7 ABSOLUTE POSITION DETECTION SYSTEM
7.1 Outline
Checking the detected absolute position data
Absolute position data can be checked with MR Configurator2.
Choose "Monitor" and "ABS Data Display" to open the absolute position data display screen.
Procedure of replacing a servo motor with battery-less absolute
position encoder
To replace a servo motor with battery-less absolute position encoder, use the following procedure.
1.
Replacing the servo motor
Turn off the power and replace the servo motor.
2.
Canceling [AL. 01A Servo motor combination error]
After the power is turned on, [AL. 01A.5 Servo motor combination error 3] occurs.
After setting [Pr. PA03.1 Servo motor replacement preparation] to "1" (enabled), cycle the power and then deactivate [AL.
01A.5].
3.
Homing
The absolute position data is erased by servo motor replacement. Perform homing again before operation.
No.
Item
Screen operation
(1)
Motor (machine) side pulse unit value
Acquires and displays values in the unit of the servo motor (machine) side pulses from the servo
amplifier of the specified axis.
(2)
Command pulse unit value
Acquires and displays the command pulse unit value from the servo amplifier for the specified axis.
(3)
CYC
[G] [WG]: Acquires and displays the position within one revolution in the unit of the servo motor
(machine) side pulses from the servo amplifier of the specified axis.
[A]: The command pulse data of the position within one-revolution is acquired from the servo amplifier of
the target axis and displayed.
(4)
ABS
Acquires and displays the multi-revolution counter travel distance from the absolute home position from
the servo amplifier of the specified axis.
(5)
CYC0
[G] [WG]: Acquires and displays the home position within one revolution in the unit of the servo motor
(machine) side pulses from the servo amplifier of the specified axis.
[A]: The command pulse data of the home position within one-revolution is acquired from the servo
amplifier of the target axis and displayed.
(6)
ABS0
Acquires and displays the multi-revolution counter value of the absolute home position from the servo
amplifier of the specified axis.
