# 0 CFR For retraction after threading in the threading cycles G92 and G76:
0: The type of acceleration/deceleration after interpolation for
threading is used together with the threading time constant
(parameter No. 1626) and FL feedrate (parameter No. 1627).
1: The type of acceleration/deceleration after interpolation for rapid
traverse is used together with the rapid traverse time constant and
FL feedrate.
NOTE
When this parameter is set to 1, an in-position
check is made before retraction. For retraction, the
rapid traverse rate (parameter No. 1420) is used,
regardless of the setting of parameter No. 1466.
When this parameter is set to 0, parameter No.
1466 is used as the feedrate for retraction. As
acceleration/deceleration used for retraction, only
acceleration/deceleration after interpolation is
used. Rapid traverse before look-ahead
interpolation and optimum torque
acceleration/deceleration are disabled.
1626 Acceleration/deceleration time constant in threading cycles for each axis
[Input type] Parameter input
[Data type] Word axis
[Unit of data] msec
[Valid data range] 0 to 4000
Set a time constant for acceleration/deceleration after interpolation in
the threading cycles G92 and G76 for each axis.
1627 FL rate for acceleration/deceleration in threading cycles for each axis
[Input type] Parameter input
[Data type] Real axis
[Unit of data] mm/min, inch/min, degree/min (machine unit)
[Minimum unit of data] Depend on the increment system of the applied axis
[Valid data range] Refer to the standard parameter setting table (C)
(When the increment system is IS-B, 0.0 to +240000.0)
Set an FL feedrate for acceleration/deceleration after interpolation in
the threading cycles G92 and G76 for each axis. Set 0 at all times
except in a special case.
