4.5 Testing

This section is divided into two parts. The first part introduces testing without load and the

second part describes testing when the servo motor is running with load. To avoid danger,

operate the servo motor without load first.

4.5.1 Testing without load

Remove the load from the servo motor, including coupling on the shaft and accessories, to

avoid any damage to the servo drive or machine. This prevents the parts on the motor shaft

from falling off and possibly causing personnel injury or equipment damage during operation.

Run the motor without load first to see if the servo motor can run during normal operation.

Caution: to prevent danger, it is strongly recommended that you check if the motor can operate

normally without load first. Then, try operating the motor with load.

Check the following items carefully before operation.

Inspection before

operation

(without power)

Inspection during

operation

(power is applied)

◼ Check for any obvious visible damage.

◼ The wires at the wiring terminal should be isolated.

◼ Make sure the wiring is correct to avoid damage or any abnormal

operation.

◼ Check for and remove any electrically conductive objects, including sheet

metal and screws, or inflammable objects inside or near the servo drive.

◼ Check if the control switch is in the Off state.

◼ Do not place the servo drive or external regenerative resistor on

inflammable objects.

◼ To ensure the electromagnetic brake works, check if the stop and circuit

breaker functions are working normally.

◼ Reduce the electromagnetic interference if there is electromagnetic

interference with the peripheral devices.

◼ Make sure the external voltage level of the servo drive is correct.

◼ Protect the encoder cable from excessive stress. When the motor is

running, make sure the cable is not worn or stretched.

◼ Contact Delta if the servo motor vibrates or makes unusual noise during

operation.

◼ Make sure the settings for the parameters are correct. Different machinery

has different characteristics. Adjust the parameters according to the

characteristics of each machine.

◼ Reset the parameters when the servo drive is in the Servo Off state, or it

may cause malfunction.

◼ If there is no contact noise or other abnormal noise when the relay is

operating, please contact Delta.

◼ Check if the power indicator and LED display work properly.

◼ The 7.5 kW model is controlled by PWM. When the temperature is lower

than 40°C (104°F), the fan stops running.
