[Pr. PA03_Absolute position detection system (*ABS)]
[Pr. PA03.0_Absolute position detection system selection]
Set this servo parameter when using the absolute position detection system. If the absolute position detection system is
switched to the incremental system, the home position is erased. Execute homing again when the absolute position detection
system is enabled.
0: Disabled (incremental system)
1: Enabled (absolute position detection system)
In the following case, enabling the absolute position detection system triggers [AL. 037 Parameter error].
• When an incremental type encoder is being used
• When semi closed/fully closed switching is enabled
By setting [Pr. PF63.0 [AL. 01A.5 Servo motor combination error 3] selection] to "1" (disabled) while the absolute position
detection system is enabled, an in-use servo motor with a batteryless absolute position encoder can be replaced without
changing the setting value of [Pr. PA03.1 Servo motor replacement preparation].
Connecting a servo motor that had not been connected at the startup of the absolute position detection system will cause [AL.
025 Absolute position erased], erasing absolute position data.
Therefore, check if a correct servo motor is connected.
[Pr. PA03.1_Servo motor replacement preparation]
To replace an in-use batteryless absolute position encoder equipped servo motor while the absolute position detection system
is in enabled status, set this servo parameter to "enabled".
Selecting "1" (enabled) enables servo motor replacement. After completing the servo motor replacement preparation, the
value automatically changes to "0" (disabled).
After replacing the servo motor, the home position is erased. Execute homing again.
If [AL. 01A.5 Servo motor combination error 3] occurs after servo motor replacement, set this servo parameter to "1"
(enabled), cycle the power, and then deactivate [AL. 01A.5].
0: Disabled
1: Enabled
[Pr. PA03.2_Scale measurement encoder replacement preparation]
To replace an in-use batteryless absolute position scale measurement encoder while the absolute position detection system is
in enabled status, set this servo parameter to "enabled".
Selecting "1" (enabled) enables scale measurement encoder replacement. After completing the scale measurement encoder
replacement preparation, the value automatically changes to "0" (disabled).
After replacing the scale measurement encoder, the home position is erased. Execute homing again.
After setting this servo parameter to "enabled", cycle the power and then deactivate [AL. 1A.6 Servo motor combination error
4].
0: Disabled
1: Enabled
