D-No.006
After Fastening Operation Standard Setting
：
0000
Set the operation to be performed after the fastening operation is complete.
0001
：
1 Pulse Reverse
・
Prevent a socket from sticking after the fastening ends.
Reverse at D-No. 408 [Reverse 3 Speed] during D-No.321 [1 Pulse Reverse Time].
After the end of fastening, torque is applied to the D-No.120 [1 Pulse Reverse Torque High Limit].
0010
：
End Slope (Reduce Fastening Reaction)
・
Reduces the release of torque energy at the end of a fastening cycle by gradually releasing the torque
over a given time period. Normally, the motor power is turned off when the target torque / angle is
reached which can cause an abrupt ‘jerking motion’ when the torque energy is released – the use
of this function reduces this by allowing the energy to dissipate more smoothly. This function is
helpful in operator held applications and also may help reduce wear of tooling at high torque
levels where torque reaction can be very high.
0100
：
Torque Recovery
・
Once Standard Torque is reached, the torque is maintained for D-No.315 [Torque Recovery Time].
The fastening speed during torque recovery is set at D-No. 404 [3
rd
Speed] (Should be no more
than 3rpm or 5rpm.)
1000
：
Servo Lock
・
At the end of a cycle with Servo Lock enabled, the motor rotor is electrically locked to prevent
rotation of the tool. (External gears, socket and/or socket extensions may experience slight
movement even though the servo lock is enabled due to backlash in the drive connections).
The function will also work in the Reverse direction using the Reverse input signal or Reverse
1-3 being called from a internal sequence.
The fastening result data is output after the Servo Lock is released.
The real time monitoring is available while the Servo Lock is on.
A RESET pulse <500msec can be used to stop and hold/lock the spindle while rotating in cycle.
(a RESET pulse >500msec will reset and turn off the hold/lock function)
Servo Lock can be released when a START signal is ON, RESET signal is ON, BYPASS signal is
ON, or STOP is OFF.
(use of this function can be monitored from the controller display in the Fastening Result Mode: D-No.
16 “Servo Lock Flag” would be set to “1”.
