Chapter 6 Fastening Operation
PAGE 6-73
Other / Time
D-No.540 Number of Accept [#] Setting range: 0~99
When using the “Batch’ function, the number of Accept fastenings to designate a ‘Batch OK’.
(Example: if set to ‘4’, you would need four consecutive Acceptable fastenings to output a ‘Batch OK’
signal and light the TOTAL OK on the front of the controller)
D-No.541 Angle Head Torque Variation Rate [%] Default value: 0, Setting range: 0~100
When torque reaches Standard Torque and the monitored torque curve variation shows the
percentage (%) of torque variation exceeds this setting, an angle head error occurs (abnormal
A.09-10 “Angle head torque variation abnormal”).
*The torque variation check can only be performed with an angle head type (-A) tool.
D-No.542 Pause-Between-Steps Servo Lock Time [msec] Default value: 5
Setting range: 0~200
Sets the servo lock time between steps. (Servo lock after 1
st
or 2
nd
Torque)
This is used when a 2-step fastening or 3-step fastening is performed.
D-No.543 Pause-Between-Steps Restart Time [msec] Default value: 15
Setting range: 0~200
Sets the pause time (no rotation) after the fastening has stopped between steps (when function is
enabled)
When the restart time is increased, the fastening time is correspondingly increased.
(Can be used during 2-step fastening or 3-step fastening only)
D-No.544 Ramp Down Time Setting range:0~200ms (Default value: 0)
D-No.545 Final Ramp Down Time Setting range:0~200ms (Default value: 0)
Sets the speed ramp down profile.
Note: May be increased to prevent damage to the tool that occurs during deceleration when high
speeds are used and may affect torque accuracy.
Ramp Down Time ••• Freerun speed ￫ Attainment of ramp down start torque ￫ Speed ramp down
￫ 1st speed
Note: For older versions, when the front panel SW1-3 is turned ON
(deceleration operation), the ramp down time is set to 16msec
Final Ramp Down Time ••• Ordinary stop (OK/NG/START_OFF)
