Chapter 5
Steps for Commissioning and Tuning
The chapter is divided into two parts for explaining the commissioning operation. The first part is the no-
load detection and the second one is the detection for installation in the machine. For safety reasons, the user
must conduct the testing for the first part.
5.1.
No-load detection
To avoid the damage to the servo drive or mechanism, remove the load connected to the servo motor first.
(The coupling and relevant accessories on the axle of the servo motor must also be removed. The reason is
to avoid the situation that the accessory not removed from the axle of the servo motor flies off, indirectly
causing the personal injury or equipment damage.) If the servo motor operates normally according to the
normal operating procedure after the removal of the load connected to the servo motor, connect the load
back to the servo motor afterwards.
Strongly recommended: Make the servo motor to go into the normal operation under the unloaded condition
and connect the motor to the load afterwards to avoid danger.
Check the items listed below one by one to find out problems and solve them before the motor operation to
prevent the damage afterwards:
Detection before
operation
(no control power
supply provided)
Check the servo drive for evident damage.
Insulate the connecting part of the distribution terminal.
Check the wiring for completion and accuracy to prevent damage
or abnormality.
Check if there is any conductive object such as the screw or a sheet
metal or any flammable object in the servo drive.
Check if the control switch is OFF.
The regenerative resistor of the servo drive or the external
regenerative resistor must not be placed on any flammable object.
To prevent the electromagnetic actuator from becoming
ineffective, check if the circuit causing the immediate termination
of operation and cutting the power off operates normally.
If the electronic instrument near the servo drive suffers from the
electromagnetic interference, use an instrument for mitigation.
Check if the applied voltage level of the drive is accurate.
