Encoder output pulse setting
Set [Pr. PC03.1 Encoder output pulse setting selection]. Set the number of output pulses according to the set value.
■When [Pr. PC03.2] = "0" (servo motor-side encoder)
Setting value of [Pr. PC03.1]
"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)

4.13 A/B/Z-phase pulse output function
For servo motors and direct drive motors
Set the output pulses per revolution with [Pr. PA15
Encoder output pulses].
Output pulse = Setting value in [Pr. PA15] [pulse/rev]
If [Pr. PC03.2] is set to "1" (load-side encoder), [AL. 037
Parameter error] will occur.
Set the dividing ratio to the resolution per servo motor
revolution with [Pr. PA15 Encoder output pulses].

Set the A-phase/B-phase pulse electronic gear with [Pr.
PA15 Encoder output pulses] and [Pr. PA16 Encoder
output pulses 2].

Setting value of [Pr. PA16]
• When a servo amplifier with a firmware version earlier
than B2 is being used
[AL. 037] occurs.
• When a servo amplifier with firmware version B2 or later
is being used
A/B-phase pulses of the A/B/Z-phase differential output
type encoder are outputted.
• This function is only usable with a direct drive motor.
Setting [Pr. PA01.1 Operation mode selection] to "0"
(standard control mode) triggers [AL. 037].
• This is enabled when an A/B/Z-phase differential output
type encoder is used.
When a different encoder is connected, [AL. 037] occurs.
• Output pulse = A/B-phase pulse of A/B/Z-phase
differential output type encoder [pulse]
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.
For linear servo motors
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].
