Setting Method [A] - Mitsubishi Electric MR-J5 Series User Manual

Setting method [A]

The encoder output pulse function can be used by setting the following servo parameters. For output specifications of Z-
phase pulse, refer to the following.

Outline
Set the encoder output from the servo amplifier by using the number of output
pulses per revolution, dividing ratio, or electronic gear ratio. (after multiplication by
4)
The setting value varies depending on [Pr. PC19.1 Encoder output pulse setting
selection].
Initial value: 4000 [pulse/rev]
Set a denominator of the electronic gear when selecting "3" (A-phase/B-phase
pulse electronic gear setting) in [Pr. PC19.1 Encoder output pulse setting
selection]. This is not used for other settings.
Initial value: 1
Set the phase of A-phase and B-phase.
0: Increasing A-phase 90° in CCW or positive direction (initial value)
1: Increasing A-phase 90° in CW or negative direction
Select the setting method for the number of output pulses.
0: Output pulse setting (initial value)
1: Dividing ratio setting
2: The same output pulse setting as the command pulse
3: A-phase/B-phase pulse electronic gear setting
4: A/B-phase pulse through output setting
Linear servo motor:
The output pulse setting cannot be used. When "0" is set, the
condition is the same as when "1" is set.
Set the dividing ratio to the travel distance of the linear servo
motor with [Pr. PA15 Encoder output pulses].
