the vibration occurs.
When the gap is too big, even if setting the notch filter, the resonance cannot be suppressed completely. At this time, increase
the [Torque command Notch filter depth selection(No.170.0)] to get the shallower filter performance. When multiple notch
frequency exist, increase the [Torque command Notch filter width selection(No.169.0)] to widen the notch frequency.

Vibration reduction methods for low-pass filter
The adjustment method for torque command low-pass filter No. 160. 0
、
162. 0 are shown below.
Set the [Option for Torque command low-pass filter(No. 160. 0) to “1”(Enable). The default value is “1”(Enable) at factory
shipment. Increasing [Torque command preliminary filter time constant for Low-pass filter(No. 162. 0)] can help to suppress
the resonance. But if increase too much, it will cause some other vibration.
The maximum value is based on the following formula.
8.9 Home position return
8.9.1 Overview
The home position return is the operation of coordinating the command and mechanical coordinates within the drive. When
using the positioning function in the drive, perform the home position return according to the actual needs.
■
Using incremental system
Home position return must be done when power-ON.
■
Using absolute system
The encoder battery backs up after power OFF. So when the home position return is performed once in installation, there’s no
need to have the home position return after power ON again
When using the positioning function in the drive, perform the home position return according to the actual needs.
