[Pr. PF63.2_Servo amplifier replacement data save selection]
Whether or not to store the servo amplifier replacement data can be set for equipment which uses an absolute position
detection system with a servo motor with a batteryless absolute position encoder.
0: Disabled ([AL. 025 Absolute position erased] occurs at servo amplifier replacement.)
1: Enabled ([AL. 025 Absolute position erased] does not occur at servo amplifier replacement.)
With "1" (enabled) set, [AL. 025] does not occur even when the power is turned on after servo amplifier replacement. This
enables positioning operation without performing homing again.
For a multi-axis servo amplifier, the latest setting value of this servo parameter is applied to all axes as the setting method is
"Common". The setting cannot be changed separately for specific axes.
When the setting value of this servo parameter is "1" (enabled), values are automatically set for [Pr. PC84 Servo amplifier
replacement data 1] to [Pr. PC95 Servo amplifier replacement data 12].
[Pr. PF66_Gear setting for backlash estimation (BLG)]
[Pr. PF66.0-3_Gear for backlash estimation - Numerator]
Set the gear ratio numerator of the gear connected to the servo motor in hexadecimal. If multiple gears are connected to the
servo motor, set the gear ratio up to where the load is applied.
If the gear ratio numerator and the denominator cannot be expressed by numbers up to "2
16
-1", round up the gear ratio and
set a value equal to or less than "2
16
-1" for both the numerator and the denominator.
[Pr. PF66.4-7_Gear for backlash estimation - Denominator]
Set the gear ratio denominator of the gear connected to the servo motor in hexadecimal. If multiple gears are connected to the
servo motor, set the gear ratio up to where the load is applied.
If the gear ratio numerator and the denominator cannot be expressed by numbers up to "2
16
-1", round up the gear ratio and
set a value equal to or less than "2
16
-1" for both the numerator and the denominator.
