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 be free
from oil, water or metallic particles. Also, the servo drive shall be 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 ensure the servo drive is free from the harmful gas and dust.
When making detector (encoder) cable or wire rods, please ensure the wiring is
correct. Otherwise, the motor may have sudden unintended acceleration or be
burned down.
To avoid electric shock, the ground terminal of the servo drive should be firmly
connected to the ground terminal of the control chamber. If the wiring is needed, wait
at least 10 minutes after the drive is disconnected from the mains, or discharge the
electricity by discharge device.
The splicing parts of the wiring terminal should be isolated.
Make sure the wiring is correct so as to avoid damage or any irregularity.
Check if the electrically conductive objects such as screws, sheet metal 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 onto inflammable
objects.
To avoid the electromagnetic brake losing efficacy, please check if the 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.
The detector (encoder) cable should avoid excessive stress. When the motor is
running, please ensure the cable is not frayed by the machine or over extended.
Please contact Delta if there is any vibration of the servo motor or unusual noise
during operation.
Make sure the setting of the parameters is correct. Different machinery has different
characteristic, please adjust the parameter according to the characteristic of each
machinery.
Please reset the parameter when the servo drive is in the status of SERVO OFF, or it
may cause malfunction.
Please contact Delta if there is no contact sound or other irregular sound occurs
when the relay is operating.
Check if the power indicator and LED display works normally.
