1 SERVO PARAMETER DETAILS
1.7 Extension setting 3 servo parameters group ([Pr. PF_ _ ])
[Pr. PF46_Vibration failure prediction - Standard deviation (VSD)]
Set the vibration level standard deviation during servo motor operation.
This servo parameter is enabled when [Pr. PF34.0 Friction failure prediction warning selection] is set to "2" (enabled (manual
threshold setting)).
When [Pr. PF34.0 Friction failure prediction warning selection] is set to "1" (enabled (automatic threshold setting)), the value
will be calculated automatically from the estimated friction torque at rated speed.
[Pr. PF47_Servo motor total travel distance offset (TMO)]
Set an offset value for machine total travel distance.
After the equipment is replaced, set this servo parameter.
[Pr. PF62_Function selection F-14 (FOP14)]
[Pr. PF62.0_Backlash estimation unit selection]
Select the unit for "travel distance at backlash estimation" which is to be automatically set in the backlash estimation function.
0: Command pulse unit
1: Servo motor encoder pulse unit
A time-out will occur at execution of the backlash estimation function depending on the setting values for the electronic gear
([Pr. PA06 Electronic gear numerator]/[Pr. PA07 Electronic gear denominator]). When a time-out occurs, set this servo
parameter to "1".
When this servo parameter is "0", the servo motor rotation amount is as follows.
Servo motor rotation amount = travel distance at backlash estimation × ([Pr. PA06]/[Pr. PA07]) [rev]
For "travel distance at backlash estimation", refer to "Gear failure diagnosis function" in the User's Manual (Function).
