adjustment
TSC
• You can select a stop status after reaching the target point in "Standstill mode".
You can set the initial value when inputting programs in the parameter No.25 (De-
fault standstill mode).
• Selecting an appropriate mode reduces heat generation and power usage.
• You can check the current passing through the motor on the "Monitor" screen of
the setup tool D-STEP.

Invalid
⿟ The servo will be turned OFF immediately after reaching and the current set in the parameter
No.11 (Cur. limit at stop)
( → P.5-20) continues to flow.
⿟
Although the actuator maintains the current position with the torque generated by this current,
the position will not be re-adjusted in the event of misalignment since the servo is OFF.
2-2
Auto servo OFF 1 (ASO 1)
⿟
Once reached, the servo will be turned OFF after the elapse of the time set in the parameter
No.17 (Auto servo OFF time 1)
( → P.5-20) .
⿟ The present position cannot be retained because the current becomes 0 after the servo is turned OFF.
⿟
If the position deviation caused by external force (difference between the command value and
the current value) exceeds the parameter No.30 (Position deviation)
( → P.5-21) the alarm of the
alarm code No.32 (Excessive position error (deviation)) will be generated.
( → P.6-5)
Note that the alarm will be generated only when the next move command is executed.
⿟ If the position deviation is within the permissible position deviation, the operation can be contin-
ued by specifying and starting the next STEP No. You also can continue to use the current STEP
No. to start an operation (returning to the "Position" of this STEP No.).
2-3
Auto servo OFF 2 (ASO 2)
⿟ Once reached, the servo will be turned OFF after the elapse of the time set in the parameter No.18 (Auto
servo OFF time 2)
(
→
P.5-20) .
⿟ Other operations are same as 2-2 Auto servo OFF 1 (ASO 1) ( → P.5-6) .
You can change the signal for positioning completion (pin.30), signal for positioning completion, in
the parameter No.37 (IN-POSI signal type) (
→
P.5-22) .
2-4
Auto servo OFF 3 (ASO 3)
⿟
Once reached, the servo will be turned OFF after the elapse of the time set in the parameter No.19 (Auto
servo OFF time 3)
( → P.5-20) .
⿟ Other operations are same as 2-2 Auto servo OFF 1 (ASO 1) ( → P.5-6) .
