The following shows the servo motor rotation directions.
The positive/negative directions of the linear servo motor are as follows.
Positive direction
Setting range: 0, 1
PA15 Set the encoder output pulses from the servo amplifier by using the number of
output pulses per revolution, dividing ratio, or electronic gear ratio. (after

multiplication by 4)
Encoder
To set a numerator of the electronic gear, select "A-phase/B-phase pulse electronic
output pulses
gear setting (_ _ 3 _)" of "Encoder output pulse setting selection" in [Pr. PC19].
The maximum output frequency is 4.6 Mpulses/s. Set the parameter within this
range.
Setting range: 1 to 4194304
PA16 Set a denominator of the electronic gear for the A/B-phase pulse output.
