4.13 A/B/Z-phase pulse output function
Encoder output pulse setting
Set [Pr. PC19.1 Encoder output pulse setting selection]. Set the number of output pulses according to the set value.
■
When [Pr. PC19.2] = "0" (servo motor-side encoder)
Setting value of [Pr.
PC19.1]
For 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].
Output pulse = Setting value in [Pr. PA15] [pulse/rev]
When [Pr. PC19.2] is set to "1" (load-side encoder), [AL. 037
Parameter error] occurs.
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 to the resolution per servo motor
revolution with [Pr. PA15 Encoder output pulses].
Set the dividing ratio to the travel distance of the linear servo
motor with [Pr. PA15 Encoder output pulses].
"2" (the same output pulse
setting as the command
pulse)
Feedback pulses from the encoder are processed and outputted as follows.
Feedback pulses are outputted in the same pulse unit as the command pulse.
The settings of [Pr. PA15 Encoder output pulses] and [Pr. PA16 Encoder output pulses 2] are not used.
"3" (A-phase/B-phase pulse
electronic gear setting)
Set the A-phase/B-phase pulse electronic gear with [Pr. PA15
Encoder output pulses] and [Pr. PA16 Encoder output pulses
2].
Set the A-phase/B-phase pulse electronic gear with [Pr. PA15
Encoder output pulses] 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 of the A/B/Z-phase differential output
type encoder are outputted.
• 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. PC19.0 Encoder output pulse - Phase
selection] is not applied.
The setting values in [Pr. PA15] and [Pr. PA16] are not
applied.
• 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. PC19.0 Encoder output pulse - Phase
selection] is not applied.
The setting values in [Pr. PA15] and [Pr. PA16] are not
applied.
