1197 Maximum feedrate during chopping
[Input type] Parameter input
[Data type] Realaxis
[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 - +240000.0)
Set the value that will be used to limit the chopping rate. When this
parameter is set to "0" for the chopping axis, the rapid traverse rate
(parameter No. 1420) will be used to limit the chopping rate.
1198 Chopping rate for enabling bottom dead point overshoot damp control when
the chopping rate is changed
[Input type] Parameter input
[Data type] Real
[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 - +240000.0)
Bottom dead point overshoot damp control is enabled when the
chopping rate (command-specified rate overridden with a certain
value, not including a portion increased due to chopping
compensation) exceeds a value specified in this parameter.
Bottom dead point overshoot damp control is disabled if the
chopping rate is lower than the value specified in this parameter.
If bottom dead point overshoot damp control is enabled, changing
the override value, changing the command-specified rate, and
interlocking are enabled only within the range between the top dead
point and the bottom dead point. Any attempt to change them
within the range between the bottom dead point and the top dead
point is ignored.
This parameter can be specified only when chopping is canceled
(has not been started). Any attempt to change the parameter is
ignored during chopping.
If this parameter is 0, overshoot damp control is disabled for all
rates.
1881 Permissible error at start of chopping compensation
[Input type] Parameter input
[Data type] Integer
[Unit of data] detection unit
[Valid data range] 0 - 99999999
Chopping compensation is made when the difference between the
underrun amounts at the top and bottom dead centers due to the
servo position control delay is less than the setting. When 0 is
specified for this parameter, no compensation is made.
