3.2.20 Vibration Detection Level Initialization (Fn01B)

This function detects vibration when servomotor is connected to a machine in opera-
tion and automatically adjusts the vibration detection level (Pn312) to output more
exactly the vibration alarm (A.520) and the vibration warning (A.911).
The vibration detection function detects vibration elements according to the motor
speed.
Pn310
If the vibration exceeds the detection level calculated by the following formula, the
alarm or warning will be output according to the setting of vibration detection switch
(Pn310).
Detection level =
Vibration detection level (Pn312 [min
• Use this function if the vibration alarm (A.520) or the vibration warning (A.911) is
not output correctly when a vibration at the factory setting of the vibration detec-
tion level (Pn312) is detected. In other cases, it is not necessary to use this func-
tion.
• The vibration alarm or warning detection sensibility differs depending on the
machine conditions. In this case, fine-tune the setting of the vibration detection
sensitivity (Pn311) using the above detection level formula as a guide.
