Motor Torque offset
(Wait time for angle judgment in loosening
operation)
This setting specifies the required time, based on the angle and speed
of the driver's loosening operation. The unit is ms.
Reverse stand-by
(Wait time for angle judgment in loosening
operation)
This is the setting range of the required time, calculated from the angle
and speed of the driver's loosening operation. The unit is ms.
Add angle range
(Additional tightening angle judgment
range)
This is the range for the angle judgment in additional tightening. The
setting range is expressed in negative (-) degrees.
Reverse angle range
(Loosening angle judgment range)
This is the range for the angle judgment in loosening. The setting range
is expressed in negative (-) degrees.
Pattern 3, Reverse torque – Full
(Torque for pattern 3 loosening operation -
Negative percentage of full tightening
torque)
This setting specifies the torque for the reverse rotation, in terms of
negative torque relative to the full tightening torque, to prevent
excessive looseness in the screw when the loosening operation in
pattern 3 is performed.
The unit is -%.
Torque down filter setting
1st step
(Torque-down filter setting -
Step 1 torque)
Set this parameter to reduce the spring-back of the bit that occurs
when the servo is turned OFF after the pattern is complete.
The torque limit setting is changed based on the parameters specified
for steps 1, 2, and 3, in that order.
The unit is %. * See Chapter 16.
Torque down filter setting
2nd step
(Torque-down filter setting -
Step 2 torque)
Set this parameter to reduce the spring-back of the bit that occurs
when the servo is turned OFF after the pattern is complete.
The torque limit setting is changed based on the parameters specified
for steps 1, 2, and 3, in that order.
The unit is %. * See Chapter 16.
Torque down filter setting
3rd step
(Torque-down filter setting -
Step 3 torque)
Set this parameter to reduce the spring-back of the bit that occurs when
the servo is turned OFF after the pattern is complete.
The torque limit setting is changed based on the parameters specified
for steps 1, 2, and 3, in that order.
The unit is %. * See Chapter 16.
Torque down filter setting Wait Time
(Torque-down filter setting -
Wait time)
Set this parameter to reduce the spring-back of the bit that occurs
when the servo is turned OFF after the pattern is complete.
The wait time specifies the amount of time to wait before applying
each change to the torque limit setting.
The unit is msec. * See Chapter 16.
