Speed Filter - Vexta aStep AS Series Operating Manual

Speed filter

Use the speed-filter selection switch "V.FIL" to select the filter time constant that determines the
motor's response to pulse input.
The switch provides a selection of 16 levels ranging between "0" and "F."
When a larger value is selected, it will reduce shock when the motor is started and stopped, and
will minimize low-speed vibration.
An unnecessarily large filter time constant, however, will smooth out the motor movement
further but with a reduced ability to synchronize to the pulse input and extended settling time
when stopping. Select an optimal value to fit the load and application.
