5 DATA USED FOR POSITIONING CONTROL
Pr.84 Restart allowable range when servo OFF to ON
(1) What is the restart function when servo OFF to ON ?
The QD75MH restart function when servo OFF changes to ON, performs
continuous positioning operation (positioning start, restart) when the servo is
switched from OFF to ON in the stopped state (including servo emergency
stop).
Restart when servo OFF changes to ON can be performed when the
difference between the last command position for the QD75MH when it
stopped and the present value when servo OFF changed to ON, is less than
the value set in the buffer memory for the restart allowable range setting.
(a) Servo emergency stop processing
1) For stop caused by a servo emergency stop signal, positioning
operation is judged as stopped and can be restarted if the difference
between the last command position for the QD75MH when the servo
stop signal turned ON and present value at the time the servo stop
signal turned OFF is lower than the value set in the buffer memory
for the restart allowable range setting.
