range
• Position Command Filter Time Constant is the first-order lag filter that is inserted after the electronic
gear ratio for the command pulse input.
• Purposes of Position Command Filter Time Constant:
• This parameter is used basically for reducing the stepwise movement of the Servomotor with
sparse command pulse input
• Specifically, sparse command pulse input may occur in the following cases:
The electronic gear ratio is set to a large value (10 or higher).
The command pulse frequency is low.

*2 The Servomotor may operate at a higher speed than the original
command speed immediately after filter switching operation, if accumu-
lated pulses remain in the filter after a change in the filter value.
