Setting
• Perform soft start processing for the command pulses using the selected filter to gently accelerate
• Select the filter characteristics using the Position Command Filter Time Constant Setting (Pn4C).
• This function is effective in the following cases:
• The characteristics for each filter are shown below.
• Servomotor acceleration and deceleration are delayed further than the characteristics shown
Note The time constant will be as follows according to the setting of Pn4C.

• There is no acceleration/deceleration function in the command pulse (controller).
• The command pulse frequency changes abruptly, causing the machinery to vibrate during

Speed
This is a first-order lag filter for the command pulse input section. If the
command pulses change abruptly, this filter can be used to reduce the
stepping movement of the Servomotor.
The larger the setting, the larger the time constant (setting range: 0 to 7).
