Offset Check
D-No.001 Fastening Steps Standard Setting
：
1
Set the number of fastening steps.
1
：
1 Step Fastening … Fasten up to [103: Standard Torque] or [202: Standard Angle] with no
intermediate stopping.
2
：
2 Step Fastening … Fasten up to [105:1
st
Torque] or [203:1
st
Angle], stop once and then fasten up to
the set standard torque/angle value. The downtime between steps varies by single of multi system
setup.
3
：
3 Step Fastening … Fasten up to [105:1
st
Torque] or [203:1
st
Angle], stop, then fasten up to [109:2
nd
Torque] or [204:2
nd
Angle] and stop again. Finally fasten up to the set standard torque/angle value.
The downtime between steps varies by single of multi system setup.
D-No.002 Fastening Option Standard Setting
：
00000
Set the fastening options.
0000 1
：
Reverse Before Fastening (Single System Only)
・
Reverse at D-No.406[Reverse 2 Speed] for D-No.501[Reverse 2 Revolutions] before fastening
starts
000 1 0
：
Fastening Direction CCW
・
Specialized for fastening with a left-hand screw etc. which need to fasten in the opposite direction
of normal fastening. (CW direction (right hand thread)) Reverse rotation is in the CCW direction.
00 1 00
：
Hold Torque Between Steps
・
For 2-Step Fastening, the torque is held at one quarter of the last step torque value from when
1STEP (1
ST
torque, 1ST angle) stops until the next step is initiated.
・
For 3-Step Fastening, the torque is held at one quarter of the last step torque value from when
1STEP (1
ST
torque, 1ST angle) stops or when 2STEP (2
ND
torque, 2
ND
angle) stops until the next
step is initiated.
0 1 000
：
Disable Curve Data Storage
・
Fastening curve will not be saved in the controller after fastening
1 0000
：
Disable Angle Count below Snug Torque
・
Usually the angle value is measured regardless of the torque value after SNUG torque is detected. If
the this function is enabled, the angle value measurement is suspended if the torque value drops below
SNUG torque, then resumes if/when
the torque goes above SNUG torque.
