This parameter specifies the period from when a skip signal is input to
when the next skip signal can be input for the continuous high-speed
skip function and EGB axis skip function. This parameter is used to
ignore chattering in skip signals.
If a value that falls outside the valid range is specified, the setting is
assumed to be 24 msec.

Skip signal

This signal is ignored.

When high-speed skip signals are used and bit 5 (CSE) of parameter
No. 6201 is set to 1, signals are handled as follows:

If G31P98 is specified, skip operation is not performed for a set period
of time after the torque limit skip arrival signal is set to 1.
If G31P99 is specified, skip operation is not performed for a set period
of time after the torque limit skip arrival signal is set to 1.
However, if a skip signal is input, skip operation is performed,
regardless of the period of time set in this parameter.
