(2) Output (Y)
(a) This outputs the results of the program control to the solenoid, magnetic
switch, signal lamp or digital indicator, etc.
(b) The output (Y) can be retrieved with the equivalent of one "A" contact.
(c) There is no limit to the number of "A" contacts and "B" contacts of the output
Yn that can be used in the program.
(d) The output number is expressed with a hexadecimal.

Program
The internal relay are auxiliary relays in the Motion CPU that cannot directly output to
an external source. F device doesn't provide the function as the annunciator (fault
detection).
(1) The relay is cleared when the power is turned OFF.
Latch setting can be applied to the system setting.
(2) There is no limit to the number of "A" contacts and "B" contacts of the internal
relays that can be used in the program.
(3) The internal relay number is expressed with a decimal.
(4) Part of internal relay (M) is used in the system of the Motion CPU for the
positioning dedicated signal etc. The use of that is restricted. Refer to the
"Q173D(S)CPU/Q172D(S)CPU Motion controller (SV13/SV22) Programming
Manual (REAL MODE)" or "Q173D(S)CPU/Q172D(S)CPU Motion controller
(SV22) Programming Manual (VIRTUAL MODE)" for details.
