position error counter is
within the range set by “IN” parameter. In other state, it is open.
l
However, even residual pulses in the position error counter is within the “IN” value, output is
forced to open during pulses are generated internally when executing programmable indexer,
home return, jogging and operations via RS-232C.
(Executing programmable indexer, home return, jogging and operation through RS-
232C.)
l
Recommendation
Select “IPOS” format for pulse train operation or RS-232C operation.
l
When the positioning is stopped in the middle of the operation by emergency stop or overtravel
limit signal, IPOS output will stay closed if residual pulses of position error counter are within
the “IN” value.
l
When executing pulse train input operation, even pulses are being input, IPOS output is closed if
residual pulses in the position error counter are within “IN” value.
[This state tends to occur when executing low speed operation or feed forward
compensation is applied (“FF” parameter).]
