8.6.1.7 Function of outputs
O1
♦
O1="1" if there is no error for group E1 ... E57.
♦
O1="0" if there is an error for group E1 ... E57; the drive does not accept
positioning commands.
O2
♦
O2="1" if there are no errors ≥E58.
♦
O2="0" if there is an error ≥E58.
O2 is assigned the "Idle display" function via P227 bit 1="1" (see Page ).119
O3
♦
When "1" is displayed, this indicates that a reference system has been defined,
i.e. there is information about the position of machine zero.
♦
When in "Normal mode", positioning is only possible when O3="1".
♦
By using an absolute value sensor and the relevant option (O1), O3="1" remains
as such even if the unit has been switched off in the meantime.
♦
Once the "Find machine zero" function has been activated (I1&I2="1"), O3="0"
until machine zero is found.
O4
♦
"Ready for START" is used for program control.
♦
O4 is set,
♦
if the program is at a WAIT START instruction and waiting for the START signal,
♦
after an interruption with STOP or BREAK and these signals are no longer
present,
♦
after a corrected error condition and
♦
after Power On.
♦
at program end with the END command.
♦
O4 has no significance for direct command specifications.
O5
♦
O5 is set to "0" when starting a positioning process; this applies for POSA,
POSR, WAIT POSA, WAIT POSR, approach real zero, approach machine zero,
Hand+, Hand-.
♦
O5 is set once the positioning has been completed in the correct manner. This
applies for POSA, POSR, WAIT POSA, WAIT POSR, approach real zero.
POSR 0 causes the brief resetting of O5.
♦
Conditions for O5="1":
♦
The actual position value is in the positioning window (+/-P14) and
♦
the nominal value sensor has reached the target point of the nominal value
specification.
♦
O5 is set in speed control mode, if the nominal value generator has processed
the speed ramp.
