7.2 Clutch
There are two types of clutch: the smoothing clutch and the direct clutch.
These two clutches operate in the same way; the difference is that with the
smoothing clutch, acceleration and deceleration processing by smoothing
processing is executed when the clutch is switched ON and OFF but this does not
happen with the direct clutch.
(1) Comparison of smoothing clutch and direct clutch
(a) Smoothing clutch
When the clutch is switched ON/OFF, the output to the output shaft is
executed by acceleration and deceleration processing (smoothing proces-
sing) in accordance with the smoothing time constant or amount of slip set
in the clutch parameters.
(b) Direct clutch
When the clutch is switched ON/OFF, output to the output shaft is executed
without acceleration and deceleration processing.
