P089 Resolution ratio of resolver 0 ～ 3 0 ALL
Note 1: Absolute and resolver type servo driver are valid. In default (the electronic gear ratio is
1:1), the command pulse number needed for motor rotating one circle = P027×P028.
In this example, the primitive resolution ratio of 17 bits absolute type is 2
17
=131072. Users
need to make sure the result of P027×P028 is not more than 131072.
The resolution ratio of resolver depends on parameter P089. Users need to make sure the
result of P027×P028 is not more than the resolution ratio set by P089.
