Appendix B Maintenance and
Inspection
■Basic Inspection
Item Content
General inspection
Periodically check if the screws of the servo drive, the connection
between the motor shaft and the mechanical system as well as
the connection of terminal block and mechanical system are
securely tightened.
The gap of the control chamber and the installation of the cooling
fan should free from oil, water or metallic particles. Also, shall the
servo drive free from the cutting power of the power drill.
If the control chamber is installed in the site which contains
harmful gas or full of dust, please be ensure the servo drive is free
from the harmful gas and dust.
When making encoder cable or wire rods, please be ensure the
wiring is correct. Otherwise, the motor may have sudden
unintended acceleration or be burned.
Inspection before
operation
(has not applied to
the power yet)
To avoid the electric shock, the ground terminal of the servo drive
should firmly connect to the ground terminal of the control
chamber. If the wiring is needed, wait at least 10 minutes after
disconnecting the drive from the main supply power, or discharge
electricity by discharge device. (Please wait until the power
indicator is off.)
The splicing parts of the wiring terminal should be isolated.
Make sure the wiring is correct so as to avoid the damage or any
abnormity.
Check if the electric conductivity objects including sheetmetal (such
as screws) or inflammable objects are not inside the servo drive.
Check if the control switch is in OFF status.
Do not place the servo drive of external regenerative resistor on
inflammable objects.
