Parameter
Frequency compensation function when the motor stops outside the orientation in-position
zone
When the motor stops before entering the in-position zone due to external force, etc., output
frequency is increased to move the shaft to the orientation stop position. The output
frequency is gradually increased to the creep speed of Pr. 352 "Creep speed". Note that this
function and the retry function can not be used together.
DC injection brake and servo torque selection when the position pulse comes off the in-
position zone after output of the orientation completion signal (ORA)
If the position pulse comes off the orientation in-position width, you can select a setting either
fixing a shaft with the DC injection brake or returning the motor to the orientation stop position
with servo torque.
Orientation operation end switch operation selection between DC injection brake or servo
torque
When ending the orientation operation, turn off the start signal (STF or STR), then turn off
the orientation command (X22). At this time, you can select when to turn off the orientation
completion signal (ORA) from between at turning off of the start signal or turning off of the
orientation command signal.
Selection of completion signal off or on when the motor stops outside of the in-position zone
after output of the orientation completion signal (ORA)
You can select the mode to turn off the completion signal or keep the completion signal on
(orientation fault signal (ORM) is not output) when the motor stops outside of the in-position
zone.
● Position loop gain (Pr. 362)
When servo torque function is selected using Pr. 358 "Servo torque selection", output frequency
for generating servo torque increases to the creep speed of Pr. 352 "Creep speed" gradually
according to the slope set in Pr. 362 "Orientation position loop gain".
Although the operation becomes faster when the value is increased, a machine may hunt, etc.
