Chapter 5 Trial Operation and
Tuning
This chapter is divided into two parts to describe the trial operation. The first one is the inspection
without load and another one is the inspection with load. For safety reasons, please conduct the
first inspection.
5.1 Inspection without Load
Please remove the load of the servo motor, including coupling on the shaft and accessories so as
to avoid any damage on servo drive or mechanism. This is aiming to avoid the falling off of the
disassembled parts of the motor shaft and indirectly causing the personnel injury or equipment
damage during operation. Running the motor without load, if the servo motor can run during normal
operation, then it can connect to load for operation.
Caution: Please operate the servo motor without load first. If the servo motor runs normally,
connect the load afterwards in order to avoid any danger.
Please check the following items before operation.
Inspection before operation (has not applied to the power yet)
Check if there is any obvious damage shown on its appearance.
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 or 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 running the servo drive (has already applied to the power)
The encoder cable should avoid excessive stress. When the motor is running, make sure the
cable is not frayed or over extended.
