This setting has no effect on the number of instruction pulses. The filter time is not as long as possible. If the filter time is longer, the delay time will be longer too, and the response time will be correspondingly longer. It is an illustration of several kinds of position filtering.

2114 2114  The encoder adapted to the multi-turn absolute value system is equipped with 16-bit RAM memory. Compared with the single-turn absolute value, it can additionally memorize the number of turns of the 16-bit encoder. The multi-turn absolute encoder is equipped with a battery (the battery is installed on the encoder cable with a battery unit), which can achieve direct internal high-speed readings and external output without the need for external sensors to assist memory positions. The types and information of encoders adapted to VD2 series servo drives are shown as below.
