D-No.005 After Fastening Operation Standard setting: 000000
*****1: 1 Pulse Reverse
・After the end of fastening, the torque is reversed at the D-No. 121 [1 Pulse Reverse Torque High
Limit]. The 1 Pulse Reverse is performed at the D-No. 410 [1 Pulse Reverse Speed] for the
D-No. 316 [1 Pulse Reverse Time].
****1*: End Slope
・The reaction force of the tool at the end of fastening is suppressed.
Apply a current limit of 2/3 times the current at the end of fastening.
The current limit is decreased so that 200ms later, it is 0% and fastening is stopped.
****1*: Torque Recovery
･ After the target is reached, the standard torque is maintained for the D-No. 315 [Torque Recovery
Time]. The fastening speed during execution of the torque recovery is the D-No. 404 [3rd
Speed].
***1**: Servo Lock (Hold)
･ At the end of operation, the motor is locked to fix the top to prevent rotation of the tool. However,
if a backlash occurs in the gear part or socket, etc., rotation is performed within ranges that
include the backlash.
It can also be monitored by the fastening result mode D-No. 16 “Servo Lock Flag” of the indicator.
【Notes on servo lock】
Depending on the controller version, the servo lock by PLC I / O input signal
The release method is different.
****1*: Recovery Pulse
・A retightening operation after fastening is performed by pulsing.
Pulsing operation cycles at the D-No. 551 [Recovery Pulsing Speed] are executed for the number of
times defined by the D-No. 550 [Recovery Pulsing Count].
【 Notes on operation after fastening】
If the controller version is less than V1.305, operation will be limited after fastening.
・Recovery Pulse
It is not executed when “Torque Recovery” is enabled.
・End Slope
It is not executed when "Torque recovery" or "Recovery pulse" is enabled.
