1 SERVO PARAMETER DETAILS
1.4 Extension setting servo parameters group ([Pr. PC_ _ ])
[Pr. PC27_Function selection C-9 (**COP9)]
[Pr. PC27.0_Encoder pulse count polarity selection]
Select a polarity of the linear encoder or load-side encoder.
If the scale measurement function is enabled in the linear servo motor control mode, the polarity of the servo motor-side
encoder changes.
0: Encoder pulse increasing direction in the servo motor CCW or positive direction
1: Encoder pulse decreasing direction in the servo motor CCW or positive direction
[Pr. PC27.2_ABZ phase input interface encoder ABZ phase connection assessment
function selection]
Select the non-signal detection status for the pulse train signal from the A/B/Z-phase input interface encoder used as a linear
encoder or load-side encoder.
This function is enabled when an A/B/Z-phase input interface encoder is used.
[Pr. PC27.5_Scale measurement encoder selection]
Select a scale measurement encoder when using an A/B/Z-phase differential output type encoder.
This setting is enabled only when an A/B/Z-phase differential output type encoder is connected to CN2L or CN2AL.
If this servo parameter is set to "1" in the standard control mode or direct drive motor control mode while connected to an A/B/
Z-phase differential output linear encoder, [AL. 01A Servo motor combination error] occurs.
If this servo parameter is set to "1" in the standard control mode or linear servo motor control mode while connected to an A/
B/Z-phase differential output rotary encoder, [AL. 01A Servo motor combination error] occurs.
0: Use the A/B/Z-phase differential output type encoder as a scale measurement encoder
1: Use a serial encoder as a scale measurement encoder
