[Pr. PC03.1_Encoder output pulse setting selection]
Select the encoder output pulse setting.
This servo parameter cannot be set for C-axis.
If this servo parameter is set to "0" while [Pr. PC03.2 Encoder selection for encoder output pulse] is set to "1", [AL. 037
Parameter error] occurs.
When an encoder other than an A/B/Z-phase differential output type encoder is connected, setting this servo parameter to "4"
causes [AL. 037] to occur.
0: Output pulse setting
1: Dividing ratio setting
3: A-phase/B-phase pulse electronic gear setting
4: A/B-phase pulse through output setting

Settings of [Pr. PC03.1] and [Pr. PC03.2]
• When [Pr. PC03.2] = "0" (servo motor-side encoder)
*1 If this value is set when using the rotary servo motor, [AL. 037] occurs.

Setting value of [Pr. PC03.1]
For rotary servo motors and direct drive
motors
For linear servo motors
"0" (output pulse setting)
Set the output pulses per revolution with [Pr. PA15
Encoder output pulses].
If [Pr. PC03.2] is set to "1" (load-side encoder), [AL. 037]
will occur.
Output pulse = Setting value of [Pr. PA15] [pulse/rev]
The output pulse setting cannot be used. When "0" is set,
the condition is the same as when "1" is set.
"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
linear servo motor 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 Encoder output pulses 2].
Set the A-phase/B-phase pulse electronic gear with [Pr.
PA15] and [Pr. PA16 Encoder output pulses 2].
"4" (A/B-phase pulse through output
setting)
• When a servo amplifier with a firmware version earlier
than B2 is being used, [AL. 037] occurs.
• 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.
• 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.
