In-Position [Inp]: Sequence Output Signal (Reference Value 2) - Fuji Electric Alpha7 VV User Manual

CHAPTER 2 WIRING

In-position [INP]: Sequence output signal (Reference value 2)

This signal is turned on after a positioning motion is finished.
 Function
(1) Status of in-position signal
2
The state under position control is shown in the table below.
If servo-on [S-ON] is turned off
If servo-on [S-ON] is turned on
Upon OT detection
At deviation clear
If forced stop [EMG] is turned off
Upon alarm
This signal is always turned on under speed control and torque control.
(2) In-position signal output format
PA1_33 (in-position output format) at either "0" (level) or "1" (single shot) can be set.
 Parameter setting
To assign the in-position [INP] to a sequence output terminal, specify the corresponding value ("2")
to the output terminal function setting parameter.
 Signal activation condition
(1) At power-on
Level: ON
Single shot: OFF
(2) During command pulse input operation
Level: The signal is turned on if conditions (A) and (B) below are satisfied.
Single shot: If conditions (A) and (B) above are satisfied, the signal is turned on for time
2-74
Description of I/O Signals
Factor
(A) The rpm of the servomotor is within the setting of PA1_30 (zero speed range).
(B) The difference (deviation amount) between the command position (command pulse
input) and feedback position is within the setting of PA1_32 (zero deviation
range/in-position range).
specified at PA1_34 (In-position min. OFF time/single shot ON time:) and then it is
turned off.
However, if the zero deviation signal or the zero speed signal is turned off while the
signal remains turned on, the signal is forcibly turned off.
