4.6.4 Smoothing
A filter can be applied in the servo drive to a constant-frequency reference pulse.
(1)Selecting a Position Reference Filter
* After changing the parameter, turn OFF the power once and turn it ON again to enable the new setting.
(2)Filter-related Parameters
■Important
When the position reference acceleration/deceleration time constant (Pn204) is changed, a value with no reference
pulse input and a position error of 0 will be enabled. To ensure that the setting value is correctly reflected, stop the
reference pulse from the host controller and input the clear signal (CLR), or turn OFF to clear the error.
This function provides smooth servomotor operation in the following cases.
·When the host controller that outputs a reference that cannot perform acceleration/deceleration processing.
·When the reference pulse frequency is too low.
·When the reference electronic gear ratio is too high (i.e., 10× or more)
