FX Series Positioning Controllers Parameters 4

The table below shows the setting of major electronic gears and pulse rates obtained by the
above calculation.
*1 If the electronic gear is less than "1/1", you can set it to "1/1" and limit the command pulse
frequency given by the positioning unit. In such a case, make sure that the rotation speed
of the servo motor does not exceed the maximum rotation speed. (You can set the maxi-
mum speed by PARA. 4 in the positioning unit.)
The actual values may be different depending on the specifications of the used servo motor/
servo amplifier and the required operation speed. Thoroughly read the instruction manuals
of the servo motor and the servo amplifier, then set proper values in accordance with the
required application.
