Applied Functions
Electronic Gear Ratio Setting (Pn009, Pn010)
*1 The encoder resolution is set as the numerator for full closing control.
Precautions for Correct Use
The electronic gear ratio must be set between 1/1000 x and 1000 x. If it is set outside the range,
the Parameter setting error (Alarm No.93.0) occurs.
To make the position command milder after the electronic gear setting, adjust it by the Position
Command Filter Time Constant (Pn222) or by the Position Command FIR Filter Time Constant
(Pn818)."
