7.1.9 External Deceleration
Overview
The control axis is externally decelerated. The feedrate is decelerated
by the external deceleration signals from the machine. The
deceleration rate is set by the parameters.
The external deceleration signal are provided for each axis and
direction.
As five types of deceleration condition settings can be dynamically
selected by the signals.
External deceleration can be applied to rapid traverse rate, cutting
feedrate, and manual handle feedrate.
- Rapid traverse and cutting feed
Five types of deceleration conditions can be set by the parameters.
When deceleration conditions specified by multiple external signals
input during machining are conflicted, the condition with the lowest
external deceleration rate is applied.
External deceleration settings 2, 3. 4, and 5 can be switched between
enabled and disabled by the parameters.
- Manual handle feed
Five types of deceleration conditions can be set by the parameters. For
handle feed, the maximum feedrate is switched when the external
deceleration signal in the positive or negative direction for the handle
axis is set to 0. When multiple conditions are conflicted, the condition
with the lowest maximum feedrate is applied.

[Classification] Input signal
[Function] These signals specifies whether to apply external deceleration to each
direction for each control axis. The sign + or - preceding ED indicates
the direction of feed which is decelerated. The number following ED
indicates the number of external deceleration setting. The last number
indicates the number of a control axis.
