[Pr. Pf31_Machine Diagnosis Function - Friction Estimate Area Judgment Speed At Low Speed (Fric)]; [Pr. Pf32_Oscillation Detection Alarm Time (*Vibt)] - Mitsubishi Electric MR-J5-G User Manual

[Pr. PF31_Machine diagnosis function - Friction estimate area
judgment speed at low speed (FRIC)]
Initial value
0 [r/min], [mm/s]
Set the servo motor speed to divide the friction estimation area between low-speed and high-speed in the friction estimation
process of machine diagnosis.
When the maximum operation speed is under the rated speed, it is recommended to set half the value of the maximum
operation speed.
When "0" is set, the judgment speed is half of the rated speed.
The setting value will be clamped at the permissible maximum speed.
By setting [Pr. PF34.6 Friction estimate area judgment speed setting] to "1" (automatic setting), this servo parameter value will
be automatically calculated from the operation pattern during servo motor driving and overwrite the value.
Set a value larger than [Pr. PC07 Zero speed] for this servo parameter. If the value is equal to or lower than zero speed, the
friction estimation process does not function.

[Pr. PF32_Oscillation detection alarm time (*VIBT)]

Initial value
50 [100 ms]
Set the time from when oscillation is detected until the occurrence of an alarm or warning.
When "0" is set, the time until the occurrence of the alarm or warning is 5000 ms.
When an oscillation detection alarm or warning is generated during normal operation, set a value larger than "10" (1000 ms).
