(7) [Pr.411] Main shaft clutch smoothing method (150n)
Set the smoothing method for clutch ON/OFF.
Refer to Section 7.3.3 for details.
• 0: Direct.................................................. No smoothing
• 1: Time constant method (Exponent).... Smoothing with an exponential curve
based on the time constant setting.
• 2: Time constant method (Linear) ......... Smoothing with linear acceleration/
deceleration based on the time constant
setting.
• 3: Slippage method (Exponent)............. Smoothing with an exponential curve
based on the slippage amount setting.
• 4: Slippage method (Linear) .................. Smoothing with linear acceleration/
deceleration based on the slippage
amount setting.
(8) [Pr.412] Main shaft clutch smoothing time constant (150n)
Set a time constant when the time constant method is set in [Pr.411] Main shaft
clutch smoothing method (150n).
The time constant setting applies for both clutch ON/OFF.
