|
|
| Periodically inspect the screws of the servo drive, motor shaft, terminal block and |
|
|
| the connection to mechanical system. Tighten screws as necessary as they may |
|
|
| loosen due to vibration and varying temperatures. |
|
|
| Ensure that oil, water, metallic particles or any foreign objects do not fall inside the |
| General Inspection |
| servo drive, motor, control panel or ventilation slots and holes. As these will cause |
|
| damage. | |
|
|
| |
|
|
| Ensure the correct installation and the control panel. It should be free from airborne |
|
|
| dust, harmful gases or liquids. |
|
|
| Ensure that all wiring instructions and recommendations are followed; otherwise |
|
|
| damage to the drive and or motor may result. |
|
|
| Inspect the servo drive and servo motor to insure they were not damaged. |
|
|
| To avoid an electric shock, be sure to connect the ground terminal of servo drive to |
|
|
| the ground terminal of control panel. |
|
|
| Before making any connection, wait 10 minutes for capacitors to discharge after |
|
|
| the power is disconnected, alternatively, use an appropriate discharge device to |
|
|
| discharge. |
| Inspection before |
| Ensure that all wiring terminals are correctly insulated. |
|
| Ensure that all wiring is correct or damage and or malfunction may result. | |
| operation |
| Visually check to ensure that there are not any unused screws, metal strips, or any |
| (Control power is not |
| |
|
| conductive or inflammable materials inside the drive. | |
| applied) |
| |
|
| Never put inflammable objects on servo drive or close to the external regenerative | |
|
|
| |
|
|
| resistor. |
|
|
| Make sure control switch is OFF. |
|
|
| If the electromagnetic brake is being used, ensure that it is correctly wired. |
|
|
| If required, use an appropriate electrical filter to eliminate noise to the servo drive. |
|
|
| Ensure that the external applied voltage to the drive is correct and matched to the |
|
|
| controller. |
|
|
| Ensure that the cables are not damaged, stressed excessively or loaded heavily. |
|
|
| When the motor is running, pay close attention on the connection of the cables and |
|
|
| notice that if they are damaged, frayed or over extended. |
|
|
| Check for abnormal vibrations and sounds during operation. If the servo motor is |
|
|
| vibrating or there are unusual noises while the motor is running, please contact the |
|
|
| dealer or manufacturer for assistance. |
|
|
| Ensure that all |
| Inspection during |
| of various machinery are different, in order to avoid accident or cause damage, do |
| operation |
| not adjust the parameter abnormally and ensure the parameter setting is not an |
| (Control power is |
| excessive value. |
| applied)) |
| Ensure to reset some parameters when the servo drive is off (Please refer to |
|
|
| Chapter 7). Otherwise, it may result in malfunction. |
|
|
| If there is no contact sound or there be any unusual noises when the relay of the |
|
|
| servo drive is operating, please contact your distributor for assistance or contact |
|
|
| with Delta. |
|
|
| Check for abnormal conditions of the power indicators and LED display. If there is |
|
|
| any abnormal condition of the power indicators and LED display, please contact |
|
|
| your distributor for assistance or contact with Delta. |
