Revision February, 2017 B-1
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, the servo drive
shall 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 ensured the servo drive is free from the
harmful gas and dust.
When making encoder cable or wire rods, please be ensured 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.
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.
To avoid the electromagnetic brake losing efficacy, please check if stop
function and circuit break function can work normally.
If the peripheral devices are interfered by the electronic instruments,
please reduce electromagnetic interference with devices.
Please make sure the external voltage level of the servo drive is
correct.
Inspection before
The encoder cable should avoid excessive stress. When the motor is
running, please be ensured the cable is not frayed or over extended.
