7 Operation
7.4.3 Acceleration/Deceleration Function
7-20
(5) Second-step Linear Deceleration Parameter
Set the second-step linear deceleration, when 2-step deceleration is used.
When the first step deceleration parameter is used, set Pn80E as the parameter for first-step deceleration.
(6) Deceleration Parameter Switching Speed
Set the speed for switching between first-step and second-step deceleration when 2-step deceleration is used.
When first-step deceleration is used, set the deceleration switching speed (Pn80F) to 0.
To use trapezoidal acceleration/deceleration without using second-step acceleration/
deceleration, set the parameters Pn80C and Pn80F to “0”, and set the acceleration speed
parameter, Pn80B, and the deceleration speed parameter, Pn80E.
(7) Exponential Position Reference Filter Bias
Set the bias when an exponential function filter is used for the position reference filter.
(8) Exponential Position Reference Filter Time Constant
Set the time constant when an exponential function filter is used for the position reference filter.
(9) Movement Average Position Reference Filter Movement Average Time
Set the average time of movement when a movement averaging filter is used for the position reference filter. Set
this parameter when using S-curve acceleration/deceleration.
