A/B/Z-phase pulse output function

This function outputs position information from the servo motor or the load-side encoder in the form of A/B/Z-phase pulses.
Restrictions [G] [B]
• The encoder Z-phase pulse is not output when the MR-J5W_-_, the MR-J5D2-_G_, or the MR-J5D3-_G_ is used.
• A/B/Z-phase pulses are not output from the C-axis encoder when the MR-J5W3- or the MR-J5D3-_G_ is used.
• With the linear servo motor, [Pr. PC03.1 Encoder output pulse setting selection] = "0" (output pulse setting) cannot be used.
If set to "0", A/B/Z-phase pulse output uses the dividing ratio setting.
• [Pr. PC03.1 Encoder output pulse setting selection] = "4" (A/B-phase pulse through output setting) is for the A/B/Z-phase
differential output type encoder. If an encoder other than the A/B/Z-phase differential output type encoder is connected, [AL.
037] will occur.
• When the A/B-phase pulse output function is used for multi-axis servo amplifiers, restrictions vary depending on the
network. For detailed contents, refer to the User's Manual (Introduction).
• A/B/Z-phase pulses are not output when using the safety sub-function by network ([Pr. PSA01.0] is "1", [Pr. PSA01.1] is "1")
with the MR-J5D2-_G_ or the MR-J5D3-_G_.
Restrictions [A]
• With the linear servo motor, [Pr. PC19.1 Encoder output pulse setting selection] = "0" (output pulse setting) cannot be used.
If set to "0", A/B/Z-phase pulse output uses the dividing ratio setting.
• [Pr. PC19.1 Encoder output pulse setting selection] = "4" (A/B-phase pulse through output setting) is for the A/B/Z-phase
differential output type encoder. If an encoder other than the A/B/Z-phase differential output type encoder is connected, [AL.
037] will occur.
Precautions
• Set the encoder output pulse to a value that is four times that of the A-phase pulse.
• The encoder output pulse signal uses positive logic.

Setting method [G] [B]

Name Outline
Encoder output pulses 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. PC03.1 Encoder output pulse setting
selection].
Initial value: 4000 [pulse/rev]
Encoder output pulses 2 Set a denominator for the electronic gear for when selecting "3" (A-phase/B-phase
pulse electronic gear setting) in [Pr. PC03.1 Encoder output pulse setting selection].
This is not used for other settings.
Initial value: 1
Encoder output pulse - Phase Set the phase for the A-pulse and the B-pulse.
selection 0: Increasing A-phase 90° in CCW or positive direction (initial value)
1: Increasing A-phase 90° in CW or negative direction
Encoder output pulse setting Select the method for setting the number of output pulses.
selection 0: Output pulse setting (initial value)
1: Dividing ratio setting
3: A-phase/B-phase pulse electronic gear setting
4: A/B-phase pulse through output setting
Encoder selection for encoder Select a servo motor encoder or load-side encoder for the encoder to output pulses.
output pulse 0: Servo motor-side encoder (initial value)
1: Load-side encoder
