Maintenance and Inspection of Servo Unit1.7.
The servo system is made up of many parts. The equipment performs its functions only when
all the parts work properly. In mechanical parts and electronic parts, some parts need to be
maintained depending on the conditions of use. It must be regularly checked or replaced according
to the service-time to ensure that the servo motor and servo drive can operate normally for a long
time.
Overhaul of Servo Motor1.7.1.
Since the AC servo motor does not have the electric brush so that only a simple daily
maintenance is required. The maintenance period in the table is a rough standard. Please judge
and determine the most appropriate time for repair according to the conditions of use and use
environment.

please do regular inspections. In addition, please refer to the following table for the standard
number of years of replacement, and contact our agency or sales office. After the inspection, we
will judge whether we need to replace the parts. The servo unit serviced by our company has its
user parameters adjusted back to the factory settings. Be sure to reset the user parameters before
use by yourself.

Panel Operation2.
Basic Operation2.1.
Keys’ Names and Functions of the Panel Operator2.1.1.
The panel operator consists of panel monitor and keys. The panel operator could display
condition, operate the accessory functions, set parameters and monitor the motions of the drive
unit. The panel operator keys’ names and functions are shown as below:

Auxiliary Functions Operation of Fn group2.2.
Auxiliary functions are about performing the settings and adjustment of the drive unit. The
panel operator displays the numbers which begin with Fn.

Let me introduce the parameters Pn’s setting method:Take the setting method of the speed
loop gain rise from 40.0 to 100.0 as an example:
1. When the setting range is within 5-digit numbers. Because the panel operator could
only display 5-digit number, so the setting display with 6-digit number is shown as
