9.1.8.1. Output Signal Format
l
The output signal format · · · either IPOS format or FIN format · · · can be selected by setting the
FW parameter.
◊
FW data : FIN format is selected when data
≠
0 (shipping set : FW1)
◊
FW0 : IPOS format
1 When data of parameter “FW” is not “0” (Zero) (FIN mode)
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 state
◊
IPOS output is always open and it closes only for the moment set by “FW” when the
positioning completes (The unit of closing time in “FW” is 100m sec. Shipping set FW1 :
100m sec.)
Recommendation
We recommend to use FIN mode when you use the programmable indexer in the Driver Unit.
l
“IPOS” will not be output for pulse train operation and jog operation.
l
When the positioning is disturbed in the middle of operation by the emergency stop or over-travel
limit switch, “IPOS” will not be output.
2 When “data” of parameter “FW” is 0 (Zero) (IPOS mode)
l
The format is to indicate if there is a difference between position command and current 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, jog and operations via the RS-232C communication.
Recommendation
Select “IPOS” mode for pulse train command operation or a positioning via the RS-232C
communication.
l
When the positioning is disturbed in the middle of the operation by emergency stop or over-travel
limit signal, IPOS output will stay closed if residual pulses of position error counter are within the
“IN” value.
l
When executing pulse train command 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).]
