Present position setting completed

END;
Note (1) Make sure to create a program to confirm a response for a command.
(2) After setting is completed, turn ON “Counter 1 count enable (OW0050-
3bit)”. With the output variable OFF, the present value of the counter on
the MC Unit cannot be monitored.
(3) When executing a synchronous command having the input of the counter
module as the master axis, the link option “When master axis is detected”
cannot be used to start synchronization (ignored). The link option “When
master axis reaches link start position” can be used.
(4) Executing present position preset on the module during execution of syn-
chronous command makes the MC Unit to recognize (though not true)
that the axis was moved from the position before the preset to the one af-
ter the preset, which causes the slave axis to operate.
I/O variables specification The following is the relations between the counter module with the above
parameter settings and I/O variables in the MC Unit. (The addresses are the
ones for the counter module allocated as Axis 5.)
Input variables
Address Bit Symbol Name Description
IW0050 0 RDY Ready Indicates the result of self-diagnosis for the module.
ON: Normal
OFF: Abnormal
1 ACK Setting normal Indicates the setting operation was completed normally.
Stays ON while the setting signal is ON.
2 ERR Setting error Indicates the setting operation caused an error.
Stays ON while the setting signal is ON.
3 to 7 Not used
8 CARY1 Counter 1, Carry Turns ON for 1 scan when counter’s current value with
incremental pulses exceeded counter’s upper limit value.
9 BORW1 Counter 1, Borrow Turns ON for 1 scan when counter’s current value with
decremental pulses exceeded counter’s lower limit value.
10 N1 Counter 1, Notch out-
put status Indicates the status of external Notch output.
ON: External Notch being output
11 L1 Counter 1, Latch input
status Indicates the status of external Latch input.
ON: External Latch being input
12 CARY2 Counter 2, Carry Turns ON for 1 scan when counter’s current value with
incremental pulses exceeded counter’s upper limit value.
13 BORW2 Counter 2, Borrow Turns ON for 1 scan when counter’s current value with
decremental pulses exceeded counter’s lower limit value.
14 N2 Counter 2, Notch out-
put status Indicates the status of external Notch output.
ON: External Notch being output
15 L2 Counter 2, Latch input
status Indicates the status of external Latch input.
ON: External Latch being input
