1 SERVO PARAMETER DETAILS
1.4 Extension setting servo parameters group ([Pr. PC_ _ ])
• When [Pr. PC03.2] = "1" (load-side encoder)
[Pr. PC03.2_Encoder selection for encoder output pulse]
Select the encoder that the servo amplifier will use to output encoder output pulses.
This servo parameter can be used only in a fully closed loop system.
If "1" is selected for systems other than a fully closed loop system or a semi closed loop system (scale measurement function
enabled), [AL. 037 Parameter error] occurs.
This servo parameter cannot be set for the C-axis of multi-axis servo amplifiers.
For the settings, refer to the table for [Pr. PC03.1].

enabled
"0" (output pulse setting)
[AL. 037] occurs.
"1" (dividing ratio setting)
Set the dividing ratio relative to the resolution per servo
motor revolution with [Pr. PA15].
Set the dividing ratio relative to the travel distance of the
scale measurement encoder with [Pr. PA15].
"3" (A-phase/B-phase pulse
electronic gear setting)
Set the A-phase/B-phase pulse electronic gear with [Pr.
PA15] and [Pr. PA16].
Set the A-phase/B-phase pulse electronic gear with [Pr.
PA15] and [Pr. PA16].
"4" (A/B-phase pulse through output
setting)
• A/B-phase pulses are output when an A/B/Z-phase
differential output type encoder is used. If a different
encoder is connected, [AL. 037] occurs.
• The setting value in [Pr. PC03.0 Encoder output pulse -
Phase selection] is not applied.
• The setting values in [Pr. PA15] and [Pr. PA16] are not
applied.
Output pulse = A/B-phase pulse of A/B/Z-phase
differential output type encoder [pulse]
• A/B-phase pulses are output when an A/B/Z-phase
differential output type encoder is used. If a different
encoder is connected, [AL. 037] occurs.
• A/B/Z-phase differential output type encoders cannot be
used in the linear servo motor control mode or the direct
drive motor control mode.
• The setting value in [Pr. PC03.0 Encoder output pulse -
Phase selection] is not applied.
• The setting values in [Pr. PA15] and [Pr. PA16] are not
applied.
