In-Position [Inp]: Sequence Output Signal (Reference Value 2) - Fuji Electric ALPHA7 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
Position command on VS type
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 IQ area (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 the time
2-80
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 output time: VS type) (In-position min. OFF
time/single shot ON time: LS type) and then it is turned off.
However, if the zero deviation signal is turned off while the signal remains turned on,
the signal is forcibly turned off.
