Utility Function Mode
(1) Preparation
The following conditions must be met to initialize the vibration detection level.
• The write prohibited setting (Fn010) must not be set to write-protect parameters.
• The test without a motor function must be disabled (Pn00C.0 = 0).
(2) Operating Procedure
Use the following procedure.
• The vibration may not be detected because of improper
servo gains. Also, not all kinds of vibrations can be
detected. Use the detection result as a guideline.
• Set a proper moment of inertia ratio (Pn103). Improper
setting may result in the vibration alarm, warning misde-
tection, or non-detection.
• The references that are used to operate your system must
be input to execute this function.
• Execute this function under the operating condition for
which the vibration detection level should be set.
• Execute this function while the motor speed reaches at
least 10% of its maximum.
