Description of I/O Signals

Neither positioning cancel nor pause gives effects on cycle end detection.
When positioning data number 15 is reached during sequential operation, the cycle end process
is executed.
If data continuation designation is included in positioning data, operation starts at the next data
having no data continuation designation.
Homing completion: Sequence output signal (Reference value 22)
This signal is turned on after the homing motion is finished.
 Function
This signal is turned on after the homing motion is normally finished. It remains turned on if the
feedback position is within PA2_17 (home position detection range) around PA2_16 (home
position after homing completion).
The signal is always turned on after homing if PA2_17 (home position detection range) is "0" or the
maximum value.
The home position is the stopping point after a homing motion is finished, or a position at which
position preset is executed. It does not mean the "0" position.
 Parameter setting
To assign homing completion to a sequence output terminal, specify the corresponding value
("22") to the output terminal function setting parameter.
Zero deviation: Sequence output signal (Reference value 23)
The signal is turned on if the deviation (deviation amount) retained in the servo amplifier becomes
within the reference value under position control.
Whether the servomotor has reached close to the command position can be checked.
 Function
The signal is turned on if the difference (deviation amount) between the command position and
feedback position is within the reference value of PA1_32 (zero deviation width/in-position range).
The signal status is retained in control modes other than position control mode (such as torque
control mode).
Position deviation will not be generated despite the reference value of PA1_32.
