When synchronous speed is affected due to low resolution and generates noises
(not a high-pitched but a rough sound), the users can use this parameter to set
low-pass filter time constant to solve the problem. Please note that the the
frequency response of low-pass filter must be faster than synchronous speed
frequency response.

The electronic gear numerator value can be set via GNUM0, GNUM1 (refer to
Table 7.A).
When the GNUM0, GNUM1 are not defined, the default of gear numerator value is
set by P1-44.
When the users wish to set the gear numerator value by using GNUM0, GNUM1,
please set P2-60 ~ P2-62 after the servo motor has been stopped to prevent the
mechanical system vibration.
