description
This filter is a primary delay filter that is inserted after the scaling function in
the command pulse input portion.
• You can set-up the time constant of the smoothing filter in
8 steps with Pr4C.
You can set-up the conditions for clearing the position error counter, i.e. for
issuing the counter clear signal (CL: CN I/F Pin 30).

Purpose of this filter
• Reduce the stepwise motion of the motor that may appear when the command input is rough.
• The command input may become rough when:
1) The scale ratio is large (10 times or greater)
2) The command frequency is low.
