The following shows the servo motor rotation directions.
The positive/negative directions of the linear servo motor are as follows.
Negative direction
Positive direction
LM-H3/LM-F series
PA15 *ENR Encoder output pulses
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)
To set a numerator of the electronic gear, select "A-phase/B-phase pulse electronic gear
setting (_ _ 3 _)" of "Encoder output pulse setting selection" in [Pr. PC03].
The maximum output frequency is 4.6 Mpulses/s. Set the parameter within this range.
PA16 *ENR2 Encoder output pulses 2
Set a denominator of the electronic gear for the A/B-phase pulse output. To set a denominator
of the electronic gear, select "A-phase/B-phase pulse electronic gear setting (_ _ 3 _)" of
"Encoder output pulse setting selection" in [Pr. PC03].
